Trek Checkpoint ALR 5 review – a confident, capable gravel bike

Trek's updated aluminum checkpoint is a surefooted, confidence-inspiring ride that's perfect for ruined back lanes, byways and well-laden travels.

BikePerfect Verdict

The reshaped Checkpoint frame neatly combines confidence-inspiring stability with a fun, engaging feel which goes well at all speeds on all sorts of surfaces. This might not be the lightest or fanciest build, but the key bits are great and the rest just quietly works.

Stable and predictable

Comfortable

Great shifting and brakes

Gearing a bit tall for the weight

Could use a dropper post

The aluminium-framed ALR models sit at the bottom of Trek's Checkpoint range, with the lighter carbon SL and race-focused SLR bikes above, but in truth that's not a bad place to be. The ALR 5 gets a full set of excellent Shimano GRX components for the drivetrain and brakes, decent tires on tubeless-ready rims and lots of rack and fender mounts. 

The result is a surefooted, confident bike that's ready for exactly what Trek says it's for – gravel riding for fun, commuting or just general adventures. Which is pretty much what most people are after when looking for the best gravel bikes or best cheap gravel bikes .

Design and geometry

For 2023, the Checkpoint frame has seen some changes – basically it's got longer both in the front centre and the chainstays, and the stem is shorter to compensate. I tested a 58cm, and compared to the 2021 model it has 10mm longer chainstays, 20mm more reach and is 26mm longer overall. The 90mm stem and 60.9cm/41.1cm stack and reach figures keep the overall riding position fairly relaxed, with a usefully tall front end and slightly head-down, but certainly not front heavy, bias.

The head angle is the same as before at 72.3 degrees, presumably to keep the steering decently snappy, as is the bottom bracket drop at 7.4cm. 

This might be the 'poor man's' model with its humble alloy frame, but that doesn't mean it's unsophisticated. The various touring-friendly mounts are complimented by internally-routed cables that help a lot when strapping on frame bags or cages, as well as keeping them generally out of harm's way. I did find several of the bungs protecting the mounting/cable holes disappeared overboard on rough trails though, so if you want to keep filth out of your threads/frame you might want to stock up – or wind in some actual bolts where you can.

Components and build

Trek has spent the budget wisely here, speccing the excellent Shimano GRX shifters, levers and hydraulic brakes. The flat-fronted levers are particularly good for grip when it's rough, the shifts are always positive and the two-piston calipers are powerful and easy to modulate on the 160mm discs. Basically, the whole stop and go thing is covered perfectly.

Well, almost perfectly. The 2x11 drivetrain gives a very useable spread of ratios, but for the most serious off-road climbing it's a little high. At the top end it's good for 35mph before you spin out, which is great for the road and fireroad descents, but leaves the lowest gear (30/34t) slightly high for the steepest, techiest climbs. That's especially true if the bike's loaded up.

That's the lowest combination of ratios that will fit, though, so your options there are either to keep the bike as light as possible, fit a 1x crank and lose a fair bit of top speed, or get stronger...

The finishing kit is all in-house Bontrager stuff, and while it's all perfectly good they're pretty easy targets for weight loss upgrades. The Bontrager Elite Gravel bar is 44cm wide on this frame size with a good flare to the drops for extra leverage, and the comfy GRX hoods tilt inwards just enough to encourage a slightly elbows-out stance that's good for control.

The wheels – Switch hubs, 21mm wide Paradigm rims (the SL version on one end, presumably the front) and 24 spokes on each – are similarly utilitarian, being strong, middling for weight and entirely decent for the job. Wearing Aeolus XXX rim strips they're tubeless ready, and so are the Bontrager GR1 Team Issue tires, which is nice – in fact, Trek lists 6oz of its TLR sealant as a 'tire part,' so presumably consumer bikes are supplied already set, just as our test bike was.

The tires are predictable and confidence inspiring on the unusually dry terrain of our test period, as well as on tarmac both damp or dry, but are clearly not designed for mud. There's room in the frame for up to 45mm rubber should you want to go wider.

Oh, and while the front axle looks like you'll need to carry a hex key to get it out, the lever on the rear thru-axle actually pulls out to fit in either one. 

Performance

The Checkpoint has a confident feel – its length and reasonable heft keep it planted, while the steering is stable without being sluggish. It's the same whether you're on gravel or tarmac, and predictable in a friendly but not boring way. The chunky headtube and sizeable welded junctions do a great job of keeping it tracking where it's pointed in the rough.

Despite the chunky, almost box-section seatstays and generally rigid-feeling frame, it's comfortable for long rides, thanks to the high volume tyres, well-cushioned bar tape and a supportive, hammocky P3 Verse Comp saddle you really sit 'in'.

Get up some speed on gravel though and there's no disguising the aluminum build. By 30mph on a fireroad, your hands and feet are taking some serious vibes, and the chatter from sustained speed does reduce comfort. 

Switching to carbon at the bar (and at the Bontrager seatpost) would both increase comfort and reduce weight, and though I found the saddle supportive and comfy both for long rides and hard pedaling efforts, it does have steel rails – it's another easy and relatively cheap target for weight loss and vibe reduction.

Alternatively, if you want more speed whatever the trails do, fit the best dropper post that will suit the 27.2mm seat tube and reap the rewards.

Personally, I would have quite liked the shorter cranks of the smaller sizes instead of the 175mm GRX RX600s fitted here, which would allow an even lower BB for descending confidence, but that's really just preference. The 7.4cm BB drop is pretty low in the scheme of things, cornering feel is predictable, and ground clearance is good.

This is an extremely usable yet still very enjoyable bike. It nails that '2/3rds road bike, 1/3rd XC bike' feel that makes gravel bikes so good for so many things – commuting while avoiding the worst traffic, touring, exploring dilapidated rural lanes, getting in hard climbing efforts away from ANY traffic, or just generally getting out there and enjoying the view. 

It's comfortable and reassuring from the off whatever the surface, and the money's been spent in the right places – this is a really solid base for years of riding fun.

Canyon Grail Vs Trek Checkpoint

The big brand gravel bike battle! Canyon vs Trek! Which gravel bike is best? We are going to compare these two iconic gravel bikes side by side and see what the difference is between each. When it comes to price the Grail ranges from $2,299 to $9,549 while the Checkpoint ranges from $2,499.99 to $12,249.99 . But what really is the difference and which one is best for you and your riding goals?

There are so many different models to choose from for each bike. For this article, we have taken their mid-range (best bang for buck option as a main comparison. Instead of comparing all models together.)

The Canyon Grail was built to be a bike that maintains similar performance and speed to a road bike on asphalt while also offering the comfort and control, a road bike may lack, on gravel.

When comparing the Canyon Grail CF SL 8 Model to the Trek Checkpoint SL 5 model, (which both cost the same $4,499, the Canyon Grail is 700 grams / 1.54 pounds lighter and more focused on speed and performance when comparing the geometry of both bikes. Meaning the Checkpoint is more comfortable the longer you stay in the saddle, thanks to a more upright stack/reach ratio. The Trek also seems to offer more mounting options to carry all the necessary gear you may need for a minimal bikepacking trip.

When it comes to tire clearance the Grail can fit up to 42 mm while the Checkpoint fits 45mm x 700c or 2.1″ (which is approx 53 mm) x 650b wheels. The Trek has clearance for slightly wider tires which further lends itself to be the superior bike when it comes to all-around adventure.

Both are similar when it comes to gearing (both with 2×11 GRX 800 drivetrains) and hydraulic disc brakes. Different tires with the same 40 mm width, with the Grail on Schwalbe G-One R 40mm and Checkpoint on Bontrager GR1 Team Issue 700c x 40 mm tires.

When taking a look at these bikes’ gearing we found that the Checkpoint has 46-30T crank vs the Grails 48-31T crank and both bikes have 11-34T cassettes in the rear. Both with the same 700c x 40 mm tires. We can calculate that the Checkpoint has a better climbing gear of 24.32″ while the Grail has 25.15″. Meaning that the Checkpoint is slightly more capable when it comes to climbing especially if you plan to use the bike for bikepacking with gear. When it comes to the largest gear is often attributed to riding fast on the flats or riding downhill. The Grail offers a 120.50″ vs the Checkpoints 115.53″, meaning the Grail offers more gearing for those fast sections.

Compare these bikes to the Cannondale Topstone!

Canyon Grail Vs Cannondale Topstone

Cannondale Topstone Vs Trek Checkpoint

The main difference is in the bike’s geometries. With the Grail with a more aggressive stack/reach ratio (1.27 vs 1.42), the chainstay is 10 mm longer on the Checkpoint and Wheelbase is 12 mm longer too. Again making for a more planted feel when under a load. The trail is 4mm longer on the Checkpoint and the standover height is around 45 mm lower than the Checkpoint. However, the BB Drop and BB Heights are very close with a 1 mm difference. This data is for both medium-sized bikes.

Based on the above information we can conclude that the Checkpoint is better suited for gravel adventure riding where comfort and gear-carrying ability are a main priority, which are some of the main things to look for in an adventure gravel bike. The Grail seems better suited as a gravel racing bike to ride nothing but fast!

Canyon Grail

Cover huge distances at speed and in comfort (as stated by Canyon but when compared to the Checkpoint simply due to the much lower stack/reach comfort would be sacrificed over the long haul). However, that is the promise by Canyon with their Grail gravel bike.

It is the ultimate all-rounder, offering road bike speed, all-terrain control, and grip with stable but also agile handling. The CF SLX model is designed to win races, while they also offer other more accessible models if you just want to ride fast and save some coin.

The Grail is more focused on speed and performance on gravel terrain compared to the more all-rounder/adventure cargo-carrying friendly Checkpoint. The Grail has been used in some long-distance endurance events. Featuring a spot amongst some of the  fastest gravel bikes . The Grail comes in 12 different build options including women’s gravel bikes.

Trek Checkpoint

Every gravel grinder and their dog seem to have one of these bikes. So that means they are a great carbon gravel bike option, right? The main feature of the Checkpoint is the lightweight OCLV Carbon frame with IsoSpeed, a decoupler at the top tube/seat tube junction that provides additional compliance over rough terrain so you can stay stronger for longer. A carbon gravel bike made for epic all-road adventures. Explore all models here .

The Checkpoint is the best all-rounder out of the two. More adventure-focused than the Grail, it’s still fast, but more importantly comfortable and smooth, and its versatile design ensures that you’ll reach all the places you dream of exploring on two wheels. If you want to mostly explore (I mean why else would you get a gravel bike?) Then the Checkpoint would be the best option .

Geometry – Grail Vs Checkpoint

Geometry can play a big part in the difference between how a bike rides and feels. It is definitely something to consider when buying a bike. At first impressions, I was expecting the Grail to be more of a road bike geometry. And that provided to be true with the slightly shorter chainstay and wheelbase for more responsive and snappy control. But all the measurements below are in mm and are for both medium-sized bikes. We can clearly see in the dark red that the Checkpoint is the more upright and therefore comfortable and adventure-focused bike out of the two.

Want to learn more about understanding bike geometry? Read this article which goes through all the jargon and what it means for a comfortable ride!

The main difference between the two bikes is the stack/reach ratio, being much more aggressive on the Grail. Meaning the Checkpoint is better suited for a more upright riding position adding more comfort in the saddle for those long adventures. This would make the Grail more efficient and faster to ride.

Along with this the Chainstay and Wheelbase are longer on the Checkpoint making it feel a little more planted for loaded adventures. And making the Grail a better bike for speed and performance. You want a shorter chainstay in the rear for quick and snappy bike control.

If you plan to mostly go on adventures with gear the Checkpoint is a no-brainer . But if you are looking for a speedy gravel bike that will keep up with your roadie mates it’s definitely the Grail. People still use the Grail for bikepacking too. However mostly pavement bikepacking with some light gravel. You just benefit a little more with the Checkpoint for bikepacking thanks to its more adventure-focused geometry for stability and comfort. Along with mounts on the forks.

