Should I Buy This Bike?

Trek redesigned their popular range of mid-travel Fuel EX trail bikes for 2020 with major changes to the geometry and the ABP rear suspension design. The new Fuel EX models, including the EX 8 we tested, are in line with modern trail bike geometry trends, plus they've been given a bump in front suspension travel with 140mm travel forks paired with 130mm of rear-wheel travel. The ABP (Active Braking Pivot) suspension design provides a supportive pedaling platform, great small bump sensitivity, composed big hit performance, and is unaffected by braking forces. Trek makes bikes for the masses, and despite lengthening and slackening the Fuel EX the geometry remains relatively middle of the road by today's standards, though this isn't necessarily a bad thing. This bike has an easy-going demeanor with predictable handling that is comfortable and fun to ride at a range of speeds and nearly any type of terrain, yet is still capable of charging relatively hard. The EX 8 is the most expensive aluminum-framed model in their line, but we feel it is reasonably priced with a shred-ready component specification that includes quality suspension, a GX Eagle drivetrain, a 150mm dropper, and meaty 2.6" wide tires. We didn't feel there was a lot of wow-factor, but we also found it hard to complain about the versatile and well-rounded performance of this reasonably priced mid-travel ride.

Interested in a bike that charges a little harder on the descents? The Norco Optic has similar travel numbers with 125mm of rear suspension paired with a 140mm fork. The Optic's aggressive geometry gives it a serious appetite for the descents, and it slays downhill like a bike with more travel. Its long wheelbase and slack head tube angle make it notably stable at speed and confident in steep, rough terrain. It feels similar to the Fuel EX on the climbs and in rolling terrain but blows it away on the descents. Carbon Optic builds range from $3,749 to $8,999.

Do you like smaller wheels and playful ride? The Santa Cruz 5010 rolls on fun-sized, 27.5-inch wheels and has 130mm of rear wheel travel and 140mm fork. It's got modern, but not extreme, geometry that makes it a versatile trail weapon that performs well on both the climbs and descents. A lively and playful demeanor is the hallmark of the 5010, and this bike likes to be flicked, slashed, and aired off every obstacle in the trail. The VPP suspension platform provides great pedaling support, efficiency, and a bit of pop. While the Fuel EX is impressively versatile and user-friendly, the 5010 will appeal to the rider who wants to turn the mountain into their playground. The 5010 comes in carbon frames only with complete builds ranging from $4,099 to $6,899.

Frame Design

The 2020 Fuel EX 8 is built around Trek's Alpha Platinum Aluminum frame with 130mm of rear-wheel travel. Trek has used their Active Braking Pivot (ABP) rear suspension design for some time and that continues with the redesigned Fuel EX models. Unlike previous ABP designs, the new Fuel has a fixed lower shock mount as opposed to the floating shock mount of the past. ABP is basically a four-bar design where the main pivot is attached to the seat tube just above the bottom bracket, the shock attaches to a magnesium rocker link about halfway up the seat tube, and there is a pivot point around the rear axle. This rear axle pivot is intended to allow the suspension to move freely regardless of braking forces, hence the name Active Braking Pivot . Trek has included their Mino Link flip chip at the junction of the seat stays and the rocker link which adjusts the head and seat tube angles by 0.5-degrees and changes the bottom bracket height by 7mm. The frame has internal Control Freak cable routing, a knock block headset, a downtube guard, and chainstay protection. It comes in sizes XS-XXL with XS and Small frames getting 27.5-inch wheels and Medium to XXL frames coming with 29-inch hoops.

We found the frame sizing of the Fuel EX 8 to feel a little small, so our 6-foot tall testers rode a size XL for this test. We measured our test bike and found that it had a 654mm effective top tube and a 490mm reach. In the Low setting the head tube angle was 65.75-degrees and the effective seat tube angle was 75.25-degrees. The bottom bracket was 342mm off the ground with 438mm long chainstays and a 1240mm wheelbase. Both the reach and wheelbase measurements sound quite long, but this bike feels smaller than those numbers suggest. It tipped the scales at 31 lbs and 7 oz set up tubeless without pedals.

Downhill Performance

The Fuel EX 8 is a rock-solid downhill performer. It didn't blow our testers away on the descents, but it never let them down either. This bike was comfortable and fun to ride on a huge range of terrain and is capable of tackling all but the gnarliest of steep and rough trails. The geometry strikes a nice middle ground that gives it its impressive versatility, and the new ABP suspension design delivers stunning sensitivity and small bump compliance and a deep feeling stroke that handles big hits with composure. For the price, the components on our test bike are solid and perform well on the descents.

trek fuel ex 8 trail mountain bike review - the updated geometry is the real story with the new fuel models. the...

