‍ This Trek Marlin 5 2022 review gives you all the details you need to decide if this budget hardtail is the right bike for you.

The Trek Marlin 5 is a solid bike for the price, but just a bit more money could get you a lot more bike. If you’re looking for a daily rider that’s comfortable on your local tails, the Marlin 5 will serve you well with a solid aluminum frame and reliable components.

I got my first mountain bike when I was twelve, and I’ve ridden everything from ultra-budget hardtails to high-performance racing rigs. For this review I dug deep into the spec’s and performance of the Trek Marlin 5 to see how this budget mountain bike measures up to the competition.

TABLE OF CONTENTS

‍ ‍ ‍ Trek Marlin 5 Performance

The Trek Marlin 5 is definitely an entry level mountain bike, so you shouldn’t expect serious capability for really technical trail riding. It does give you decent performance on easier flowy trails and definitely is enough bike to get you started in the sport.

The aluminum frame is durable and relatively light, so this bike feels rugged enough for taking on off-road riding and singletrack. It has enough capability for beginner riders, but you’ll quickly feel held back as your skills progress.

The Trek Marlin 5 definitely doesn’t have the same descending capability as a real trail bike, but it’s sturdy enough to handle some flowy singletrack.

The 100mm of front suspension isn’t very much, and you’ll find it bottoming out if you ride on very rocky, rough trails. The geometry is also limiting with a very steep head tube angle and short reach that will leave you in a sketchy position on steep descents.

The steep seat tube angle puts you in a good position for climbing efficiently. At under 31 lbs, this bike is relatively lightweight for it’s price and doesn’t feel like it’s slowing you down on the uphills.

If you’re looking at a bike like this, it’s likely it will be your only bike and will be used for multiple purposes. From trails to bike paths to cruising around town, the Trek Marlin 5 offers great versatility. I’ve used mountain bikes for commuting for years, and I think the Marlin 5 would be a great option for a commuter.

This bike is perfectly functional for commuting and comes with features like a kickstand mount and rear rack mounts so you can fully equip it for getting around town.

Trek Marlin 5 Gen 2 Frame and Geometry

The Trek Marlin 5 is built around Trek’s Alpha Silver Aluminum frame which is durable and relatively lightweight. It’s awesome that this budget frame has internal cable routing that keep your shifting and brake lines protected and hidden away inside the frame. Combined with a chainstay disc brake mount, this makes the bike look sleek and clean.

The geometry is on-par with what you’d expect for a basic hardtail mountain bike, so you won’t get the most aggressive positioning. This geometry puts you in a nice comfortable position that’s great for all-around riding. Just don’t expect to feel comfortable on super steep trails.

Specs and Components

For the $740 price, the Marlin 5 gets you a decent selection of features including hydraulic disc brakes, a coil-sprung suspension fork, and reliable Shimano shifting. The components are nothing fancy, but they perform to my expectations for a budget bike.

The Marlin 5 comes equipped with a 2x8 Shimano Altus drivetrain for 16 total gears to choose from. This setup is a bit old-fashioned as most modern mountain bikes have shifted to one-by drivetrains for simplicity.

The Suntour XCM coil spring fork gives you 100mm of front suspension travel that helps smooth out bumps and chatter in the trail. It also has a hydraulic lockout so you can improve your efficiency on pavement.

This coil sprung fork doesn’t have as much adjustability as a higher end air fork, and it’s not lightweight, but it works well for the price.

The Trek Marlin 5 Gen 2 comes with Tektro HD-M275 hydraulic disc brakes. If you’re looking at getting a budget mountain bike, this may be the first bike you’ve ever had with powerful hydraulic disc brakes, and you’ll be amazed by the power and modulation you get over other mechanical disc brakes or V-brakes.

Brakes are an easy-to-overlook feature for mountain bikes, but they make a huge difference in giving you confidence to ride fast knowing that you’ll be able to stop at a moment’s notice.

This bike comes with Bontrager alloy wheels. For this model Trek chose to have wheel size depend on the frame size. XXS comes with 26” wheels, XS and S come with 27.5” wheels, and M and above come with 29” wheels.

I think this is a pretty smart way to do wheel sizing for a bike like this. On small frame sizes, the rear wheel can be annoyingly close to the seat tube. Variable wheel sizing ensures that riders of all sizes have a frame and wheel size that feels easy-to-control.