If you plan to cart gear and use your bike for transporting cargo in the form of bikepacking bags. You might be better off with the Checkpoint for its longer wheelbase to avoid heel striking when compared to a shorter wheelbase on the Grail. This longer wheelbase adds better overall stability when the bike is under more of a load.

It seems if you are coming from a roadie background and are looking for a bike with larger tire clearance the Grail is your go-to. Allowing you to maintain the performance of a road bike but have the ability to ride gravel more comfortably and efficiently, compared to a road bike.

But if you want a gravel bike that can ride road just as well as gravel but also take you on bikepacking trips with reasonable comfortability. The Trek Checkpoint is the do-it-all solution out of the two bikes .

However, both bikes are amazing in their own right. And at times it can be difficult to recommend one bike over the other when they are both great bikes and offer something special. But I hope this article clears up some questions you might have had.

Trek Checkpoint Review (SL6): Dirt Road Rocketry

Joe spent a few weeks with Trek’s Checkpoint SL6 to run it through challenges ranging from the weekly fast roadie coffee shop ride to a ten-hour dirt randonee to local gravel and singletrack explorations. Is this go-fast bike the bridge between a svelte carbon road machine and a lumbering gravel tourer?

Trek isn’t always first to the party anymore, but no one can deny their substantial bicycle history credentials. From the 520/720 tourers of the 1970s to early production 29ers under the Gary Fisher moniker to turn-of-the-century OCLV 5200s, Trek has innovated and produced coveted rides. The recent introduction of the Stache and the 1120 bikepacking specific rig—reviewed here last February—suggests that Trek still wants to be in the conversation. Whatever one thinks of those particular wheels, the designs aren’t a lazy copy of someone else’s work.

• Quick Highlights
• Angles (56cm): 72.2° Head tube, 73° Seat tube
• Chainstay: 425mm
• Bottom Bracket: PRESS FIT BB90
• Hub specs: 12X142MM / 12X100MM Thru-Axle
• Max tire size: 700C x 45mm

The Checkpoint SL is Trek’s take on a carbon high performance drop bar bike with dual front chainrings and clearance for 45mm tires on 700c wheels. It’s available as a frameset or with Shimano Ultegra or 105, which are the SL6 and the SL5 respectively. The SL5 is available in women’s and men’s versions, though the only difference is the saddle and color. All the Checkpoint SLs feature Trek’s IsoSpeed decoupler at the seat tube/top tube junction. The idea is to separate those two tubes so that the seat tube can move with the plane of the bike to reduce jolts from the rear wheel.

My dominant impression of the Checkpoint is that it feels like a race-craving road bike. All of the cues are there: the position, the look, the instant feedback from input, and the no-flex ride. A road rider who wants to rail gravel roads at high speed will immediately be at home. The Trek shined when I took it on my local Tuesday night no-holds-barred group ride that is primarily asphalt but also sees plenty of Vermont dirt roads. On the tarmac, the Checkpoint achieves familiar prowess for a contemporary carbon bike: it jumps to task on climbs, it’s snappy to the town lines, and it’s smooth in a paceline. Once off pavement, there’s no need or sense in slowing down, as it still wants to just go. I was impressed by the consistency of this sporty aspect.

I suspect that for someone who isn’t coming from the aesthetic and mandate of road bikes, their reaction to the Checkpoint SL might be more complicated. Firstly, it’s simply not as plush at the front end as many gravel bikes. The narrower tires of the Checkpoint will be run at higher pressure, the stout fork, headtube, and downtube area is designed for precision rather than compliance, and the amount of weight on your hands while on the hoods is perfect for confident descending but reminds you when roads aren’t smooth. Secondly, the Checkpoint handles like a modern road bike in the sense that it takes effortful attention to pilot. In return, it offers quick course correction and a certain nimbleness, but it is not relaxing. It seems as if Trek took everything they knew about road bikes and sought to make a dirt-capable version without wandering too far from the essential format. That is going to have a different valence for different people.

For me, the downside to carbon bikes is that they are a little blunt to ride. There’s heavy subjectivity here, for sure, and it is hard to quantify sensation, but in my experience, excellent carbon bikes feel great—they are wonderful, after all, at mitigating road buzz when tire pressures are high—but not exemplary. Another way to put it is that, to me, there’s a ceiling to the ride quality that can be achieved on a carbon bike that is below that of lightweight steel or ti. This might be because lightweight steel and ti bikes generate a bit of frame oscillation from pedaling, and are more fun to give energy to, and therefore more fun to ride. Still, with their OCLV mastery, Trek achieve an admirable neutral to positive feel from carbon. Carbon fiber is a versatile, reliable material and the Checkpoint is an excellent carbon bike, very much near the top of its genre.

DECOUPLED SEAT TUBE

A stiff carbon bike can be a beautiful tool for a certain job, but it’s never fun to get beaten up by one. Trek’s solution is the IsoSpeed decoupler. It’s a shame that whenever a manufacturer introduces a shock absorbing measure to the back of a road bike shaped bike, it is received as a gimmick. Bike makers haven’t helped themselves since sometimes their approaches are gimmicks, but maybe suspicious consumer attitudes are changing with the wider use of split seatposts and the like. Trek brags that their technology has been proven at Paris-Roubaix, and that it was developed with input from Fabian Cancellara. Sure, bicycles have to get sold someow. I can say, though, that IsoSpeed undoubtedly works. My basis for this claim is riding the Checkpoint on dirt roads that I’ve been riding for 20 years and comparing the feel to my personal carbon bikes with similar tire pressures and widths. The back end of the Checkpoint was as comfortable as any that I’ve experienced on a performance oriented bike.

The way IsoSpeed works is that the seat tube is not molded together with the top tube and the top of the two seatstays. Instead, it passes through and is bolted to that junction to create a floating link that allows some give. The top cap that attaches the saddle to the seat tube helps in creating a system that flexes but doesn’t intrude during accelerations and sprints. Just to be clear, even though I’ve been talking about shock absorption, IsoSpeed is not and does not feel like rear suspension. It merely takes up the sharp small hits of rocks over hardpack and it keeps you in the saddle longer on chattering descents.

IsoSpeed in back but not the front does yield an asymmetry that was noticeable on the first few rides. The back end is comparatively cushy whereas the bumps intruded in a more typical way at the front end. Companies like Cannondale have put suspension on the front end of their offerings in this category, and it’s certainly intuitive to do so. In fact, it can seem strange that a bicycle would have rear shock absorption as opposed to front. I wouldn’t be surprised if Trek had a spirited internal debate about whether to include front end IsoSpeed on the Checkpoint, and, judging from pundit reaction, many people think they should have. I think things are less obvious on a performance road bike platform than first appear, though. In my experience, I can readily absorb hits and chatter by keeping my arms loose. Legs are, of course, big springs, too, but when laying down steady power from the saddle, it’s nice to not have to think about unweighting to accommodate rough stuff. IsoSpeed is there for that. Again, the front end of the Checkpoint is stiff and contributes substantially to the race bike sense of quick control. I like that in a bike that is meant to be ridden fast, and I can also appreciate the forgiving IsoSpeed back end.

WHAT’S IT FOR?

For pedaling hard with speed and purpose on dirt that isn’t very technical, the Checkpoint is as impressive a carbon bike as I’ve been on. We received the bike right before this year’s edition of D2R2 , one of the OG dirt randonées in New England (and highly recommended, incidentally). The 180k loop traverses the most scenic rolling dirt roads of Western Massachusetts and Southern Vermont. I wouldn’t necessarily recommend this kind of course as the very first ride on an untested bike, but the Checkpoint was brilliant. There are only a few sections of Class IV road that tend slightly in the direction of mountain bikes, and even these were well within the Trek’s comfort window. For pedaling over a hundred miles on dirt while trying to peg a bragging rights time, the Checkpoint is in its sweet spot. More broadly, if a training program and intervals and Strava and mixed terrain fast group rides are your style, you will very likely like this bike.

On the other hand, as one moves away from hurry and racing toward more leisurely camping intensive excursions, the Checkpoint makes less sense. It’s true that it has plenty of carry points. To wit, there are three bottle mounts in the main triangle for size 54 and up, as well as one under the downtube, and one on each fork leg. There are also bosses for a gas tank type bag behind the stem. That gives the bike great potential and flexibility if viewed in the right spirit. Suppose your friends are more into bike camping than you are, but you want to join them for an outing of a couple of nights. You can absolutely do that on the otherwise race oriented Checkpoint. Or suppose you want to mix into your fast riding the occasional rural inn-to-inn tour carrying minimal kit. This is a great platform for that, too. But, really, the Checkpoint doesn’t aim to be an all-rounder when it comes to dirt adventures.

Trek resisted the trend of claiming that 650b wheels with larger tires can be mounted on this 700c bike. They insist that the Checkpoint was designed around the 700c wheels that it is specced with. I appreciate the clarity of not claiming that the bike can be all things, and for the intended purpose of trending in the direction of racing, I think the 700c wheels are a sound choice.

A FEW MORE NOTES

The Checkpoint has a 275 lb/125 kg maximum weight including rider, gear, and bicycle. The bike features Trek’s Stranglehold micro adjustable rear dropouts. This system allows 15mm of fore-aft adjustment of the rear wheel to change the wheelbase and to adapt chainstay length to different tire sizes (Trek recommends a 28mm minimum tire). The dropouts also allow running the Checkpoint as a singlespeed. I experimented with the extremes and settled on the shortest wheelbase for its quickness. Finally, I admire the design and functional details, like the plastic shield under the downtube to protect the frame from rock hits, the metal protector on the dropped driveside chainstay for chainsuck, the smooth bottle boss covers, and the discreet fender mounts.

I haven’t said anything yet about the build on the SL6. Shimano Ultegra is flawless, and on this bike it confirmed again its reputation for shifting smoothness and mechanical refinement. I will note that the Ultegra hydraulic brakes, while very effective both in terms of modulation and stopping, tend to make a persistent scraping sound when the pads pick up mud. On a carbon frame that magnifies sounds, this is annoying. The Bontrager parts are all suitably high end, but the contact points were, for me, a study in contrast. The bars with their deep hooks and wide flat top were incredibly comfortable. The saddle—and my undercarriage is typically pretty tolerant of saddle variation— was decidedly not. The standard caveats of saddle comfort being highly individual certainly apply.

The Schwalbe G-One 35mm tires are excellent for the mix of road riding and hardpack dirt that this bike thrives in. They are a limiter, though, with respect to more broken dirt outings. The most forgiving gear is the one-to-one of the 34t small chainring and the 34t big cog. I can imagine someone wanting something more climby than that, so keep that in mind. The BB90 bottom bracket is press fit and that probably makes many of you angry, but it is perfectly standard for a carbon bike.

One last concern: I’m 5’8”/173cm and the 54cm bike fit me splendidly. But with my 31”/78.7cm inseam and slight toe-down-ish pedaling style, the cap on the seatpost that adjusts saddle height was exactly on the safety upper limit line. Perhaps my inseam is unusually long for my height, but if I was designing a bike, I would make it so that the saddle height could accommodate the tail ends of the distribution, then I’d add a centimeter or two.

What the Checkpoint is not is a Swiss army knife of all-road touring. Nor would I recommend this to someone whose image of bike camping was primarily leisurely strolls with friends to end at a nearby spot. That’s a great way to bikepack, but you don’t need and probably wouldn’t want this bike for that. Two “ifs” therefore drive my thinking about the Trek Checkpoint SL6. If I was in the market for a decidedly road bike platform that I could race and ride fast on dirt, and if the feel and advantages of carbon fiber frames was appealing, then this bike would surge high on my list. It’s refined, it’s a blast to ride while breathing hard in the drops, and the IsoSpeed coupler is effective.

Trek Checkpoint ALR 5 Review [2021 Guide]

The Trek Checkpoint ALR 5 is a versatile, high-performing gravel bike that appeals to roadies and gravel racers alike, while still offering plenty for the casual gravel rider. With the Checkpoint, Trek Bicycle pulled from their past successes, both in road bikes and cyclocross bikes, and brought to the market an all-around bike that performs on any terrain.