The geometry of the Fuel EX 8 is a dramatic improvement over the previous version, and Trek has addressed most of the current trail bike trends. A longer reach and wheelbase, slacker head tube, steeper seat tube, and flip-chip adjustable geometry are a proven recipe for enhanced downhill performance and capability. Interestingly, our testers found the frame sizing to feel small. Our six-foot tall tester felt cramped on the Large frame while our 5'-10" tester felt just about right. If you're on the cusp of a frame size, we'd suggest taking a test ride and possibly sizing up. Once on the right size frame, testers felt the reach was adequate and the wheelbase was just about right for a modern mid-travel trail bike. It's long enough to feel stable and planted at high speeds, but not so long that it becomes unwieldy at low speeds or in tight terrain. The 65.75-degree head angle, in the low setting, is slack enough to tackle the majority of trails with confidence without being so slack that steering becomes sluggish or the bike feels awkward at low speeds. The geometry is also adjustable using the Mino-Link flip-chip. There is a 0.5-degree difference in the head and seat tube angles and the bottom bracket changes by 7mm between the High and Low settings. We spent the majority of our time testing the Fuel EX 8 in the Low setting which we found to be excellent for everyday trail riding. The High setting's steeper head angle provided marginally crisper handling and we feel it would be good for riders whose trails are smoother and moderate in difficulty.

trek fuel ex 8 trail mountain bike review - the ex 8 isn't the hardest charging bike we've tested recently but...

The ABP suspension design works well. Trek has moved away from the full-floater design on the previous Fuel models to a fixed lower shock mount. The Fuel EX 8 we tested comes with a Fox Float Performance rear shock with custom-tuned RE:aktiv damper technology. There's a lot of technical jargon associated with the RE:aktiv shocks, but the gist of it all is that it has regressive damping intended to give it a supportive pedal platform while remaining highly sensitive with excellent small bump compliance. Testers found it to soak up big hits with ease with a relatively bottomless feel, especially for a 130mm bike, with a supportive mid-stroke that you could push off of out of corners and get some pop when you're looking for it. It wasn't the most playful or lively bike we've ridden recently, but it wasn't glued to the ground either. The knock block headset is a necessity on this bike to prevent the fork from damaging the downtube, but our testers noted that it does limit your turning radius is super tight switchbacks.

For the price, we were quite pleased with the component specification of the Fuel EX 8 , and it works well on the descents. The Fox Rhythm 34 fork is nothing fancy but felt sturdy, impressively supple, and balanced with the rear suspension. The Shimano Deore brakes work well enough, with a very on/off feel that Shimano brakes are known for. The Bontrager Line Comp 30 wheels felt stiff and sturdy, and the 2.6" Bontrager XR4 tires worked surprisingly well in a huge range of conditions and were more durable than expected. We can't complain about the Bontrager Line dropper post, the 150mm was adequate and the 1x style remote lever felt good. The cockpit was well appointed with a properly wide 780mm handlebar and a short 50mm stem with a sturdy 35mm clamp.

Climbing Performance

We were pleasantly surprised by the climbing performance of the Fuel EX 8 . We've read reviews that complain of this bike relying heavily on the compression damping switch of the rear shock, but we found it to be quite supportive with minimal pedal induced bobbing. Sure, it's a little heavy at over 31 lbs, but this bike felt efficient and responsive and capable of taking on any length of climb or ride. The geometry is comfortable and the component grouping won't hold you back.

Assuming you're on the right size frame, the geometry of the Fuel EX 8 is comfortable on the climbs. Once again, on the Large frame, our six-foot tall testers felt cramped in the cockpit, after sizing up to an XL they felt far more comfortable. We measured the reach on the XL frame at 490mm, but it certainly didn't feel that long or stretched out. The 1240mm wheelbase also sounds lengthy, but again, it didn't feel that long and this bike was plenty maneuverable on the climbs. One limiting factor to this bike's maneuverability is the knock block, which we found came into play occasionally in super tight switchbacks and technical terrain. The 75.25-degree effective seat tube angle is a little bit slacker than you'll find on most bikes in 2020 but it still places you almost directly above the bottom bracket for pushing straight down on the pedals.