The wheels are not tubeless compatible and use a schrader valve, so you’ll be limited if you’re looking to upgrade tires.

The Bontrager XR2 Comp wire bead tires on the Trek Marlin 5 are nothing special, but they work well for giving grip in a wide range of conditions. They aren’t particularly lightweight or aggressive, but they do the job.

Other Components

• The Bontrager alloy handlebar is a good width that gives you control on the trail or in traffic.
• The Bontrager Arveda saddle with steel rails is durable and comfortable on longer rides.
• The bike has a durable and lightweight Shimano aluminum crankset.

Competition for the Trek Marlin 5 Gen 2

At $750, the Trek Marlin 5 is at the lower end of the price range for mountain bikes. There are a lot of bikes to choose from in this category so it’s hard to stand out. The Marlin 5 does a good job of providing high-value features and components, but it isn’t anything unique in the category.

In my opinion, the Trek Marlin 5 is at the edge of the price cutoff where you can start to get a really capable aluminum hardtail for trail riding. Unfortunately, I think it falls on the wrong side of that cuttoff.

The Trek Marlin 5 is a perfectly functional mountain bike for everyday use and occasionally hitting the trails, but if you want to spend more time on singletrack and develop your skills, there are better options.

Read on to see some other options to consider, including two of the best mountain bikes you can buy if you’re on a budget: the Marin Bobcat Trail 4 and the Canyon Grand Canyon 5.

Trek Marlin 5 vs Marin Bobcat Trail 4

For a more trail-worthy bike at a similar price, the Marin Bobcat Trail 4 is a fantastic option that’s built for progressing mountain bikers. At $800, the cost is only slightly more than the Trek Marlin 5, while the design and components make this a more capable trail bike.

The Bobcat Trail 4 has the same coil spring suspension fork and hydraulic disc brakes as the Marlin 5 and comes with a super reliable Microshift Advent 1x9 drivetrain. This budget 1x drivetrain offers fantastic value with wide 11-46 cassette gear range and a clutched rear derailleur. This drivetrain will be a big upgrade for trail riding.

The biggest difference between these two bikes is in the frame and geometry. Marin has done a much better job of bringing progressive modern mountain bike geometry into this budget frame. The slacker head tube angle and longer reach will make the Bobcat Trail feel much more confident on singletrack.

Personally, I would definitely recommend the Marin Bobcat Trail 4 over the Marlin 5 as it has more capability to ride well on trails as you progress your mountain bike skills. For $200 more you can upgrade to the Bobcat Trail 5 for even more capability.

Trek Marlin 5 vs Cannondale Trail 6

The Cannondale Trail 7 is a popular entry-level aluminum hardtail that competes with the Trek Marlin 5 in price point and specs. There really isn’t too much differentiating these bikes. Both have basic but sturdy aluminum frames, 2x8 drivetrain setups, 100mm Suntour forks, and similar geometry.

One advantage of the Marlin 5 is that it comes with 29” wheels for size medium and above, where the Cannondale Trail 7 only has 27.5” wheels across the sizes.

Trek Marlin 5 vs Canyon Grand Canyon 5

If you can scrape together just a little bit more cash, the Grand Canyon 5 is an incredibly high-value mountain bike that delivers a lot more bang for your buck than the Marlin 5.

With a 1x12 Sram Shimano Deore drivetrain, a better suspension fork, better Shimano hydraulic disc brakes, and a lightweight aluminum frame with trail-ready geometry, this bike gives you a boatload of functionality that’s left off a mountain bike like the Trek Marlin 5.

Because of their direct-to-consumer model, Canyon is able to offer bikes at significantly lower prices than most manufacturers. The Grand Canyon is just $900. In my opinion, this is one of the best value hardtail mountain bikes on the market.

I mainly enjoy using my bike as a tool for exploration, I've done 50-mile all-day epic rides in the mountains and have been to some amazing places on my bike.

2021 Trek Marlin – Everything you need to know

2021 trek marlin - everything you need to know.

The 2021 Trek Marlin is a quality entry-level hardtail mountain bike. The updates it has had over its predecessor means that the new version is the best Trek Marlin yet.