The Trek Checkpoint truly is a quiver-killer, burly and stable enough to take on the roads less travelled while still being light and quick enough to keep up on the weeknight group rides. The Checkpoint puts the rider in a more aggressive riding position than other offerings on the market, with a few geometry tweaks that create a stable and predictable ride compared to its cyclocross cousins.

In short, the Trek Checkpoint ALR 5 is an all-road, alloy success. Stable enough for technical, off-road riding, and race-inspired enough to feel quick and competitive on the tarmac. Furthermore, the alloy build provides great functionality without burning a hole in your wallet.

For a more detailed breakdown, read on for the full review of the Trek Checkpoint ALR 5.

Table of Contents

Trek Checkpoint Frameset

The frameset for the Checkpoint ALR 5 utilizes Treks 300 Series Alpha Aluminum with a tapered headtube leading to a carbon fiber fork. The frame includes mounts for front and rear racks, mudguards, and multiple bottle cages.

The frame also features internal cable routing, which is not only a nice aesthetic touch but also keeps the cables clean and protected from the off-road environment. The frame has a classic look with hydroformed tubes and clean welds that provide good stiffness and keep it light.

An added versatility of the Checkpoint frame is the sliding horizontal dropouts. They allow the rider to convert to a single-speed, if they so desire, or change their gearing and provide additional clearance for larger tires. I converted my Checkpoint from 2x to 1x after purchase, and the horizontal sliding dropouts provided me with the flexibility to dial in my ideal drivetrain.

ALR 5 Geometry

The geometry of the Checkpoint pulls largely from Trek’s impressive cyclocross bikes, the Boone and the Crocket, sharing the same wheelbase and chainstay length as the Boone. The Checkpoint has a few geometry tweaks, such as a lower bottom bracket and slacker seat tube angle, that make it quick and race-inspired while still being very stable on mixed terrains.

Another interesting benefit of the horizontal sliding dropouts previously mentioned is their impact on frame geometry. By increasing the wheelbase and moving the rear wheel further back in the dropouts, the bottom bracket height is slightly reduced, and the frame tube angles are further slackened. While this geometric adjustment seems slight, it will provide a more upright, stable ride feel that will suit some riders well.

These frame design elements contribute to a frame that is race-inspired and adventure ready. By sporting a frame that’s aggressive and quick on all terrains and still providing stability and predictably off the tarmac, the Checkpoint is well-suited for all-road riding, gravel racing, or being loaded up with gear for a multi-day adventure.

Checkpoint Tires

The Checkpoint comes stock with 700x40mm Schwalbe G-One tires. When the Checkpoint was initially released, it featured 35mm tires, but they have since upped the size to 40mm, which I think is huge improvement.

Out of the box, the 40mm G-Ones serve the Checkpoint well. They are quick on the tarmac, and the 40mm width offers good traction for light gravel riding. They do suffer a bit in the mud; the tread quickly fills with mud, and they get slick. But, for general purpose riding, the G-Ones are a good all-arounder.

When WTB released the new Raddler, I picked up a pair of 700x44mm’s and swapped out my G-Ones. Trek claims that the Checkpoint can accept up to a 45mm tire, so I put that to the test!

Before adjusting my wheelbase with the horizontal sliding dropouts, the Raddler just barely squeaked in there, just clearing the right chainstay by a couple of millimeters. I’ve since adjusted my rear wheel in the dropouts, and there is plenty of clearance for up to a 45mm. I often find myself in very muddy terrain, and I have yet to have any clearance issues of mud jamming up my rear wheel.

The Checkpoint ALR 5 features Bontrager’s TLR tubeless ready wheelset. They aren’t the lightest wheels in the world, but they are very robust and durable and well-suited for rough gravel riding .

Conversion to tubeless with Trek’s TLR wheels is a breeze and is absolutely essential for a gravel bike. It further adds to the versatility of the bike and relieves your worries of pinch flats when you turn off the tarmac. Going tubeless also allows you to run lower tire pressures, which improves traction for off-road riding on loose conditions and provides a smoother ride for long distance adventure rides.

When I purchased my Checkpoint ALR 5 in 2018, Shimano had not yet released their GRX groupset, and the Checkpoint came equipped with a full Shimano 105 groupset. While this represented a great value back then, I felt it was a bit over-geared with a 50/34 compact crank, and I ended up swapping out my drivetrain when Shimano came out with the GRX.

Trek has since updated the Checkpoint ALR 5 and equipped it with a 2x Shimano GRX build, using the higher-end GRX 810 derailleurs. The crankset is a 46/30 with the same 11-34 cassette, providing more low-end gearing that is much more appropriate for off-road riding, especially for the casual gravel enthusiast.

The GRX groupset is, in my opinion, a huge success for Shimano.

I converted my Checkpoint to a 1x GRX 812 drivetrain and fell in love with the GRX 812 rear derailleur. The long cage derailleur allows me to run an 11-42 cassette with a 40t chainring upfront, further increasing my low-end gearing while still providing me the gears up high for pushing the pace on fast descents.

I am a big fan of 1x drivetrains, especially for off-road riding, so my 1x GRX 812 drivetrain has been a dream. The 810 level components are “Ultegra level,” for you roadies out there, but they are more robust for the bumps and vibrations encountered on mixed terrains. I never experience any chain slap, and the shifting is reliable, crisp and quick on any surface.

I can’t speak highly enough of the GRX 810 drivetrain, and I think it is outstanding that Trek offers such high-level components on an aluminum build at an affordable price point. The Checkpoint ALR 5 offers a high value build with its drivetrain selection without the added cost and pain associated with carbon frames.

The Shimano 105 hoods provide plenty of grip and control for my older Checkpoint, but I do wish I had the GRX shifters that now come stock!

Similar to the drivetrain, the Checkpoint ALR 5 was originally released with 105 shifters when I purchased the bike. The front of the hoods on these shifters is raised up high enough that I do not experience any issues sliding too far forward on the hoods when riding on rough roads.

Shimano has since improved on the hood design with the GRX line of shifters. They offer an excellent, raised stop for your hands. This provides even better control and stability off-road, and the GRX shifters now come standard on the Checkpoint ALR 5. While my 105 shifters still get the job done, I am admittedly jealous that I don’t have those robust GRX shifters !

• Lever: ST-RX815
• Lever Adjustability: reach
• Actuation: [brake] hydraulic, [shift] electronic
• Caliper: BR-RX810
• Mount Type: flat-mount

The Checkpoint ALR 5 also comes stock with hydraulic disc brakes. This is pretty standard for any gravel bike, but it is worth noting that the Checkpoint checks this box, as well, providing reliable stopping power, even in harsh conditions.

The saddle that comes on the Checkpoint ALR 5 is the Bontrager Montrose Comp. This saddle is surprisingly plush, when compared to a road saddle, and provides plenty of flex from its shell and central cutout. This makes it very comfortable for long rides, even on rough gravel, and I found it surprisingly comfortable out of the box.

Eventually, I swapped out the Bontrager saddle for my go-to, the Brooks Cambium C17. While the Bontrager saddle is very comfortable, I am a fan of Brooks saddles and like to use them on most of my bikes, especially for road and gravel riding.

The Brooks Cambium C17 is one of my all-time favorite saddles, so, of course, I had to put it on my do-it-all bike: the Checkpoint.

• C17 Cambium; Flexible and Robust Touring Surface.
• All Weather, durable and comfortable saddle that is “ready to ride”.
• Vulcanised Natural Rubber Saddle Top.
• UV + Abrasion-Resistant Waterproof Nylon Top.
• Tubular Steel Rails; Durable, Anodised Aluminium Rivets

The handlebars look a lot like cyclocross handlebars and, in fact, are the exact same bar that Trek puts on the Boone, their top-level cyclocross race bike. The bars are a standard width and do not feature any flare to the drops, something that is becoming more common on gravel bikes, but this maintains the more race-inspired feel that Trek was obviously looking for with the Checkpoint.

One nice touch for the handlebars is the gel padding included underneath the handlebar tape. This dampens vibrations in the handlebar and provides a nice reprieve for your hands and wrists over long rides. This small touch makes a big difference during long days on the road, and I’ve come to appreciate those little pieces of gel.

Where is the Checkpoint ALR 5 Lacking?

Only 700c wheels.

Trek claims that the Checkpoint can not accept 650b wheels; it can only use 700c wheels. I do find this to be a bit disappointing, honestly. Many other gravel bikes on the market, such as the Specialized Diverge, are similar to the Checkpoint but offer the added versatility of 650b wheels.

Running 650b wheels allows riders to increase their tire size for improved off-road control and softer ride quality. With 650b wheels, you can run 27.5” mountain bike tires at widths exceeding 2”. I think having this versatility is extremely valuable in a gravel build, and I do wish I could run a pair 27.5”x2.1” tires, as this would suit my riding style well.

More Race-Inspired than Gravel-Inspired

The Trek Checkpoint ALR 5 pulls a lot of design elements from their cyclocross line, perhaps too many. While the race-inspired geometry makes a roadie like me feel right at home on the bike, it creates a bike that is simply a good all-arounder.

The Checkpoint performs well on road and light gravel, but it can be challenging to ride on more technical off-road terrain due to its race geometry. When the downhills get steep and loose, the Checkpoint’s more aggressive ride position quickly becomes noticeable, and I sometimes find myself wishing I had a slacker set up.

The handlebars are also reminiscent of a cyclocross race bike or a road bike. It’s more common for gravel bikes to offer wider handlebars with flared drops that provide more control and stability for the rough stuff, but the handlebars on the Checkpoint do not offer that same stable feel when the roads turn especially rough.

The Trek Checkpoint ALR 5 truly is a great gravel bike. It offers excellent value with a high-quality build for your dollar. If you want to spend your money on high-quality drivetrain components and functional design, rather than dishing out cash on a carbon build that cuts corners on the components, then the Trek Checkpoint ALR 5 is for you.

The Checkpoint performs well on any terrain, but you may find it lacking in certain areas where other bikes excel. If you know you want to run wider tires for rough off-road riding or are interested in ultra-distance touring or bikepacking, there are better options on the market that will more fully meet your needs. Furthermore, if you aren’t a fan of race-inspired geometry and prefer more of an endurance bike feel, the Checkpoint is not for you.

The Checkpoint ALR 5 is a great all-arounder and can replace a couple of your bikes. Performing well on and off the road gives the Checkpoint potential to replace your quiver of bikes and be a contender for your one do-it-all bike. The Checkpoint ALR 5 truly fits the description of a “jack of all trades, master of none.”

Trek Checkpoint SL6 eTap long-term review: Simple done brilliantly

The trek checkpoint is the only bike you need to take you on every adventure.

Cyclingnews Verdict

If you can only have one bike, the Trek Checkpoint SL6 eTap is a serious contender. It’s the kind of bike that just works. You can upgrade it if you want to but you don’t need to. There are mounts for mudguards and bags, and with only a tyre change it will transition from a comfortable road bike to a capable off-road partner.

SRAM Rival AXS is the perfect groupset for an all-arounder

Mud-guard mounts

Mounting points for every bag you can think of

Non-proprietary seat-post provides options

Internal storage is convenient

Downtube protection eases worry

Threaded bottom bracket

Ideal all-around gearing

Short stem for added stability means handlebar/knee interference

Lacks included protection for the chain stay

Detail behind the fork steerer collects water and is difficult to clean

There's a cadre of people who get really far out into adventure riding that it's basically a small step away from needing a mountain bike. There are also lots of people who want the absolute fastest road bike available. Those ends of the spectrum don't represent the vast majority of riders though. Most people have a lot less focus and need a good, versatile bike that just works. We included the Trek Checkpoint on our list of the best gravel bikes available because that's exactly what you get, a bike that just works. 