The RE:aktiv shock valving works very well with the ABP suspension design to create a supportive pedal platform on the Fuel EX 8 . It seems to us that there is something to the regressive damping technology, and we climbed with the shock in the open position the majority of the time. In the open position, there was very minimal pedal bob when seated and a relatively standard amount when out of the saddle. Despite the firm climbing feel of the rear suspension, it still felt sensitive and soaked up small bumps and helped to enhance traction. Flipping the compression damping switch to the middle position provided an even firmer pedal platform, though testers felt that was best saved for long fire road or paved climbs.

trek fuel ex 8 trail mountain bike review - the abp suspension with the re:aktiv shock works well to provide a...

Overall, the component grouping was generally fantastic on the climbs. The SRAM GX Eagle drivetrain is reliable with plenty of gear range and crisp shifting. The Bontrager XR4 rear tire in the 2.6" width has a huge contact patch and provided ample climbing traction on virtually all surfaces. Testers did find, however, that the Bontrager Arvada saddle wasn't the most comfortable and would likely be the first thing we'd upgrade. The overall weight of the Fuel EX 8 is also notable at 31 lbs and 7 oz. This bike is a bit on the heavy side, though we have to admit the weight went largely unnoticed while riding.

The Rhythm 34 fork is nothing to write home about, but the recent...

At a retail price of $3,450, the Fuel EX 8 qualifies as being reasonably priced these days. We feel that this represents an above-average value for a well spec'd trail bike from a major brand like Trek. This bike comes ready to rip and there's seriously nothing that needs to be upgraded to get out and get after it. If this is out of your price range, there are two less expensive models to choose from, and for those looking to go a bit higher end, there are 6 different carbon builds.

trek fuel ex 8 trail mountain bike review - the fuel ex 8 is a solid trail bike offered at a reasonable price...

Trek did a good job when they redesigned the Fuel EX , creating a more versatile and well-rounded mid-travel trail ripper. This bike has a very approachable and easy-going demeanor, with just enough travel and the angles to be a blast to ride in all but the most aggressive of terrain. There's nothing particularly exciting about it, but there's little we didn't like about it either. We feel this is a solid all-around trail bike and a reasonably priced and sensible option for a lot of riders and locations.

Other Versions

Trek makes nine different versions fo the new Fuel EX including the EX 8 model we tested which is the top of the line aluminum framed option. They no longer offer women's specific models, though they do make the bikes in 6 different sizes to fit a huge range of rider's body shapes and sizes.

They make 3 aluminum-framed models, all of which share the same Alpha Platinum Aluminum frame and geometry, starting with the budget-friendly Fuel EX 5 which retails for $2,100. The EX 5 comes with a RockShox Recon RL fork and a Deluxe Select+ rear shock, a Shimano Deore 10-speed drivetrain, wide tubeless-ready wheels and 2.6" tires, and a TranzX dropper seatpost.

The mid-range aluminum model is the Fuel EX 7 at $2,900. It comes with a RockShox Gold 35 fork, a Fox Float Performance DPS EVOL rear shock, a SRAM NX Eagle drivetrain, and a Bontrager Line Comp 30 wheelset.

Trek Fuel EX 8 Gen 6 review

Does Trek's sixth-generation trail flagship live up to the hype?

Great frame, with perfect handling and suspension feel; adjustable geometry and sizing options mean a bike fit for all; happy on any level of trail

Cockpit harshness; mediocre tyres; poor brakes; expensive

The Trek Fuel EX 8 Gen 6 is part of the sixth generation of the US brand’s flagship trail-bike family, launched in 2022. It went live hot on the heels of the aesthetically similar, but motor-assisted Fuel EXe bike.

The Fuel EX family offers 140mm of rear-wheel trave l, paired with 150mm forks, and is targeted at more aggressive trail bike riders. The bulk of the bikes are offered with 29in wheels , the XS frames have 27.5in wheels, while those looking at size-small bikes get the pick of both sizes.

One of the most adjustable bikes on the market, the Fuel EX offers two geometry adjustments, as well as suspension adaptability and mullet compatibility. With an expansive range, covering alloy and carbon models, there are bikes for many pockets.

This EX Gen 6 sits at the top end of the alloy range, and while the spec list isn’t dripping in top-end kit, the selection of parts suggests solid performance should be expected.