It is an ideal bike for kids, commuters and those new to mountain biking. The 2021 Trek Marlin has proper mountain bike geometry, which is rare for entry-level mountain bikes. This makes it stand out from other bikes in this price bracket, as you can actually ride it on the trails and have fun. However, you need to be realistic about its capabilities. This is not the type of bike that you want to start hitting big jumps or very technical alpine terrain. But, if you are looking for a fun bike to take on relatively mellow trails, cross country rides or gravel tracks, the 2021 Trek Marlin is definitely up to the job.

All the 2021 Trek Marlin models have the Alpha Silver Aluminium frame. The 2021 Trek Marlin is a little lighter than the 2020 version, bringing it even closer to the X-Caliber, which is Trek’s cross country race bike. It has internal cable routing to protect the cables and to give it a nice and tidy look. If you decide to upgrade to a  dropper seat post , the internal cable routing is ready and waiting for it too.

Other Upgrades and Features

The 2021 Trek Marlin range has had some subtle changes. That is apart from the Marlin6, which is exactly the same as its predecessor, other than the new colour.

All of the 2021 Trek Marlin bikes have more colour options. This may not be your priority, but the new colours look really nice, and they have an excellent finish to them.

To make servicing the 2021 Trek Marlin easier, they are fitted with a threaded bottom bracket. This makes it easy to replace, and they creak less than push-fit versions.

The 2021 Trek Marlin 7 is more expensive than the 2020 version. Part of this reason is that Trek has fitted it with an upgraded RockShox Judy fork. This fork has a better feeling and dampening over the 2020’s XC30 fork. All the models in the range come with 100mm forks, disc brakes and a simple, durable drivetrain.

The Marlin 7’s drivetrain has also been upgraded to a Shimano Deore 10 speed. This upgrade makes it a 1×10 setup, which means that it will run smoother and you are less likely to drop your chain on bumpy terrain.

You get a much better range of gears with the 2021 Trek Marlin 7 over the 2020 version. This is because the cassette is an 11-46 tooth item, giving you easier pedalling on steeper climbs.

These features are a similar style to what you would find on a cross country race bike. This means pedalling is smooth and efficient. It will cope with trail centre trails with no problem.

One notable feature that the 2021 Trek Marlin has (as do all Trek bikes) is the lifetime warranty. This adds value for money to an already well-priced bike.

Things to Consider When Choosing

• The Trek Marlin is a hardtail bike aimed at people that want a bike for transport, as well as for having fun off-road on a budget. For riders that are planning on using it for just trail riding, the 2021 Trek Marlin should be fine, and you will have a lot of fun on it. But very rough terrain or downhill trails will be tricky. 
• You may find that you want better pedals. The ones you get are pretty basic, which is relatively standard practice for new bikes.
• Smaller frame sizes come with short-reach brake levers. These make it easier for riders with little hands to brake.

2021 Trek Marlin 5

The 2021 Trek Marlin 5 is the entry-level version of this hardtail. It is suited to riding daily as a commuter, but it also works well on the trails. This versatility makes it a good value for money bike at £440. Therefore, if you are looking for a reliable commuter bike that can hold its own on an off-road trail, this is worth considering. The light frame and efficient drivetrain make this an easy bike to pedal, while the hydraulic disc brakes give it plenty of stopping power.

The fact that the Marlin 5 comes with a kickstand should give you an idea of what it is designed for. But, it is a low priced mountain bike that is suitable as a mode of transport, no matter what the surface you are riding on is.

Specifications

2021 trek marlin 6.

At £530, the 2021 Trek Marlin 6 is a bit more of a proper mountain bike than the 5. It is actually an entry-level cross country bike. But, that doesn’t mean that you can’t use it as a commuter. To make it a good commuter, it comes with the mounts for a kickstand, mudguards and rack.

It has a wide range of gears for fast and easy pedalling on any surface you need to ride on.

This version of the Marlin has a suspension lockout feature. This means you can stop the suspension bouncing when you are riding roads or climbing, to make pedalling more efficient.

2021 Trek Marlin 7

The 2021 Trek Marlin 7 is a mountain bike that is at home on a commute as it is in a cross country race. It has a higher quality fork and components to reflect its racing ability. This is the flagship model of the Marlin range, with a RockShox fork equipped with a lockout and 1X10 drivetrain.