The Trek Checkpoint is a bike that I have held onto for close to a year. It carried me across thousands of miles and all kinds of weather. I've had adventures on and off the road and I've put the bike to the test in every type of riding I could think of. After all this time, I'm ready to discuss the experience, what I like about it and where it falls short. If you've been considering a new gravel bike keep reading to see if the Trek Checkpoint is the right choice for you.

Design and aesthetics 

In many ways the Trek Checkpoint is a fairly uncomplicated design. The biggest standout design feature is the rear IsoSpeed decoupler system but even that piece, at least in the SL, sticks to the less complicated version. Trek refers to this version as the "seat tube IsoSpeed" and it refers, as expected, to the seat tube alone. There's no adjustment, nothing to think about, and just an isolation of the seat tube from the structure of the top tube and the seat stays. The end result is a passive suspension design that relies on flex in the 500 series OCLV carbon. 

To further exaggerate the effect, there's a prominent cutout near the bottom of the seat tube. The cutout doesn't reroute the tube for better aerodynamics but instead narrows the tube. The narrow point becomes the fulcrum and the rest of the tube has room to move around. If you want to add even more passive suspension, the non-proprietary round seat post means there's plenty of opportunity to take advantage of aftermarket seatposts. Something like the Ergon CF Allroad Pro Carbon seat post is an easy swap, further emphasising how uncomplicated the design of the Checkpoint is. 

There are a few other smart little design features as well. Details that continue to keep it simple but functional like the in-frame storage. Behind the water bottle mounts on the downtube is a lever that opens up a space at least as big as your typical flat repair kit. There's a bag that makes sure anything in the space doesn't rattle and the back of the door has room for the Bontrager Bits Multi-tool. 

On the other side of the down tube is where you'll find the carbon armour. This amounts to plastic cladding permanently attached to the lower section of the downtube. It's once again simple but important. Unfortunately, there's no matching armour on the rear chain stay but what you will find is a water bottle mount in the carbon armour. 

The under-the-downtube water bottle mount is just the tip of the iceberg when it comes to mounting points. There are two standard water bottle mounts, that one under the downtube, and an extra three mounting points higher up the downtube. If you aren't running frame bags that's room for an extra water bottle but there are also three mounting points under the top tube. The Bontrager adventure frame pack, on our list of the best bikepacking bags , will attach to the frame without straps using these mounting points. That still leaves an extra pair of mounting points on the upper portion of the top tube for a bolt-on top tube pack. 

The SL version of the Trek Checkpoints goes even farther with mounting options. While the SLR build gets the lighter 700 series OCLV carbon it also does with "only" the fourteen frame mounting points. Sticking to the SL models means there are also three extra mounting points on each side of the fork. Both models also have the option of fitting real mudguards and the Bontrager NCS Alloy Fender Set is one of best out there although there are also other options on our list of the best mudguards . 

Like the design features, the aesthetics of the Checkpoint differ a bit throughout the lineup. The top-shelf SLR 6, 7, and 9 are where you'll find the most colour options while lower down the line the ALR and SL models have only one or two colours depending on the specific build. In the case of the SL 6 eTap here, the only colour available is a deep red Crimson/Carbon Red Smoke that dips the bulk of the frame in a rich high-gloss blood red. There are metallic flakes throughout and a geometric pattern at the downtube and forks with a few details in a darker smoked red. 

The Trek Checkpoint lineup is extensive to the point of confusion. Right now, there are 12 different models listed with three frames serving as the building blocks. Serving as the entry-level models, the aluminium ALR frameset gives less expensive options with two builds before moving up to the carbon SL models. All using the same 500 series OCLV carbon, the SL models have three builds. These are less expensive than the SLR models but also focused more squarely on bikepacking with additional fork mounts. At the top of the lineup, the four SLR models switch to the lighter 700 series OCLV carbon and they also lose the fork mounting points. 

The SL 6 eTap that we spent our time with represents a middle-of-the-lineup option and costs less than half the price of the top model. The groupset is SRAM Rival AXS with 12 gears across a 10-44 cassette and a 40-tooth front crankset. The frame works with 1x or 2x but if you want a front derailleur you'll have to decide if you'd prefer to move up or down. Down drops to 11-speed GRX while up gets SRAM Force AXS Wide but also packages carbon wheels and represents a significant price jump. 

Instead of the carbon wheels on the more expensive SL 7 eTap, the 6 comes with the alloy Bontrager Paradigm Comp wheelset. While not a particularly high-end wheel these check all the boxes with a centre lock disc interface, 25mm internal width, and tubeless compatibility. Thru axles are standard bolt-through in 12x142 and 12x100 and the included tyres are Bontrager GR1 Team issue in a conservative 700x40mm width. There is space for up to a 45mm tyre if you find yourself looking for more off-road capability. 

For the touchpoints, expect Bontrager pieces. The saddle is a short nose Bontrager Verse Comp with steel rails and it's supported by is a 27.2mm carbon piece also from Bontrager. At the front of the bike the bars are the rather unique Bontrager Elite Gravel bars that we feature in our best gravel handlebars list. They have an integrated foam padding to help ease the rough roads and come paired with a shorter than standard Bontrager alloy stem.  

Performance

As a journalist who writes about cycling technology, I have an attraction to exotic tech in bikes. The new Trek Madone with a chunk missing from the seatpost sounds interesting. Or, if we are talking gravel, maybe a single-sided Lefty suspension fork like the Cannondale Topstone I previously spent time on. The wilder the better for me both because of my job and because that's my personality. 

The problem is that those kinds of bikes can be difficult to live with. The higher the integration and the more proprietary the pieces, the bigger the challenge. For example, the Lefty fork is amazing at what it does but if I want to drive to a ride with a friend I have to ask what kind of rack they have. If it's a fork-mounted version, then it won't work for me.

Then there's the Trek Checkpoint SL 6 eTap and its distinct lack of fancy technology. On paper, it's almost a boring bike but when people ask me for a bike recommendation, it's often my go-to choice. There are mounts everywhere, including for mudguards and it will do whatever you ask of it. I got the Checkpoint, added Garmin power pedals and swapped the saddle to an Ergon SR Allroad Core Pro, and proceeded to ride it for thousands of miles without ever having an issue. When winter hit, I added mudguards and rode through the winter spending seven hours at a time in constant rain every weekend. I never once had to mess with seat post issues or creaky bearings, everything just worked. 

I changed wheels and handlebars because I was testing things but the stock pieces were fine. The groupset in particular is a highlight and has become my gold standard example of why 1x12 might make sense for everyone. Rival has worked flawlessly and while 11-speed 1x gearing occasionally leaves me searching for gears, 1x12 has everything I need. The 40-tooth front and 44 rear works for climbing on loose surfaces, even with a loaded bike, but has plenty of gearing for road riding too. Every now and then I spin out when descending and chasing someone but it's rare and I prefer to have the climbing gears. 

When asked, I tell people you can walk out of the store with an SL 6 eTap and there's nothing you need to swap. The wheels aren't light, or fancy, but they work just fine. Same with everything else except the stem. One of the headline details about the Trek Checkpoint is the geometry that uses a short stem and a long wheelbase and right away I found it annoying. I swapped to the Trek RSL stem in a 100mm length as soon as possible. I noticed no lack of stability but I did stop banging my knees on every hill. 

Other than the stem, the Checkpoint has never left me asking for more. During the winter I would come home freezing and drenched with a bike caked in mud. I didn't wash the bike and at one point the brakes only alerted me to an issue when the pads ground down to the metal backing. Despite the lack of maintenance the groupset, wheels, and frame haven't needed anything. If I want to go bikepacking, I will never need to get creative with mounting. If I want to use the Checkpoint as a road bike, a tyre swap will have it ready to go. 

There are bikes that excel at a particular thing. You can get as specialised as you want in whatever area appeals to you and you can collect a quiver of bikes that you choose between depending on what's on the menu that day. Or you could get a bike like the Trek Checkpoint SL 6 eTap that just works no matter what you want to do. 

The Checkpoint might be a gravel bike but that's far from all it offers. Swap to a 28 or 30mm tyre for road riding and it's perfectly capable of keeping up with whatever group you want to ride with. If a summer gravel race catches your eye, swap on a 40mm tyre and only your legs will keep you off the podium. For a more relaxed pace bikepacking weekend, a 45mm tire might be a good option and you can load up all the mounts with every bag you can think of.

The only real question is which of the many build options makes sense. The SLR frameset is lighter but it's also a lot more expensive and it lacks mounting points on the fork. The SL 5 build gets you all the mounting points at a lower price but it’s also an 11-speed mechanical build with narrower wheels. If you are looking to save money look to the aluminium frameset options and if you've got a bit more money to invest, the Trek Checkpoint SL 6 eTap represents a do it all bike that balances price and performance.

Trek Checkpoint SL 7 gravel bike review: a true all-terrain vehicle

Trek's 'Adventure focused' lives up to bikepacking expectations, with stable geometry and practicality

• Sign up to our newsletter Newsletter

The Trek Checkpoint SL 7 is an outstanding all-rounder when it comes to all-terrain riding. A true ATV, the Checkpoint provides a planted, confidence-inspiring ride feel which is great for tackling more technical terrain. It might not be as supple as the likes of the Cannondale Topstone, but if long-distance trekking on tough terrain is your bag, the Checkpoint SL 7 is right on the money.

Planted ride feel

Compliant frameset

Handles luggage weight very well

In-frame storage is genuinely useful

Rugged ride feel won't be for everyone

• Value and conclusion

Gravel riding is a discipline that holds a vast range of different bikes within its sphere, from gravel race bikes, to do-it-all rugged machines. Trek markets the Checkpoint SL range as its 'Adventure-focused' line, and I think they've got it spot on.

Having tested the Checkpoint SL on everything from roaming local trails to an overnight bikepacking excursion (fully laden with camping gear) I can confirm that if you are on the hunt for your next adventure gravel machine, then the Checkpoint SL 7 might just be one of the best gravel bikes on the market.

Trek Checkpoint SLR 7: Frameset

Since its last iteration which came out all the way back in 2018, Trek has given the new Checkpoint platform some serious revamping. The tubes are much chunkier now, giving the bike a much more industrial aesthetic. 

Trek still includes an 'IsoSpeed decoupler' at the seat stay junction - this is a pivot system, similar to Cannondale's 'Kingpin' which allows the seat post to flex fore and aft. This, alongside a standard 27.2mm seat post, is designed to give the bike some extra compliance where the rider will feel it most. Though, I found it doesn't offer quite as much real-world travel as the Cannondale equivalent.

One big change over the last iteration is the extinction of 'Stranglehold'. The system enabled chain stay length adjustment of up to 15mm (and single speed conversion!), which meant riders could alter the geometry between a slightly more stable ride (with longer chainstays), or a more playful one (shorter chain stays).

27.2mm carbon seatpost and ISO speed help compliance

Trek has opted for 435mm chainstays across all models - 10mm longer than the previous shortest setting. This does change the ride feel, which I will get onto, making for a more stable feeling rear end. Once again this characterizes the Checkpoint SL at the more adventure end of the gravel riding spectrum .

The in-frame storage is perhaps the most radical part of this bike's dedication to long-distance riding, and It works well. A section of the frame underneath the bottle cage on the downtube can be quickly released via a small lever, revealing room for a tool roll, and spares. While the 'boot capacity' is nothing overwhelming, it does provide a neat place to hide away annoying spares, like the odd tube, or smaller mini-pumps .

In-frame storage for tools

Trek has also included a plethora of mounting points - three bosses can be found on each fork blade, and the bike even holds the capability to mount a rear rack, which I think is a very underrated option for modern-day bikepacking, even if it isn't the most trendy. As well as these options, the usual suspects can be found with mounting points on the top tube, and underneath the down tube as well.

Notable too is the tire clearance. The new Checkpoint SL is good for 45mm tires when coupled with a 700c wheelset, but this can be upped to a 2.1 inch (53.3mm) for those who like the playful handling of a slightly smaller 650b wheelset. For the rough, and extremely varied terrain in my local testing ground, this too offered some much needed ride forgiveness.