Trek Fuel EX 8 Gen 6 frame and suspension

Trek Fuel EX 8 Gen 6 full suspension mountain bike

The frame uses Trek's Alpha Platinum aluminium, which is butted and hydroformed into the tube shapes the brand desires.

The down tube features a storage port, into which tools, snacks or pumps can be stashed, situated under the bottle cage.

Under the tube is a two-piece rubberised bolt-on protection strip to keep the frame safe. It extends the length of the down tube, which is great to see.

Threaded bottom bracket shells will appeal to home mechanics, while there are ISCG05 mounts around the shell too.

Thick rubberised protection keeps the rear triangle running quietly and the paint chip-free.

A wide 34.9mm seat tube means large-diameter droppers are fitted - a boon when it comes to durability.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Trek uses its ABP (Active Braking Pivot) suspension linkage on the Fuel EX. This places the rear pivot concentric to the rear axle (rather than on the chainstay or seatstay, as on most suspension systems ).

This, Trek says, separates braking forces from the suspension’s action. The idea is that suspension remains active while braking.

Normally, the torque applied to the seatstay by the brake during braking interferes with the suspension, hampering the wheel’s ability to track the ground while slowing down.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Trek says the seatstay, which floats between the rear pivot and the rocker link, separates the two competing forces.

The suspension linkage features a two-position lower shock mount on the frame (the ‘Progression Chip’), enabling you to run a more progressive leverage curve, offering improved bottom-out protection, or the ability to run a coil shock , which is more linear than a standard air shock.

This feature should appeal to more aggressive riders.

Trek Fuel EX 8 Gen 6 geometry

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Trek has given the Fuel EX plenty of adjustability in terms of the bike’s geometry.

The MinoLink has been seen on numerous Trek bikes. This flip chip in the suspension rocker gives Low and High settings, altering head and seat angles by 0.5 degrees. It also alters the BB height by 8mm.

There are also three headset options – Slack, Neutral and Steep. In Slack (and MinoLink in Low), this offers adjustment from 63.5 degrees to 64.5 degrees (Neutral) up to 65.5 degrees in Steep. There's minimal impact on other areas of the bike's geometry.

Bikes ship with the Neutral headset (and the bike is tested here in Neutral), with a rotatable headset cup available aftermarket, offering the Slack and Steep options.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Finally, in terms of adjustability, if you stick the bike in the Steep setting with a 160mm fork, the Fuel EX can be run as a mullet bike , with a 27.5in wheel in the back.

Overall, the geometry is very modern. Reach figures are long, the head angles are slack and the seat tube angles are steep, at around 78 degrees.

Chainstay lengths alter with size, too, ranging from 435mm to 450mm across the (impressive) eight sizes on offer. These go from XS to S (27.5 or 29in), Medium and Medium Large, Large, XL and XXL.

Trek Fuel EX 8 Gen 6 specifications

Trek Fuel EX 8 Gen 6 full suspension mountain bike

At £4,350, it’s fair to say the EX 8 doesn’t offer the best value around. However, many of the spec choices are solid, and the alloy chassis is great.

Suspension comes from Fox , in the shape of a Rhythm-level 36 fork with 150mm travel. This comes with the basic GRIP damper, which has a lockout dial on the top of the fork and low-speed rebound adjustment at the bottom.

At the rear, there’s a Float X shock, in its Performance flavour. This has a piggy-back design, giving it a higher oil volume, which in turn improves performance consistency on long descents.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

The Performance level largely means there’s less adjustment than its pricier siblings, but you still get a lockout lever.

The drivetrain is a mix of Shimano XT, SLX and Deore, as well as an e*thirteen 9-50t cassette. The brakes on my test bike are the new mineral-oil based DB8 brakes from SRAM, with 200/180mm rotors. Some bikes may come with M6100-level Shimano brakes, though.

Bontrager (Trek’s in-house parts brand), provides the bulk of the finishing kit, from the cockpit to the saddle, as well as its Line 30 Comp wheels, and mid-aggressiveness XR5 Team Issue 29x2.5in tyres.

Trek Fuel EX 8 Gen 6 ride impressions

Trek Fuel EX 8 Gen 6 full suspension mountain bike

This bike was tested as part of our 2023 Bike of the Year test. It was compared to seven of the best trail bikes , listed later.

I took all the bikes to the same locations and trails for some dedicated back-to-back testing on a wide variety of terrain.

From hand-dug tracks in the woods to trail-centre laps and BikePark Wales’ rocky runs, I ensured the trail bikes were exposed to every type of trail such a bike is likely to be ridden on.