This bike is designed to take on long distances over smooth and rough terrain, either for fun or for racing. Priced at just £660, makes it an excellent value for money mountain bike.

i have recently purchased a marlin 7. it doesnt comue until august. im 35 and havent rode a mountain bike seriously since i was in my teens. im getting older and further from good shape so i decided it was time. i apreciate the piece i read on the drop seat. i had no idea there was such a thing. completely makes sense. My end goal is be riding downhill courses once im comfortable and in shape. If you have any other upgrades that would help me i would appreciate it. Thanks, Mike

Hi Mike.Its great that you are getting back into mountain biking. I think the best thing to do, is maybe spend money on coaching before accessories. Obviously a good helmet is essential, but there are other ways to protect yourself while riding. A good set of knee and elbow pads are great confidence boosters too.

Trek Marlin 5 Gen 2

Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A suspension fork, 2x8 drivetrain, and mounts for a rack and kickstand make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike. It's right for you if... You're new to the trail, and you're looking for a real mountain bike that doubles as a commuter—and you want it all at an exceptional value. The tech you get A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, 2x8 drivetrain, a wide range of gearing so you always have the right gear for your terrain, powerful hydraulic disc brakes, and a terrain-smoothing suspension fork with a lockout. The final word Marlin 5 is a great ride for all your adventures. But it's also versatile, and Marlin 5 is a popular ride on college campuses, because the rack and kickstand mounts make it easy to accessorize and haul a load. Why you'll love it - It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus, or just getting from A to B on any surface - Smaller frame sizes (XXS, XS, and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently - Marlin models in XXS through S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount - Rack and kickstand mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter - Like every model in the Marlin family, it's backed by Trek's lifetime warranty Wheel size: - Size XX-Small: 26-inch - Sizes X-Small – Small: 27.5-inch - Sizes Medium – XX-Large: 29-inch

Will my bike have a curved top tube?

Smaller frames (XXS-S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Trek Marlin 4, 5, 6, 7, and 8 Compared: Which One to Choose?

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

In this article, I’ll help you navigate the Trek Marlin mountain bike family by comparing the Marlin 4, 5, 6, 7, and 8. 

You’ll learn about the differences between each model, who they are best suited for, and more. 

Plus, I’ll tell you which model gives you the best value for your money to help make your decision easier.

KEY TAKEAWAY

Trek Marlin mountain bikes are ideal for beginners and intermediate riders. They are suitable for cross-country-like terrains. They have relatively short fork travel and no rear suspension, so I recommend avoiding too demanding terrains and technical trails. For those, check out Trek Roscoe .

Trek Marlin 4 vs. 5 vs. 6 vs. 7 vs. 8

The following table summarizes the main differences between all Marlins that belong among the Trek hardtail mountain bikes .

Marlin Pros & Cons Summary

I summarized the pros & cons of the Marlin series below.

Marlin Pros

• Affordability
• Availability in multiple sizes and colors
• Compatible with racks, kickstands, etc.
• Partially internal cable routing
• Lifetime warranty

Marlin Cons

• Unsuitable for demanding MTB terrain due to the short fork travel (100mm)
• Relatively heavy
• No full-suspension
• No dropper post (except Trek Marlin 8 Gen 3), Gen 3 models are compatible with dropper posts

Marlin Main Features

Let me now explain the most important features of the Trek Marlin bikes.

Frame and Geometry

All Marlin bikes have the same aluminum cross-country frame , available in many sizes and colors that vary between models.

The XXS-S sizes have a differently shaped top tube , which is curved to increase the clearance between the rider’s crotch and the frame. This allows riders with shorter legs to stand over the bike more comfortably, for example, when stopping.

The frames of Gen 2 Marlins have a standard cross-country geometry , which provides a comfortable riding position and easy pedaling uphill and downhill. It also gives you easy maneuverability and visibility.

On the other hand, it’s not quite suitable for steep descents and challenging terrain – especially without a dropper seatpost.

The Gen 3 Marlins have a trail geometry (wider wheelbase), which provides more stability, especially when riding downhill. It’s similar to the Trek Roscoe geometry .

Lastly, it’s worth noting that the bike’s partially internally routed cables improve its overall appearance.

One of the biggest limitations of Marlin bikes is their front fork suspension. These bikes are not primarily designed for challenging terrain but rather for those who want a versatile bike that can handle various surfaces.