Trek Checkpoint SLR 7: Components

The full Trek Checkpoint SL line-up spans a price range from $3,399.99 / £3,700.00 with the SL 5 to £6,400 with the SL 7, which is the model I had on test. This may be the top of the range for the 'SL' frameset, but it's worth noting with the SLR framesets, builds are priced as high as $12,249.99 / £12,000.00.

Nonetheless, the Checkpoint SL 7 still boasts some pretty high-performance parts, starting with the dependable SRAM Force AXS groupset . Trek opts for a two-by setup rather than a one-by system, which I think, for most consumers, will still be the better option. 

43/30t chainrings coupled with a 10-36t cassette provide a wide range of gears, which is great news for long-distance riders, especially those who carry luggage and this never left me feeling under, or over-geared.

Sram Force AXS groupset throughout

The checkpoint SL 7 rolls on in-house component brand Bontrager Aeolus Pro 3V carbon wheels, which feature a 25mm internal rim width and a particularly loud freehub.

Though both the wheelset, and provided Bontrager GR1 tires are both tubeless-ready, the SL 7 comes out of the box with tubes to get started. Although I didn't set up the tires tubeless, it should be pretty easy, especially with a full Bontrager system. Bontrager provides rim strips, which snap into the Aeolus wheels, and are designed to work with Bontrager tires, meaning tight tolerances can be adhered to throughout the product range.

The finishing kit is a fairly standard affair, which can leave a little to be desired from a price standpoint, but then again it should be fairly robust. You do get Bontrager's carbon 27.2mm seat post, but both bars and stem are an alloy affair, with the 54cm frame on test coming stock with 420mm (center to center) bars, which are slightly flared, and a -7 degree 80mm stem. 

Trek Checkpoint SLR 7: The ride

As I mentioned all the way back in the intro, this bike got a jolly good reviewing. With gravel bikes often marketed as the 'do-it-all' bike option, I always see fit to test gravel bikes on a whole host of terrain.

I treated the Checkpoint no different, treating it to a heap of different obstacles. My first ride was a shorter blast around a local test loop, which encounters everything from fire road to steep single track and even some small jumps. This loop allows me to gain a pretty good tell on a bike's character from the off, and it is fair to say the Checkpoint certainly lies at the more stable end of the spectrum.

The Checkpoint handled all the terrain perfectly well, but offered a more straightforward ride characteristic when compared with a more flamboyant handling bike like the Cannondale Topstone Carbon 3 . For those who like a more dependable ride, this will be great news, but as someone whose riding is catered to a more playful experience, the Checkpoint wasn't quite so up my street. 

Bikepacking setup for a real test

Longer rides, and in particular, bikepacking , is where this gravel machine truly comes alive. I took the SL 7 on a (shortened due to illness) one-night trip around the Isle of Wight during testing, and this really allowed me to get to grips with the bike when fully burdened with all the equipment needed for a rough night's sleep away from home. 

The bike remained totally balanced even when loaded up with a saddle pack, frame bag, and bar bag. The in-frame storage too was super useful - as previously mentioned it might not be a huge amount of real estate, but in practice, I found it was just enough to stop me from sacrificing a heavier base layer as I was able to stow away multi-tool, mini-pump, and a tube all in the tool roll. At 8.9kg too, this does make a great bikepacking platform, being rugged whilst not carrying excess weight.

When it came to the steep ups and downs synoptical with the Isle of Wight, the Trek did not falter - in the same breath however, it did not blow me away. While the chunky tubing provides great power transfer and a truly robust feeling ride, I found the ride quality to lack the excitement of other gravel bikes I have tested. The best comparison is the Cannondale Topstone Carbon 3, which, though a heavier bike, at 9.22kg, actually feels lighter and more supple than the Checkpoint.

That said I did feel like I could throw the bike at absolutely anything, loaded up with gear or not, especially with the slightly flared bars, which offered great control.

Tire clearance of up to 45mm

For me, this comes down to geometry, and it is a double-edged sword. The Checkpoint, with longer chain stays than many of the best gravel bike contenders, is undoubtedly a more stable and planted ride - and some consumers will love the imposing ride feel this brings, but for others who favor a more supple ride quality, it might not be the bike for you.

It is important to note though, this is not a criticism, much more a characterization of the bike. As gravel riding spans such a wide spectrum, it is essential to consider what riding you prioritize, and what characteristics you want out of a gravel bike.

Trek Checkpoint SLR 7: Value and conclusion

Value aside, the Trek Checkpoint SL 7 is probably the best gravel bike I have ever tested when it comes to bikepacking. An unbeatable ride feel, especially when loaded, made for super easy riding on any sort of terrain, even when tiredness loomed heavy at the end of long days of riding. We tested 9 off-road machines to crown our gravel bike of the year , with the Trek Checkpoint SL 7 winning our 'best expedition bike' title. 

Include value too ($6,699.99 / £6,400.00 for the SL 7 we tested), and I think Trek is still on the money, but equally not groundbreaking. The most obvious competitor to the do-it-all Checkpoint is the Specialized Diverge Expert Carbon, which retails for a very similar $6,200.00 / £6,500.00. For a similar price, specialized matches the spec pretty much to every dotted T, also featuring carbon wheels, a second-tier SRAM AXS groupset (albeit one-by SRAM GX AXS), and alloy finishing kit.

There are certainly better value bikes out there though - the Giant Revolt Advanced Pro 1 for example, which won our overall best gravel bike of the year retails for $5,500.00 / £4,899.00, which is considerably more palatable than the SL 7. You do only get SRAM Rival AXS at this price point, and it doesn't feature the same number of mounting points if out-and-out exploration is what you are looking for, but it is still worth considering.

The 2023 Trek Checkpoint SLR 9 eTap in review – Our big gravel race bike shootout

At € 12,999, the Trek Checkpoint SLR 9 eTap is the most expensive bike on test. It promises to be a bike that can do it all, with added compliance at the rear, and the most feature-rich frame. But can the high price tag be justified, and how does it compare to the competition in our 2023 gravel race group test?

This bike was reviewed as part of our 2023 gravel race bike shootout. You’ll find a comprehensive group test and test field overview here: Which is the best gravel race bike of 2023? 9 gravel race bikes in review

As one of the world’s largest bike brands, Trek have access to nearly inexhaustible resources. The Checkpoint incorporates all the brand’s know-how and promises to be a gravel race bike par excellence. Originally designed for long rides on everything from asphalt to rough gravel, the Checkpoint has gradually evolved into a gravel race bike over the years. It still has a clear focus on long-distance comfort and therefore comes equipped with Trek’s IsoSpeed system for more compliance on bumpy terrain. But how does the bike compare to the Canyon Grail CF SLX 9 eTap and Berria Belador Allroad 8? These two bikes also feature damping elements that go beyond the inherent flex in the frame. Can the Checkpoint SLR achieve the promised balance, combining comfort with that race bike feeling? How much value for money can the most expensive bike on test offer at just under € 13k? Do you really get more than with the Canyon Grail, which costs less than half as much?

Trek Checkpoint SLR 9 eTap – A true all-rounder or a jack of all trades but master of none?

The Checkpoint isn’t the lightest, fastest, or the most comfortable bike. Instead, Trek’s aim is for it to perform well in all conditions, which should make it the best all-rounder, capable of dominating all disciplines. It’s designed for stability and control, comfort, and functionality, placing little focus on aerodynamics and weight savings. Surprisingly for a bike in this price range, it doesn’t feature a fully integrated cockpit. In contrast, the internal cable routing has been very cleverly solved. A neatly integrated rubber cover encloses the cables and prevents the ingress of dirt, unlike on the Argon 18 Dark Matter. The convenient storage compartment in the down tube has a multi-tool hidden in the lid, and the compartment is big enough for more than just a spare tube.

Specific Features

active damping thanks to IsoSpeed storage space in the down tube protected downtube generous tire clearance

To drive the rear wheel, Trek rely on the flagship SRAM RED eTap AXS groupset, using a 1x setup and featuring a power metre – you wouldn’t expect anything less for the price. The 45 mm tire clearance is above average in our test field and appropriate for a gravel race bike. The 40 mm Bontrager GR1 Team Issue tubeless ready tires, however, couldn’t deliver. Fitted to skinny rims, the tires inflate like balloons and tend to bounce. In addition, the tread pattern isn’t good at self-cleaning and quickly reaches its limits on loamy soil. Visually, the Checkpoint is a low-key bike with round and voluminous tube shapes. It relies on understatement. The discreet paint job and restrained look don’t look like a € 12,999 bike. That said, you can customise the bike with the Trek’s Project One configurator, allowing you to design your very own, one-of-a-kind colour scheme.

Trek Checkpoint SLR 9 eTap – Compliant long-distance racer?

Despite the understated looks, the Trek Checkpoint SLR 9 eTap is a high-tech bike. One that is more comfortable thanks to the IsoSpeed system in the rear. The decoupled seat mast of the IsoSpeed system effectively absorbs small bumps, such as on woodland paths, and it doesn’t bounce back uncontrolled. It is very subtly integrated into the frame and doesn’t stand out. Unfortunately, there’s an imbalance in comfort between the front and rear. The front end is rigid and offers minimal compliance. We would have liked a little more compliance up front, especially for long distances. To complicate matters, Trek decided to fit a round handlebar. Sure, the Checkpoint isn’t an aero bike, but gravel bikes also benefit from the comfort of oval shaped tops, and it’s something we no longer want to do without. The riding position is neither upright nor aggressive, fitting for a comfort-oriented gravel race bike. It’s similar with the handling: it offers pronounced straight line stability but is slightly lacking in agility, which has a negative influence on the handling in technical terrain, whether you’re riding uphill or downhill. On the other hand, the bike excels on fast descents with long, open corners.

A bike with a trunk that looks slower than it is.

The intuitive steering is easy for beginners to get to grips with. Thanks to the light wheel and tire combination and the fast-rolling tread pattern of the tires, it’s very responsive and loves sprinting. Here, it pays off to opt against having flex in the frame. By limiting the compliance to the IsoSpeed seat mast, the frame can be designed to be stiff and direct, keeping power transfer losses to a minimum.

Who is the Trek Checkpoint SLR 9 eTap for?

As a premium bike brand, Trek promise a lot with the Checkpoint SLR 9, and they deliver, too. However, it’s positioned as a bike for a less athletically ambitious target group. Like the Canyon Grail, the Checkpoint isn’t made for fast gravel races, performing best on relaxed weekend trips and forest service ways. If you’re out to rack up kilometres and avoid technical trails, the Checkpoint is the bike for you and is sure to put a smile on your face. The optional bikepacking equipment also makes it an ideal companion on big off-road adventures. This is where the Checkpoints racing ambitions lie. It can play to the strengths of its versatility and integrated damping on multi-day events and long self-supported races. However, it will need some tuning before you head off. A more compliant handlebar and more grippy tires will make the Checkpoint a high-performance bike.

Tuning tips: A handlebar with flattened tops and more compliance as well as tires with more grip and cushioning.

Conclusion on Trek Checkpoint SLR 9 eTap

Due to its components and the imbalanced comfort between the front and rear, the Trek Checkpoint SLR 9 eTap isn’t entirely convincing as a gravel racer. The do-it-all approach doesn’t make it feel like a race bike but rather like a bike for tech fans, which is further emphasised by its cutting-edge features. However, the comfortable rear end helps the Checkpoint perform well on long distances, making it a viable choice for multi-day rides together with the optional bikepacking kit.