Riding the bikes back to back, usually with four in each testing session, ensured I was able to pick out the finer performance points of each one.

Trek Fuel EX 8 Gen 6 climbing performance

Trek Fuel EX 8 Gen 6 full suspension mountain bike

The Fuel EX does a solid job when the trails start to ascend.

The seated position is excellent, with a steep seat angle putting you right where you need to be over the cranks when the front wheel is higher than the rear.

When your weight shifts rearward, the suspension doesn’t seem to squat much, either, so the seat angle rarely dips from its steep position too much.

Seated, the suspension is as good as solid when pedalling, with minimal movement of the shock under regular pedalling loads, leading to an efficient feel. The SE5 tyres roll fairly fast, thanks to their low tread height.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Stand up, and you can get the suspension bobbing about, but it doesn’t feel as wallowy as many in this situation, and the lockout lever is within easy reach on smoother drags.

Get to a step up in the trail and the suspension stays static as the rear wheel crests the ledge. Traction on slippery roots from the SE5 rubber could be better too – though the trade-off would likely be some rolling resistance.

When stood, you get the first impression that the chassis is stiff – there’s no spaghetti feeling as you put power through the cranks, and the whole setup feels, simply put, solid.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Despite all this, it’s not the fastest climbing bike ever. It has a reassuringly composed feel, rather than light and flighty, and during testing I never really felt myself being egged on to ramp up the watts to get up the hill faster. It’s a bit of a sit and spin bike.

The Shimano drivetrain is good, with Trek speccing a largely XT groupset. Cassette specs seem to vary, like the brakes, with e*thirteen (as I have) and Shimano SLX being listed.

The e*thirteen’s shifting performance isn’t quite as slick as a Shimano alternative in my experience, but does feel a little quieter when the drivetrain is covered in grit and grime, compared to Deore/SLX cassettes.

Trek Fuel EX 8 Gen 6 descending performance

Trek Fuel EX 8 Gen 6 full suspension mountain bike

The solidity that was evident on the climbs is almost more so on descents. Trek has made a super-stout chassis that gives the Fuel EX an impressively composed feel on the trail.

It is almost unshakeable, pretty much regardless of the terrain.

The suspension doesn’t have a light, flighty feel, but is nicely damped, offering buckets of traction, whether you’re on the brakes or not, and provides ample isolation from the minutiae detail of the trail, without leaving you feeling entirely disconnected from it. Lighter riders may well find the shock over-damped.

On big hits, after a slightly harsh entry into its travel, the shock is controlled, with a smooth transition towards the bottom of its travel, avoiding any nasty clunks as the shock bottoms out. This is in the normal rather than more progressive shock setting too.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

In this, I struggled to get through all the travel, suggesting it may well work better with a coil shock (which is, by its very nature, less progressive at the end of its stroke).

Drop the bike into a corner, and the chassis doesn’t flex, pushing your weight straight onto the tyre’s shoulder in a reassuring manner, and communicating exactly what’s happening through the rubber. It carves corners beautifully.

Fire it through some janky rocks, and the bike seems to shrug off any attempt to push it off-line and you into trouble. It doesn’t display full monster-truck tendencies, but it’s certainly a bike that feels happy being pointed somewhere in the distance and then allowed to get there in as straight a line as possible.

It’s a similar story on rolling trails, too. The suspension enables you to push and pump the bike through undulations, gathering speed, avoiding feeling like you’re trying to compress a marshmallow. Turn the pedals and you’re projected forward with ever-increasing speed.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

It even displays ample levels of agility, too – want to add a few air miles to your account? There’s support there to boost off a lip. Keen to whip the rear wheel round a tight bend? It’ll drop its shoulder and scrabble its rubber round when required.

With a 485mm reach (large) and 64.5-degree head angle, the Fuel EX should excel on steep tracks, especially because the Fox Rhythm 36 has a similarly stout chassis and ample support when needed.

However, you do need to trust both the brakes and the tyres in this situation.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

The new SRAM DB8 brakes didn’t impress me in testing. They feel wooden through the lever, with a disconnected lever feel, and their power levels are down on both the SRAM G2 and Shimano’s similar offerings.

Given Trek lists both the DB8 and Shimano M6100-series brakes on its spec list, given the choice, I’d opt for the Shimano stoppers.