All Marlin bikes have suspension travel of only 100mm , which is capable of absorbing small bumps. However, it’s not ideal for riding on rocky trails, and especially not for downhill riding.

Therefore, if you want a bike for more challenging terrain, choose one with longer travel (for example, the Trek Roscoe series ).

All forks of Marlin bikes have suspension lockout. Lock it when riding on smooth surfaces for less energy loss when pedaling.

Wheels and Tires

The wheel size varies depending on the frame size. Frames smaller than size S are equipped with 27.5″ wheels, which are more agile and accelerate faster than 29″ wheels. Frames size M and larger have 29-inch wheels, which are more stable and better at maintaining speed.

All models have the same rims (Bontrager Connection, double-wall) except for the highest model, the Marlin 8 , which has Bontrager Kove rims. The former rims are not tubeless-ready, while the latter are.

The same goes for the tires. The highest model already has tubeless Maxxis Ardent tires, while lower models have Bontrager XR2 Comp inner tube tires.

The groupset is one of the main areas where the different models vary, and it’s probably the deciding factor for many people.

They differ primarily in the number of gears . Modern mountain bikes mainly use 1X drivetrains , which are popular due to their simplicity for maintenance and shifting. They are also lighter than 2X or 3X groupsets .

On the other hand, they offer fewer gears, so you may not always find the ideal one for your preferred cadence.

I recommend choosing from the 1X drivetrains, which are available on Marlin 6 and higher models. This way, you won’t have to think too much about shifting and cross-chaining.

Another difference between the Marlin models is their brakes. The entry-level Marlin 4 uses mechanical disc brakes , while higher-end models have Tektro or Shimano hydraulic brakes .

Better brakes provide higher braking power. However, if you mainly ride on flat terrain leisurely, you don’t have to worry about a lack of braking performance.

Quality brakes are especially important if you plan on riding technical descents, so consider your riding style.

To learn more about disc brakes, read my article comparing mechanical and disc brakes .

Marlin frames have mounts for kickstands and racks , so you can easily install these accessories.

You can also use a Blendr stem , which is a mechanism that allows you to easily attach things like lights, speedometers, or bike computers.

The last detail is the lock-on grips that are easier to install and replace than slip-on grips.

So, which bike from the Marlin family is the best?

In my opinion, the Marlin 6 is the best choice because it has a modern 10-speed 1X Shimano Deore drivetrain and Tektro hydraulic disc brakes. Plus, it’s priced in the middle of the entire Marlin range.

Another option to consider is the Marlin 5 , which is similar but has a Shimano Altus 2×8spd drivetrain, is lighter, and more affordable.

On the other hand, I recommend avoiding the Marlin 4 because it uses the outdated 3X drivetrain. The value of the Marlin 8 is also questionable, as you can get mountain bikes with better components in this price range.

Trek Marlin FAQ

Trek Marlin mountain bikes are perfect for people who are new to mountain biking, recreational riders, and those who use their bikes to commute. Marlins are reasonably priced, versatile, and comfortable. They come in various sizes and colors, so you can always find the best fit. However, they have entry-level components and are not suitable for challenging terrain because their fork travel is short. Check out Trek X-Caliber and Procaliber families if you want a better XC bike.

Marlin bikes (4 to 8) differ mainly in components like the groupset, front fork, brakes, weight, and price. I recommend reading this entire article for more information and a helpful comparison table.

The geometry is the main difference between Trek Marlin Gen 2 and Gen 3. Gen 3 Marlins have a trail geometry, which means a wider wheelbase providing better stability. Gen 2 has a standard XC geometry. Marlin Gen 3 bikes use wider tires and different wheels and are heavier. They are also available in different colors and are more expensive (except for the Marlin 7 Gen 2 vs. Gen 3). Most other components, like the groupset, suspension fork, saddle, grips, etc., are the same.

Marlin mountain bikes are a great choice for those who need an affordable bike. They are versatile, allowing you to ride on different surfaces like paved roads with potholes, dirt, forest roads, and easy trails. Plus, they have mounting options that make adding accessories like racks and kickstands easy. The high-volume tires and front suspension provide a comfortable ride, better than what you’d get on a gravel bike , for example.

Marlin mountain bikes come with entry-level components that may limit their performance for serious mountain bikers. The groupsets are not as fast and effective, and the fork travel is limited to only 100mm. These bikes are also relatively heavy and don’t have a carbon frame option or a dropper post.