• IsoSpeed system is inconspicuous and functional, providing added comfort at the rear

No, it’s not about perfect race tracks, it’s about efficiency. Fast, fleet-footed and efficient – those who want to speed along high-speed passages need a defined and spritely bike that accelerates with ease and efficiency. Nevertheless, reliable components are important too. We interpret “Smooth tarmac” bikes as follows: Hard efforts at high speeds with a maximum efficient bike on a consistently well-paved road. Effort-joy ratio: 80:30 (not everything has to be 100%!) ↩

… also known as bike riding. Broken-up roads in the hinterland, deadlocked gravel roads, loose surfaces – sometimes muddy, sometimes bone-dry. For this, it takes bikes with super all-round, handling and wearing qualities uphill and downhill. Effort-joy ratio: 50:50 ↩

If you want to use your bike almost every day, you usually do not need an extremely tuned racing machine. Solid components, which are able to cope with the rigours of continuous usage in any kind of weather, are part of the basic equipment. At the same time, the bike should have practicable details: integrated fenders/assembly options, luggage racks/attachment points and a light system or at least the option of installing bike lights. The position on the bike should be rather relaxed, the overall comfort high, so that the Afterwork Ride becomes a cure and not a curse. Effort-joy ratio: 30:70 ↩

The New Trek Checkpoint Line Is For Gravel Riders of All Kinds

Updated geometry and differentiated models for speed, adventure, and all purpose riding

The Takeaway: A great bike gets better, with geometry updates suited to the evolution of gravel.

• Two centimeters longer reach and front center on all sizes
• One centimeter longer chainstays
• New race-oriented SLR platform
• Additional cargo mounts

Price: $12,000 (SLR 9, as tested) Weight: 17.8 lb. (Size 54cm)

Trek’s gravel loving Checkpoint is all new front to rear, with new geometry (covered below) and features for the ever-evolving world of gravel riding. That evolution is why Trek differentiated the three complete bike platforms—SLR, SL, and ALR—for different kinds of gravel riders. I go into more depth below, but the short version is: SLR = race; SL = all-around, ALR = utility.

Threaded T47 bottom brackets now grace all Checkpoint frames, but Trek has done away with the sliding dropouts found on the previous generation Checkpoint. All eight builds get gravel gearing and clutch-style rear derailleurs (Shimano GRX or SRAM eTap AXS), as well as 40mm tubeless ready tires and tubeless ready rims. All models, and all sizes, can fit up to 45mm tires with plenty of mud clearance; which means riders in dry conditions can fit in even bigger tires. If you choose, you can fit the Checkpoint with 650b wheels—all models and all sizes come stock with 700c wheels—which bumps tire clearance up to 53mm (2.1 inches).

In the press release, Trek makes mention of “ Émonda -inspired aero tube shapes,” without providing any wind tunnel data. My suspicion is the tube shapes do save a few watts, though Trek isn’t leaning into gravel aero as much as 3T does with its Exploro RaceMax .

Trek Checkpoint — Geometry

Geometry is where the new Checkpoint sees the biggest change. While there are three Checkpoint frame platforms (outlined below), all three share the same, all new, geometry (see table above).

The overall theme to the geometry updates is “more progressive.” Trek took a page from the mountain bike playbook and stretched all sizes of the frame’s reach and front center by about two centimeters. Trek now fits shorter stems and shorter-reach bars to mitigate cockpit length changes. Chainstays on the frame grow by a centimeter (now 435mm on all sizes). Trail is also longer (about six millimeters) even though head angles remain about the same—new fork offset is 45mm, old was 49mm—and wheelbase grows as well. Frame stack bumps up a touch too.

Jordan Roessingh, Trek’s director of road product, says the new geometry aids stability, “It’s a longer bike, so whether you’re doing long Unbound type stuff where you’re just pointing the bike straight or you’re doing high speed stuff on gravel descents in the mountains, we believe this geometry lends itself to confidence. Getting that wheel out in front of you also unweights it makes you feel a lot more confident when you’re doing steep technical stuff—you don’t feel like you’re going to go over the bar. That front wheel is really easy to unweight and allows it to roll over a lot more stuff.”

Roessingh further explained that the new geometry also reduces toe overlap on smaller sizes and allows them to approve larger tires sizes for smaller riders, “On the previous [Checkpoint] we had to limit our small frame size tire size recommendations to only 40mm. Not because the frame didn’t have the capacity for 45, but when you put a 45 it created too much toe overlap.” The issue here was government regulations that outline a production bike’s maximum tire overlap. But with the new bike’s longer front end every size can, officially, run up to a 45mm tire.

One note on the geometry: The new Checkpoint is not suspension fork corrected. However, the Checkpoint has a 1.5-inch lower fork steerer diameter, so you can fit the new RockShox Rudy , a Suntour GVX, or Fox AX, but doing so will raise the front end and slacken its angles.

Trek Checkpoint — Where is the Front IsoSpeed?

One surprising omission from the new Checkpoint is IsoSpeed in the front, a feature found in Trek’s Domane all road bikes . According to Roessingh, IsoSpeed on the front of a bike with big tires, “Doesn’t provide a sufficient gain in compliance to make a real difference to the rider because a [larger than 32mm tire] is such a dominant aspect of the compliance,” so it was left off the new Checkpoint. The benefit is a less complicated front end, and some weight savings.

Rear IsoSpeed continues on all models. Roessingh explains that it has more deflection than front Isospeed so it offers additional compliance benefit even with larger tires.

Trek Checkpoint — Three Frame Platforms

The new Checkpoint comes in three platforms: SLR, SL, and ALR. The top of the line SLR (super light race) platform is new to the Checkpoint line. Previously, Checkpoint topped out with the SL model. All the models have T47 threaded bottom bracket, internal hose and housing routing, 45mm tire clearance, frame bag mounts, fender mounts, and come in six sizes: 49 to 61cm. SLR and SL carbon frames get the same in-frame storage system found on carbon Domane frames.

But though the three platforms share geometry and many features, they’re tuned to suit different riders.

The SLR is race oriented, so it gets the highest-grade carbon composite, a traditionally shaped (not flared) road bar, and forgoes cargo mounts on the fork. This model also has Trek’s no-cut seat mast with (non-adjustable) top tube IsoSpeed.

The SL gets an all-purpose gravel focus. It uses lower grade carbon than the SLR but adds adventure riding features like three-pack mounts on the fork legs, and a flared gravel bar. This model does have Trek’s IsoSpeed decoupler in the seat tube but fits a traditional 27.2mm seatpost: That makes this model dropper-post compatible.

The aluminum framed ALR is the least expensive of the new Checkpoints, and Trek’s representatives expect this to be a popular model with riders looking for a commuter or utility bike. It has the same geometry as the other platforms, and the same rack, fender, framebag and mudguard mounts as the Checkpoint SL, and it gets a flared gravel bar and 27.2mm dropper-post compatibility. The two features it lacks relative to the SL are the in-frame storage and an IsoSpeed decoupler.

Trek Checkpoint — Ride Impressions and Review

Trek sent me the top-of-the-line SLR 9 eTap AXS well ahead of the bike's launch, and I’ve done my usual “gravel” shenanigans on this bike—long gravel rides, mixed media rides, some road riding, and plenty of singletrack.

On anything dirt, and especially on singletrack, the new Checkpoint is not just better than the previous generation, it’s one of the best gravel bikes I’ve been on. I love the previous generations above-average comfort and smoothness and that’s still present, but the geometry updates make the new bike much more capable: And the faster and more technical the dirt, the more the geometry pays off. It’s accurate, but not darty, and composed but appropriately flickable.

Here’s the rub: Give us geometry that lets us go faster and…we’re going to go faster. The Checkpoint is so damn fast on downhills singletrack that I take issue with Trek’s decision to forgo front IsoSpeed or correct the geometry for a suspension fork. I mean, this is a pretty compliant bike overall, but when you go faster the hits get stronger. Many times I wacked stuff that made my hands and arms stung. Bigger tires help, but a 45mm maximum isn’t that big (Canyon’s Grizl fits 50s, for example).

Basically, there were times I felt like the geometry was writing checks the Checkpoint couldn’t cash without some help from suspension. But then, when you add weighty suspension and fatter tires, you have a much different bike; so I’m also not sure that’s the answer. I think we’re at a very interesting point with “progressive” gravel bikes where they are tickling the edges of mountain bike capability and, if they go much further, suspension must be a part of the conversation.

On the flip side of the new Checkpoint’s added capability, it feels less chipper on paved surfaces. The old Checkpoint was almost a road bike that could do gravel while the new one definitely takes cues from the world of mountain bikes. On balance, this works out okay for the most fun and challenging parts of gravel rides, though the Checkpoint bike feels a bit logy on the liaisons between the best bits. That’s a compromise I’m okay with, but if you want more quickness on pavement from your gravel bike you might be happier on something like a Cervelo Aspero 5 or the 3T Exploro Racemax .

Trek isn’t breaking any new ground with the Checkpoint’s geometry and handing traits. This mountain bike influenced longer, more stable, geometry (oh, hello, Chamois Hagar ) is an increasingly popular trend, and already found in bikes like Canyon’s Grizl (which the Checkpoint reminds me of) and some other bikes. I’m curious to see how this geometry goes down with the general riding public, and how far brands push the geometry. When used for actual gravel and off-pavement riding and racing, this geometry makes sense. But if riders are buying gravel bikes because they want more capability and comfort out of a drop bar bike, but are mostly sticking to pavement, I don’t think this geometry suits that kind of rider.

Handling covered, let’s look at the rest of the Checkpoint’s attributes. The added cargo options (in frame storage, direct mount bag in main triangle) are great, almost mandatory, features for a gravel bike. My 54cm frame did have two water bottle mounts on the downtube, but it required a bit of trial and error with a Wolf Tooth B-Rad base to get two bottles to fit comfortably. With the Bontrager frame bag mounted, I needed to reposition the seat tube cage location to fit a bottle. Larger sizes have more space in the main triangle, so this won’t be an issue, but riders on frames smaller than 54 might need to look into alternative ways to carry water if they run the frame bag.

I do have a gripe with the road-bend bar on the SLR models. Trek sees this model as appealing to racers who are coming from a road background. This is why it gets a traditional, and lighter, road bar. But it’s still a gravel bike, and flared drops are awesome for comfort and control. Besides, flared bars are so awesome that once you ride them, you’ll want to put them on your road bikes. Thankfully, Trek didn’t do anything weird with the bar and stem on the new Checkpoint, so riders can fit anything they desire.

That’s my only gripe though. I love this bike, and the rest of the parts kit is dialed. I’m going to throw out special kudos for spec'ing the SRAM-equipped SLR models with power meters from the factory. I think that’s perfectly in line with this bikes purpose and customer.

Overall, the new Checkpoint is a wonderful gravel bike. It’s faster, better handling, and more suited to the needs of the today’s gravel rider.

Trek Checkpoint dives headfirst into the red-hot gravel bike market

Heading out the door? Read this article on the new Outside+ app available now on iOS devices for members! >","name":"in-content-cta","type":"link"}}'>Download the app .

After tentatively dipping its toes into the red-hot gravel waters last year with the lukewarm Domane Gravel, Trek is now being anything but tentative with the new Checkpoint family. The new carbon fiber and aluminum frames feature dedicated geometries, a slew of gravel-specific features, and Smart spec across the board.

Much of the U.S. CyclingTips staff has already spent the last couple of weeks on the new Checkpoint, and there’s no sense in beating around the bush: if gravel is your gig, this thing is not only good, but also seriously good fun.

What makes the Checkpoint a “gravel bike”, anyway?

It took the bike industry a few years to settle on a widely accepted definition of what a gravel-specific bike actually is, and admittedly, the differences are subtle. But there are genuine distinctions nevertheless, and the Checkpoint isn’t just a Domane endurance bike or Boone/Crockett cyclocross racer wearing different clothes. Indeed, there’s space in between those shades of grey, and the Checkpoint seems to color it in nicely.

Frame geometry is closest to that of Trek’s Boone/Crockett cyclocross cousins, with virtually unchanged wheelbase and reach, the same chainstay lengths, and nearly identical stack heights and head tube angles across the size range. Stability on loose surfaces is often a highly desirable trait for gravel bikes, though, so Trek has dropped the bottom bracket an extra 8-9mm relative to the Boone, depending on size. That may not sound like much on paper, but geometry geeks will confirm that it’s a substantial difference.