While I’ve been relatively complimentary of the tyres so far, their performance is outshone by Maxxis tyres on other trail Bike of the Year bikes.

The tread depth is low, and so in sloppier conditions they don’t have the same bite. The slightly more rounded profile means the shoulder tread doesn’t engage the dirt as effectively as other tyres might.

Trek Fuel EX 8 Gen 6 full suspension mountain bike

Compared to Maxxis’ 3C MaxxTerra rubber and EXO casing , these tyres can’t compete. They ping over rocks more and have less traction on damp rocks and roots.

Early testing on the loam, mud and roots of the forest left me impressed. But later trips to the high-frequency rocky chatter of BikePark Wales revealed the Trek’s other weaknesses – the stiff frame, Line 30 wheels and oversized bars.

These combined to transmit a whole lot of buzz straight to my hands. Add in under-powered brakes, and arm fatigue was an issue on prolonged rocky descents.

How does the Trek Fuel EX 8 Gen 6 compare to the Merida One-Forty 700?

Pack shot of the Merida One-Forty 700 full suspension mountain bike

Trek and Merida each launched great new trail bikes in 2022. Both have clearly concentrated on the quality of their chassis, and target the trail rider who doesn’t want descending performance to be compromised.

The Trek has a very assured feel – it’s calm, composed and really easy to ride. It’s agile and communicative too.

The Merida (in the Long size that I tested) is radical in its shape, and climbs exceptionally well. It has a touch more pedal feedback, but both will tackle steep tech with ease.

Merida pips the Trek, though, thanks to its better tyres and cracking value for money. It’s over £1,000 cheaper, and other than the single-can shock, rather than piggyback, I can’t see where it loses out spec-wise.

Trek Fuel EX 8 Gen 6 bottom line

Trek Fuel EX 8 Gen 6 full suspension mountain bike

The Fuel EX is undoubtedly a great trail bike, and very nearly made it into my top three for this Bike of the Year category.

It was the rockiest tracks that separated the best from the rest, though, and the stiff front end, as well as questionable value, squeezed the Trek off the podium.

It’s a bike that best rewards an aggressive, rather than passive, riding style.

Treat it right (and maybe get lucky with the brake specs) and you won’t be disappointed by the Fuel EX.

Trek Fuel EX 8 review – still one of the best trail MTBs?

Trek’s alloy fuel ex trail mountain bike lacks the latest features but is the overall package still a winner.

Trek Fuel EX 8

BikePerfect Verdict

Heavy frame that misses the latest features but still a great package for fast and precise all round mountain biking

Tight, precise frame

Sorted all round handling

Very efficient suspension feel

Durable Shimano kit

Excellent sizing options

Heavy frame

No internal storage

Press fit bottom bracket

Top Fuel is more playful

Why trust BikePerfect Our cycling experts have decades of testing experience. We'll always share our unbiased opinions on bikes and gear. Find out more about how we test.

Trek’s Fuel EX has been one of the best mountain bikes in the world for years, but the alloy-framed 8 is lacking some of the features the latest alloy and carbon Treks. High-durability component spec matches the vibe of a really well-balanced bike. One that plans ahead, hands its homework in early (having double checked it) and rarely puts a wheel wrong or goads you into being silly yourself. So how has Trek done that and is there a better option in the range if you want something short on travel but big on fun?

Trek Fuel suspension

Design and aesthetics

Trek has been using a rocker link-driven, vertical shock suspension design on its bikes for so long that “Looks like a Trek Session” is a cliche on most MTB forums. No surprise then that the Fuel EX continues the clean looks which leave plenty of room for a big bottle on the down tube and strap-on storage. You don’t get the internal storage of the newer Top Fuel alloy frame though and this older frame still uses a press-fit bottom bracket rather than reverting to a more reliable threaded  format. There are ISCG chain keeper tabs on the BB though, a wider-angle Knock Block steering limiter to stop bars hitting the frame in a crash and rear axle concentric ABP rear suspension pivot. Cunning zip tie tabbed ‘Control Freak’ internal cable routing and rubber frame armor including molded chainstay sleeves keep things quiet. 

You also get the 0.5-degree geometry change ‘Mino Link’ flip chip at the seat stay/rocker pivot. That changes head angle from 65.5- to 65-degrees and effective seat angle from 75.5- to 75-degrees on the Large I tested. Reach also shifts from 475 to 470mm and BB height drops from 346 to 340mm. The big win with choosing a Trek though is the sheer range of sizes from XXS to XXL including a sweet spot ML in the centre. Smaller bikes also run 27.5in wheels for proportional balance, too, although the chainstays are the same length on all frame sizes. The Fuel EX 8 is also available in three different two-tone color options.

Shimano XT drivetrain on Trek Fuel EX 8

Specification

Trek acknowledges that the ‘priority is on the parts’ with the EX 8 and the highlight is an almost complete Shimano XT drivetrain (the chain is SLX). The Fox Float shock is a custom unit, too, using a Penske race car derived RE:aktiv damper setup for a pert-pedaling feel on top of the 130mm travel. The 140mm Fox 34 fork is the stock Rhythm spec though and the Shimano brakes are basic four-piston MT400s. Bontrager’s functional Line component range completes the bike in well-judged, size-specific cockpit options although dropper post strokes are short on the larger sizes. Big volume versions of Bontrager’s XR5 and XR4 tires on Bontrager Line Comp 30mm internal rims put plenty of air between bike and trail for protection, too.

Trek Fuel EX 8 3/4

Performance

While the EX8 isn’t light at just under 15kg (a full kilo heavier than Trek claims) it’s in the ballpark for a mid-travel, alloy-framed bike at this price. What really stands out is how well it hides that weight when it comes to pedaling. The big tires don’t drag nearly as much as they look like they might, while the RE:aktiv shock and overall kinematic give it a really clean, crisp and stable platform to put down power from. That means even with three potential low-compression settings to play with, we rarely felt compelled to flick it out of full open unless we were hoofing uphill out of the saddle. Add the clean shifting, top-quality Shimano XT drivetrain and the Fuel EX is a great choice for high-mileage rides and riders. The fast-engaging ‘Rapid Drive’ freehub and relatively high ground clearance are a bonus for anyone who likes to kick hard out of corners or attack rough technical climbs, too. The efficient suspension feel still gives enough sensitivity to track the ground under power and you can drop pressures in the big tires if you’re into a proper ‘crawler/swamper’ feel. 

The 140mm fork/130mm rear travel feels well balanced on the trail and the Grip damper Fox Rhythm repeatedly proved why its our favorite cost-effective fork. Trek’s suspension calculator is accurate enough to get most people sorted on set-up for most situations. The angles and proportions of the model we tested were confident at speed on jumps but still turned in promptly on woodland twisters. Even the basic Shimano brakes feel better than normal through the neutral suspension responses created by the ABP pivot and the 200mm rotor up front boosts power, too.

While you could speed up reactions with a shorter stem, the stock setup probably suits its overall character better. That’s because while it will pop and play off trailside opportunities if you’re in the mood, it does tend to sit on top of an already relatively high ride height rather than sucking down onto the trail and railing. Interestingly that’s a big - and counter intuitive - difference to the Top Fuel 8. With slightly steeper angles, less travel, significantly different suspension kinematic and top-spec RockShox rear shock, Trek’s pocket rocket has an addictively playful charisma that’s very much at odds with it’s ‘XC’ categorization. 

In fact, despite it being heavier we’d probably opt for the Fuel EX for long marathon-style or efficiency-based events, especially as it’s significantly cheaper than its little brother, leaving you more cash for race entries and energy products. Just make sure you keep an eye on the press-fit bottom bracket and get it replaced as soon as it shows any signs of wobble/creak as that can eventually creates frame issues.

Trek’s Fuel range might be a bit backwards when it comes to assigning categories based on travel but the main thing is that the Fuel EX is still a really efficient, enjoyable and fitness/skill flattering all rounder. While it misses out on the internal storage, threaded BB and super-plush playfulness of the Top Fuel, Shimano XT will always bring a lot of hard riding boys (and girls) to the yard. Those are exactly the riders who’ll appreciate just how well this extremely well balanced bike covers ground and keeps a fresh and sharp feel long into the day, and down tough technical sections, too.

Where To Buy

Trek Logo

"A world-class trail bike"

"Fuel EX is a beautifully balanced and capable trail bike. The rear suspension is beautiful; as close to ideal as any bike I've ridden. It's sensitive where you want it to be, firm and crisp where it should be. It feels deep and controls big hits very well, and there's a nice platform for pedaling, and to pump and pop off when you're playing."

"Good at pleasing everybody"

"Fuel EX has a few tricks that help it keep a level head when outside of its comfort zone, and to be a cloud on rails when it's in the zone. Everything about the Fuel EX, which was already good at pleasing everybody, is now even better at it."