Quite interestingly, however, Trek is not prioritizing stability above all else on the Checkpoint.

As already mentioned, the wheelbase and chainstay lengths are roughly the same as the built-for-cyclocross-racing Boone, and the nearly identical stack and reach offers a similarly aggressive fit. But Trek has equipped each Checkpoint front-end with more fork rake — and, subsequently, less trail — which will actually make the bikes more responsive to steering input, not less. Trek’s philosophy here is that while the Boone is meant to be ridden primarily off-pavement, the Checkpoint is designed for a wider range of applications, and the combination of a nimbler front-end and lower center of gravity will make for more versatile handling.

That said, Trek also understands that different riders will want different handling traits. To address that, sliding “Stranglehold” dropouts on every Checkpoint — aluminum or carbon — allow for an extra 15mm of chainstay length. The shortest position will provide the handling characteristics described above, but extending the rear end up to a 440mm chainstay length will certainly mellow things out. Those sliding dropouts will allow for easy singlespeed setups, too.

Most importantly, Trek has graced the Checkpoint with the legitimately generous tire clearance that was lacking in the Domane Gravel. Whereas that stopgap maxed out at a modest 35mm, the new Checkpoint will swallow tires up to 700x45c, which is particularly impressive given that the chainstays are the same length as the Boone and Crockett.

Credit for this feat goes to the dropped driveside chainstay, which takes a dramatic detour down around the chainrings to create some extra space. Trek may not have come up with this concept — Open debuted the same idea on the original UP in 2016 — but it’s effective nonetheless.

Regardless, fans of Road Plus wheel-and-tire setups will be disappointed to hear that while they might fit, Trek doesn’t recommend using them on account on the already-low bottom bracket.

Up top on carbon Checkpoints is yet another iteration of Trek’s IsoSpeed “decoupler” at the seat cluster, comprising a pivoting axle system that allows the semi-integrated seatmast to flex more over rough terrain than a more traditional fixed junction would. Aluminum models unfortunately do without.

In terms of other features, however, Trek has stacked the deck on the Checkpoint.

Larger frame sizes (56cm and up) can fit three water bottles inside the main triangle (with room for a frame bag in some configurations), and there’s an additional mount on the underside of the down tube. Rack and fender mounts are standard as well, and bosses on the fork blades can be used for even more bottles, or Trek’s own 720 lowrider rack system. For easier on-the-go access, yet another set of bosses on the top tube (carbon Checkpoint models only) are positioned for any number of popular “Bento Box” bags.

The stock stems come with a selection of Bontrager’s tidy Blendr integrated light and computer mounts, too.

Other highlights include internal cable routing, BB90 or PF86 press-fit bottom brackets (depending on the model), integrated chain-catchers, 12mm thru-axles and flat-mount disc brakes throughout, and generous armoring on the underside of carbon models.

Claimed weight for a 56cm carbon Checkpoint frame is a respectable 1,240g, plus 470g for the matching all-carbon fork. Aluminum Checkpoint frames tip the scales at 1,570g (claimed), plus 600g for the carbon-and-aluminum fork.

It’s common these days for bike companies to mix-and-match components to hit desired price points, but Trek has instead opted for full Shimano groupsets and proper hydraulic disc brakes across the board, even on the least-expensive Checkpoint ALR 4. According to Trek, it was more important to provide Checkpoint users with a consistently high-quality experience than to save a few pennies, and while buyers on more modest budgets will naturally have to content with some additional weight, it’s good to know that shift and brake performance will change little across the model range.

All Checkpoint models will also share the same wide-range gearing, with compact 50/34T chainrings matched to 11-34T, 11-speed cassettes. This should provide ample ratio options for most users, although it’s worth noting that riders looking to load their Checkpoints down with heavier loads might quickly find their bikes overgeared on climbs. Rumors have been circulating for some time now that Shimano is about to introduce chainring options that are more gravel/adventure-friendly, but it appears they’re not quite ready yet.

The new sub-compact and the future of wide-range gearing

In a nod to the varied terrain on which Trek anticipates Checkpoint buyers will be riding, stock bikes will all come outfitted with 35mm-wide Schwalbe G-One tires — one of our favorite mixed-surface treads, and a bold move from a company that also has its own tire brand. Those tires will all come mounted to tubeless-ready Bontrager wheels with internal widths ranging from 17.5 to 19.5mm, although the requisite rim strips, valve stems, and sealant aren’t included. Only the Checkpoint SL models will have tubeless-ready versions of those Schwalbe tires, too; ALR owners will have to buy those as well if they want to go tube-free.

Interestingly, Trek has passed over the flared handlebars found on many gravel bikes these days, instead opting for standard road bike shapes. Some hardcore gravel aficionados may protest this decision, but it nevertheless seems like a wise choice given the diverse user base that Trek anticipates for the Checkpoint.

For now, Trek is capping higher-end Checkpoint options to the SL 6 model, built with a mechanical Shimano Ultegra groupset. Might we see fancier SLR versions in the future, or ones equipped with electronic drivetrains? Perhaps, but that will likely depend on how this initial introduction goes.

Trek will offer the new Checkpoint in six aluminum and four carbon models, including versions for women with dedicated spec. Checkpoint will also be available as bare framesets in both the carbon fiber and aluminum versions.

Retail prices for the complete bikes range from US$1,700 for the Checkpoint ALR 4, up to US$3,800 for the top-shelf Checkpoint SL 6. Gravel riders who would prefer to take the DIY approach can pick up the Checkpoint SL frameset for US$2,000, or the ALR version for just US$960.

Checking out on the Checkpoint

Three CyclingTips editors — myself, Neal Rogers, and Caley Fretz — have been racking up time on the top-end Checkpoint SL 6 over the past few weeks, and one word has consistently been coming up in our conversations about how the bike rides and feels: fun.

The lower bottom bracket and zippier front-end seem like a contradiction at first, but in practice, it works very well. The Checkpoint is nimble and agile, but thanks to that ground-hugging center of gravity, still feels stable when sliding through loose corners. It’s in no way jittery, and in fact, feels notably planted and composed.

That curious geometry also makes the Checkpoint feel more road bike-like when pounding the asphalt, and certainly less cumbersome relative to some longer-and-slacker gravel options on the market. We haven’t had the opportunity to switch to lighter-and-narrower tires just yet, but initial impressions are that the Checkpoint would be well-suited to that role.

Heading on to more demanding terrain highlights the effectiveness of the IsoSpeed mechanism. While the 35mm-wide tires and relatively spacious rim beds obviously provide most of the cushioning, you can still feel — and see — the effect that IsoSpeed has on seat tube flex. It’s still a bit disappointing that Trek didn’t include IsoSpeed up front as well (as on the Domane SLR endurance road bike ), but the overall ride quality is still remarkably comfortable.

The stock 35mm-wide Schwalbe G-Ones provide reasonable float on softer surfaces, and still feel quick enough on harder ones. As promised, they’re a good compromise for the varied use the Checkpoint is likely to see, but I still wish Trek had been a bit bolder in this area. Having spent ample time on the 40c version of the G-One, I found that version to feel just as quick on asphalt, but provide better grip off-road. Granted, everyday riders might not share that progressive a viewpoint when it comes to mixed-terrain tires, however, so Trek’s conservative decision is perhaps the smart one.

All three of us have universally applauded the generous array of accessory mounts, which let users tune their setups to suit their own particular needs. Some might find the “Bento Box” bag to rub their legs when riding out of the saddle, but the beauty of the Checkpoint system is that it gives users the choice to outfit the bike however they see fit.

While the handling of the Checkpoint seems spot-on, the front triangle could use a bigger dose of torsional rigidity for better predictability — a complaint I also noted on the recent review of Trek’s second-tier Madone aero road bike frameset . The softness likely contributes to the Checkpoint’s overall comfort, but that propensity to occasionally wind up, and then release, under side loads can be occasionally off-putting. It’s reasonable as is, but may be a bigger issue when the bike is heavily loaded.

As is, total weight of a 52cm Checkpoint SL 6 is 8.85kg (19.5lb), without pedals or accessories – not exactly svelte when judged against dedicated road bikes, but competitive for the class.

Setting the mood

Overall, though, Trek seems to have done a very good job on the Checkpoint, and all three of us have mentioned that it’s a bike we wouldn’t mind having in our own personal stables. I’ve always believed that the tenor of rides is strongly influenced by the style of bike you happen to be riding at the time. Conveniently for us, Trek didn’t have editors fly to some far-off location as is often the case for bike launches; instead, Trek brought the bikes to Colorado, and we not only rode on routes that were very familiar on that first day with the Checkpoint, but with people with whom we’ve ridden on countless occasions.

These sorts of rides are almost always the same: they start out tame, the speed steadily ramps up, and by the time it wraps up, the bunch has strung out to the point where people are rolling back in ones and twos, despite instructions at the outset to keep things together.

Maybe it was the semi-wintery weather on that day, or maybe it really was the case that no one was feeling particularly antsy. But on this day, the pace was mellow, there was lots of conversation, and we even made a point to pay a visit to the local wallaby (yes, someone has a wallaby in Colorado). Regardless, everyone had a good time, no one got dropped, and we never got buzzed by any cars.

Did the Checkpoint play a role in that? It’s impossible to say for sure, but I’m not going to write off the possibility, either. It’s still early days of testing, and we’ll reserve a more in-depth report and final ratings until we’re able to log more significant time on our test samples, but right now, it’s hard to argue with a bike that’s just plain fun to ride.

Domane Vs Checkpoint 

Let’s take a big-picture look at some of the similarities and differences between the Domane and the Checkpoint.

Trek Domane Models

Here’s a select number of Domane variants and what they offer.

This is Trek's entry-level road bike with a respectable groupset for its price. A perfect choice for those dipping their toes into the world of road cylcing.

Trek Checkpoint Models

Here’s a select number of Checkpoint variants at different price points.

This is Trek's entry-level gravel bike. It's a solid choice for all beginners and most enthusiasts. It has reliable shifting and powerful brakes.

The Checkpoint has more mounts to hold your gear, while the Domane primarily has just a few for water bottle cages. The Checkpoint also has wider tire clearance to adjust the tire’s size to fit the terrain, while Domane has thinner, faster tires. 

The Trek Checkpoint is primarily a gravel bike with enough flexibility to be ridden like a road bike. The Domane, however, is primarily a road bike that was created to be taken off-road, as well.

We’ll go over the different components of some of the models of each, starting with the price. 

Price Points

Budget is always an important consideration when purchasing a new bike. Both the Checkpoint and the Domane are available in a variety of price points.

The prices of the Domane run from around $1000 to over $8000, depending on the model. The lower-end models will have aluminum frames, which costs less to produce. They’ll also have lower-end components, such as Shimano Claris.

High-end components, such as Shimano 105 are available at higher price points. Your bike will still shift fine, it just won’t have as many gears, and the gearing might be a little bit heavier. 

The prices of the Checkpoint, on the other hand, run from $1699 to over $12,000. The base Checkpoint model is a little more money than the base Domane because it comes standard with hydraulic disc brakes and Shimano GRX, which are better suited for gravel. 

The geometry of both the Checkpoint and the Domane is similar, but there are some differences.

Because the Domane is more geared towards road racing, the stack and reach are slightly shorter than on the Checkpoint. This geometry makes it a little more responsive, which some may interpret as twitchy. Although the Domane is marketed as a race bike, Trek also points out that the overall geometry of this bike is for endurance, so it is more comfortable for longer rides. 

On the other hand, the Checkpoint has a slightly longer frame with a higher stack and longer reach . It’s a slight difference but will make the Checkpoint feel a little bit more stable in rough conditions such as loose gravel and sharp turns. 