"An absolute trail rocket"

"Thanks to its burlier components, increased travel, and more aggressive geometry, it has become more of a shredder than ever! More performance, fun, and trail prowess."

Holding the cards to perfect trail days Shuffling things up and dealing a royal flush of adjustability, capable handling, and a grin-inducing playful ride, Fuel EX is back and more ready than ever to tame any trail. It packs in longer-travel suspension to broaden the horizons of a trail bike into bigger terrain and faster speeds, with a lively character that begs to be let loose on the singletrack. From lacing lines through tight aspens, to rallying root lattices and barreling through berms, any trail, any way, Fuel EX is up to get down.

  • Meet Fuel EX Gen 6

Our favorite Trek

Fuel EX proved itself a happy climber and descender. From slabs to roots and square-edge hits, the Fuel EX handled it masterfully. A damn fine trail bike right out of the box, no matter your riding style. – Vital MTB

Fuel EX is a masterpiece

Fuel EX absolutely devours chunky terrain while still retaining the ability to tractor up steep climbs. I have become convinced that a bike with long, stable geometry and mid-level travel really can provide the best of both worlds. – Freehub Magazine

Loves to ride fast, both up and down

Fuel EX is a highly adaptable bike that feels comfortable in a really wide variety of terrain, but doesn’t confuse itself for anything more or less. Bike riders, rejoice. – The Loam Wolf

Ready for anything

Fuel EX’s geometry feels ready for just about anything. There’s plenty of traction for climbing and a nice fluttery feel on descents, calmly smoothing out the trail chatter. – Pinkbike

That “juuust right” feel

Mino Link lets you quickly and easily tweak your geometry, so your bike is always tuned perfectly for the terrain and your riding style.

trek ex 8 full suspension

Slack or steep, the choice is yours

Install angle adjust headset cups (sold separately) to tweak the 64.5-degree headtube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height.

Business in the front, party in the back

Craving the nimble ride of 27.5˝ wheels but don’t want to sacrifice the speed of a 29er? No need to choose. Fuel EX is mullet-ready, just throw Mino Link in high, toss on a 160mm fork, and get ready to party.

Adjustable Leverage Rate

Easily adjust suspension progression with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails loaded with square-edge bumps. Flip it to More progressive when you’re riding fast, hitting big features, and don’t want to bottom out — or if you want to roll with a coil shock.

Sized for every rider Whether your head is above the clouds, or you stand at a lower altitude, Fuel EX’s huge size range provides an awesome fit for every rider. If you fall between XS and XXL you’ll be ready to saddle up with size-appropriate wheels and chainstay lengths for a ride that’s fine tuned to you no matter your height.

The slack and stable 64.5-degree head tube angle complements the longer-travel suspension for more confidence.

A steeper, 77.2-degree seatube keeps you perched for pedaling efficiency on long fire roads and quick, punchy climbs.

Longer reach compensates for the steeper seat tube, so you stay comfortable in the cockpit and ready for what’s around the corner.

Size-specfic chainstays give smaller riders more nimble handling, while taller riders get better front wheel traction on climbs.

New frame, new possibilities

Fuel EX’s new generation opens up possibilities for riders who want full customization. Broader shock compatibility allows for more aftermarket upgrades, like coil shocks. A larger 34.9mm seat tube accommodates larger, more robust dropper posts.

Non-stop suspension

Trek’s exclusive Active Braking Pivot keeps your suspension active while you’re braking (which is often when you need it most).

Clean and easy

Internal routing tunnels eliminate cable rattle and simplify maintenance along with a robust threaded BB. Bolt-on downtube and chainstay guards protect against rock strikes and shuttle damage while muting noise from the trail.

Stow it, don’t show it

Stash your ride essentials with in-tube storage on all models — both carbon and alloy. Included Bontrager BITS bag keeps all your odds and ends organized.

Looking for something a little different?

Sometimes less is more. Top Fuel is a shorter-travel full-suspension down-country bike ready for all-day pedal fests. It’s just as happy hammering out miles on smooth-rolling cross country singletrack as it is dipping over the backside of the mountain to explore off-the-beaten-path adventures.

Want to go bigger? Slash is a long-travel trail bike that looks like a monster truck and rides like a magic carpet. It’s built for big all-mountain terrain, racing the clock on rugged enduro lines, and having a rip-roaring good time in the rough.