The interesting point on the geometry of these bikes is that the Domane has a lower bottom bracket than the Checkpoint. A lower bottom bracket means a lower center of gravity, which offers a bit of stability. Conversely, the higher clearance on the Checkpoint gives the bike a little more room for rough terrain. 

If you want a little bit more of a race bike, go for the Domane, but if you want a little more of a gravel bike, go for the Checkpoint . 

Frame Material 

Both the Domane and the Checkpoint entry-level variants are made of aluminum, and if you want to opt for a full carbon bike, you need to spend at least 3300 dollars on the Domane SL5, whereas the cheapest full-carbon Checkpoint SL6 starts at 4000 dollars.

Generally, entry-level bikes are made from aluminum to give them a lower price. Aluminum provides a snappy ride, but it can feel harsh and bumpy, too. You might wear out a little bit faster with aluminum unless your bike comes with a carbon fork and seat post, which will help absorb some of the road chatter. 

If you want a smoother, more compliant ride, you’ll want to invest a little bit more into a carbon frame. It’s lighter, more comfortable, and easier to handle, but they do cost more. 

Both types of frames are suitable for road and gravel; it just depends on your budget and your personal preference.

the Domane, like most road bikes, is geared to keep your perfect cadence, whether going uphill, downhill, or speeding across the flats . It has chainrings in the front, known as a 2x, and a cassette in the back with various cogs.  

The entry-level Domane uses Shimano Claris, which is only an eight-speed bike. This is fine if you’re a beginner, but a more seasoned roadie will want the 11 or 12-speed cassette in the higher models. The higher-end Shimano parts are also lighter, which will help you shave off a little weight on the bike, too. 

The Checkpoint, on the other hand, has more options. Some of the models come in a standard 2x drivetrain. However, a few models also come with the option of using a 1x drivetrain .

A 1x drivetrain on the Checkpoint is significant because it limits the number of gears you have and also means you need to tailor the gears even more specifically to your terrain.  So you’ll either have gears aimed towards keeping that perfect cadence on the flats, gears that will get you uphill easily, or that will give you more speed heading downhill.

Hydraulic disc brakes give you the most stopping power. The Domane offers rim brakes on their cheapest model, which is probably just fine if you are a beginner mainly riding flat roads or at least in good weather conditions.

 However, if you’re hitting gravel or steep descents, you’ll want the higher-end Domane with the hydraulic disc brakes or the Checkpoint, which comes standard. 

The best thing about these bikes is the tire clearance. Trek turned the Domane into an all-road bike by giving it wider tire clearance. So if you want to ride on the road with an occasional gravel ride, you can simply swap out your road wheels for a pair of gravels in 38. 

Beware though that the entry-level Domane has a smaller clearance because of the caliper brakes. It’s not going to be suitable for any serious gravel riding.

If your primary goal is gravel with occasional road rides, you can put up to 45c wheels on the Checkpoint, but swap them out for a pair of slicks when you meet up with your roadie friends. 

Final Thoughts

If you’re primarily an adventurer at heart, the Checkpoint is a better option as it is mainly built for exploring trails, but if you’re first and foremost a speed lover, you should probably opt for the Domane. Once you’ve decided, which one best suits your riding style, you can go up the component charts as far as your budget and needs allow you to.

Happy pedaling!

Trek Domane vs Checkpoint

If you’ve been searching high and low in the cycling space, you probably know that Trek’s bike lineup offers top-quality, drool-worthy rides. Among them, the two beasts – Trek Domane and Checkpoint, command special attention. Maybe you’re looking to buy a new bike, or perhaps you’re just keen to know more about these powerful machines. Either way, you’re at the right spot.

Trek’s gravel/endurance bike lineup: Domane and Checkpoint

So, what’s the scoop with these two models? The  Trek Domane  is not a gravel bike rather, revered as a versatile endurance road bike. It shines on all types of surfaces, but it particularly excels on rough roads – think gravel or cobbles. It’s your perfect partner for long, challenging rides where comfort and stability take precedence.

On the other hand, the  Trek Checkpoint  ALR 5 is your quintessential gravel bike. It’s built specifically for the rough and rugged. With terrific traction, smooth handling, and impressive versatility, the Checkpoint is designed to take you places where regular road bikes would hesitate.

Trek Checkpoint and Domane Comparison

Now, with such incredible features, it’s tricky to decide between the Domane and the Checkpoint. Both have their charm and strength. So, how do we choose? Well, that’s where a side-by-side comparison could help.

Comfort Vs. Control:  The Domane, with its dedicated endurance geometry, takes home the gold when comfort is considered. However, for off-road control and agility, the Checkpoint takes a slight edge, thanks to its gravel-optimized design.

Road Vs. Off-road Optimization:  While the Domane is suited to withstand a fair share of battered roads and gravel paths, it performs its best on more traditional road surfaces. The Checkpoint, being a thoroughbred gravel bike, excels on off-road trails and unpredictable terrains.

In terms of pricing, both these models carry a hefty tag – characteristic of the top-notch features and quality Trek offers. But for those of you who are on a budget, the good news is, both these models come in a variety of specs and price points.

So, should it be the Domane or the Checkpoint? At the end of the day, the decision boils down to your specific needs. If you frequently ride on both roads and gravel, and comfort is a high priority, the Domane should fit the bill. But if your bike adventures lean more toward unpredictable off-road terrain and you relish tackling rocky paths, then the Checkpoint would be your ideal gravel partner. Either way, you’re in for an exhilarating ride! 

Frame and Geometry

Two distinctive bikes that have marked their territory in the world of cycling are the Trek Domane and Checkpoint. If you’re a gravel/endurance biker, these bikes aren’t new to your ears, right? However, wondering which one to choose? Let’s dive into a quick comparison between these two popular Trek models.

First, it’s important to understand that the frame and geometry of a bike play a significant role in its riding experience. It determines your position and balance on the bike – a critical factor for long rides. So let’s talk about each bike’s frame and geometry.

Different sizes and frame materials available

The Trek Domane  is available in an assortment of sizes, accommodating riders of different heights. The frames are engineered with high-quality carbon and aluminium, thereby providing high strength and sturdiness. Meanwhile, it also caters to varying budget ranges.

On the other hand, the Trek Checkpoint  also offers multiple size variants, ensuring a perfect match for riders tall and short. Its frame is primarily composed of carbon fibre, promising longevity and durability. The Checkpoint, intended for versatile riders, fits into moderate budget categories.

Trek Domane vs. Checkpoint: Which One to Choose?

CyclistsHub is supported by its readers. We may receive a commission if you buy products using our links.

Trek’s gravel bike lineup consists of Domane and Checkpoint . Below, I will explain their differences and advise you on which one to buy.

KEY TAKEAWAY

Browse Trek Checkpoint bikes here .

Keep reading for more information on the differences between ALR, SL, and SLR and a breakdown of individual models and generations.

I’ll also recommend models that offer the best price-value ratio.

Trek Domane vs. Checkpoint

Here’s a closer look at these two bike families and their main features.

Frame & Geometry

Trek Domane and Checkpoint bikes are available in multiple sizes and frame materials . The entry-level bikes are made of aluminum , while the higher-end ones are made from carbon ( learn more ).

The Domane could be classified as an endurance road bike. It has a more relaxed geometry (compared to other road bikes), which leads to a more upright (and less aerodynamic) riding position.

Checkpoints have an average gravel geometry . But they have a higher bottom bracket for better maneuverability in terrain and more clearance than Domanes. This also allows for more aggressive cornering and handling.

Wheels and Tires

Wheels and tires are one of the main differences between Domane and Checkpoint.

Domane is closer to road bikes – it has smoother and narrower tires . It fits up to 38mm tires (without fenders), which allow you to ride dirt roads or light gravel.

Checkpoint , on the other hand, can fit up to 45mm knobby tires , which are more suitable for rougher gravel, flow trails, forest roads, etc.

Weight and Aerodynamics

Domane bikes (except those aluminum ones) are lighter on average by 1 kg than Checkpoint bikes. This is because, in road cycling , weight is more of a factor than in gravel biking .

The main weight difference comes from the frame and components (groupset and wheels). As with any bicycle, the more expensive the bike, the lower its weight.

The same applies to aerodynamics. Trek claims that Domane bikes are aerodynamic. However, the newer generations of Checkpoint bikes also appear to be aero.

Unfortunately, there is no side-by-side comparison between the two bikes. However, it’s safe to assume that Domane bikes would be slightly faster under the same conditions.

Price-wise, these bicycles vary among families. Checkpoint bikes are generally more expensive than the same series of Domane bikes.

Compared to other bicycle brands, Trek is considered one of the pricier ones. However, in exchange for that, they offer attention to detail, a worldwide distributor network, and a lifetime warranty.

The higher-end bikes from the Domane and Checkpoint family feature an IsoSpeed decoupler . It’s a technology that absorbs shock and vibrations, making the ride smoother and more comfortable.

The newer generations of these bikes also have fully integrated cable routing , improving the overall appearance of the bike.

Carbon-frame Domanes and Checkpoints also have hidden storage compartments (usually in the down tube) for extra storage space. It’s useful for storing a tire repair kit, for example.

And, of course, both bike families have additional mounting points for fenders and racks. However, Checkpoints offer more options.

Trek Gravel Bikes Range Explained

You already know the differences between Domane and Checkpoint. But what do the abbreviations and numbers in their names mean (e.g., Trek Domane SLR 7)?

The abbreviation refers to the frame material. The key is as follows:

• AL(R) are aluminum frame bikes.
• SL are bikes with 500 series OCLV*  carbon (mid-range).
• SLR are bikes with 800 series OCLV carbon (high-end).

*OCLV carbon is Trek’s patented carbon fiber process ( learn more ).

And the numbers mean the groupset:

• Models ending with 2 use Shimano Claris (R2000) groupset.
• Models ending with 3 use Shimano Sora (R3000) groupset.
• Models ending with 4 use Shimano Tiagra (R4700) groupset.
• Models ending with 5 use Shimano 105 (R7000) or Shimano GRX groupset.
• Models ending with 6 use Shimano 105 Di2 (R7100) or SRAM Rival AXS groupsets.
• Models ending with 7 use Shimano Ultegra Di2 (R8100), GRX , or SRAM Force AXS groupsets.
• Models ending with 9 use Shimano Dura-Ace Di2 (R9200) or SRAM Red AXS groupsets.

Trek Domane Bikes Compared

The following table compares all Trek Domane bikes.

Trek Checkpoint Bikes Compared

The following table compares all Trek Checkpoint bikes.

So, should you buy Trek Domane or Checkpoint?

Buy Trek Domane if you want a fast bike for paved roads with the possibility of riding in light terrain, such as dirt and forest roads or light gravel.

My recommendation is to choose models with Shimano groupsets, as they are lighter and cheaper than those with SRAM. Domane SL 6 with Shimano 105 Di2 offers the most features of the higher-end versions.

Consider Trek Checkpoint for more gravel-oriented riding and racing, having fun off-road, and being able to tackle more demanding terrains.

The ALR models are a great entry-level choice. I believe the SL 6 provides the best price-value ratio. It offers electronic shifting, is reasonably lightweight, and doesn’t cost a fortune. SLR models are too expensive unless you want the best frame Trek offers.

Trek Gravel Bikes FAQ

Trek gravel bike frames are made in Asia (mainly in Taiwan and China). Then they are shipped to Wisconsin, where they are painted and assembled. However, the design and R&D center is still in Wisconsin, US. ( Source )

Project One is Trek’s program for customizing bikes. You can choose specific color options and some components to match your liking and preference.

Some models have women-specific options. However, in recent years, Trek has addressed women’s sizing by listing more bike sizes (e.g., size 44), with the smaller sizes being more suitable for women.

Trek offers a lifetime frame warranty. However, it’s only valid for the first owner. The second (and subsequent) owners have a shorter, 3-year warranty. You can read the Trek warranty page for more info.

IsoSpeed is Trek’s technology for absorbing vibrations from the frame and seatpost that would otherwise be transferred to your body. Learn more about IsoSpeed .