You mentioned you can get mountain bikes with better components for try price of the Marlin 8. Which ones come to mind?

Hi Andrew, Check out the Polygon Syncline C3 , which has a longer suspension travel and carbon frame (yes, it’s currently discounted), or Polygon Siskiu D5 , which is a full suspension MTB. 🙂 I hope it helps. – Petr

The Gen 3 Marlin 8 has a dropper post and many other gen 3 models have the holes to run a dropper.

Hi Brandon, Thanks for noticing that. I’ve updated the info. – Petr

Hi Guys, I am interested in Marlin 8, 3 gen. I live in Columbus, OH, what store location is the best for a test drive? Very Respectfully, Luis

Trek Marlin Buyer's Guide

Trek Marlin is a trail-worthy mountain bike that's tough enough for off-road adventures and versatile enough to impress dedicated commuters.  Read our guide to understand the ins-and-outs of this MTB, why it might be the best bang for your buck, and the differences between model options.

Trek Marlin Overview Trek Marlin Features Trek Marlin Models

Trek Marlin Overview

Who is a Trek Marlin for?

The Trek Marlin is durable, easy to outfit with gear and accessories, and at home on many types of terrain.  This makes it an ideal mountain bike for beginner cyclists looking for versatility at a good price point.  

Commuters will appreciate the frame mounts for a rear rack, 29" or 27.5" wheels for smooth and efficient pedaling, and 4" of front suspension to take the edge off the ride. 

The Marlin is capable on the mountain too.  It'll gobble up less technical XC trails like the Bonneville Shoreline Trail on the east bench in Ogden.

Why you might love a Trek Marlin

VALUE!  The Marlin is not only a high-quality and versatile mountain bike, it's also super affordable!  It's built with the best component spec per price point that ensures you won't outpace the bike as your cycling skills advance and your adventures get more technical.

Trek Marlin Features

Smart Wheel Sizing

Ride the fastest wheelset that fits. 26" wheels stay alive on the XXS size, while the XS and S frames roll with 27.5" wheels.  Medium thru XXL frames are equipped with the fastest 29" wheels.

Bike Mount Versatility

You'll appreciate the ability to accessorize with an array of features including a direct-mount for kickstands and rack/cargo mounts.  Bike packers and commuters alike can geek out over the mounting options.

The Marlin comes in seven frame sizes (XXS to XXL) to comfortably fit riders of practically  any height! For the smallest sizes, they've included unique fit features like a curved top tube for easier dismounting.

Race-Inspired Geometry

Trek engineered the Marlin to have the look of an XC-racing bike while prioritizing comfort for beginner riders.

Internal Cable Routing

Looks awesome!  No unsightly cables to be seen. Internal cable routing on the Marlin means you don't have to fret about dirt, grime, and inclement weather contaminating your cables.  

Marlin Gen 3 vs Marlin Gen 2

Whereas the Gen 2 Trek Marlins give riders a great balance between trail and street. the Gen 3 Marlins have been tipped towards the trail end of the scale.

• More tire clearance: Gen 2 Marlins have clearance for 2.2" tires while the Gen 3 models can fit 2.4" tires.  
• Internal dropper post cable routing: Gen 3 Marlins come with internal cable routing for dropper posts while Gen 2 bikes don't.  
• New rear ThruAxel: Gen 3 Marlins use a stiffer, more secure rear thru axle skewer.  
• Trail focused geometry: Gen 3 Marlins have a more trail focused geometry that includes a slacker head tube angle, a steeper seat tube angle, and a longer reach than the Gen 2 models.  
• Chain stay guard: All Gen 3 Marlins come with a full length chain stay guard to protectthe frame and keep things quiet on the trail.

The Trek X-Caliber is another solid value MTB but is actually an entry level XC race bike, and the Trek Roscoe is their agressive trail hardtail with more travel and bigger tire clearance.

Trek Marlin 5 Review: The Best Entry-Level Mountain Bike Around

I reviewed the entry-level Trek Marlin 5 bike and compared it to similar bikes - how did it fair?

As an experienced rider, I know what it takes to make a good bike, whether that's a top-of-the-range road bike or an entry-level mountain bike .

Overall I found the Trek Marlin 5 to have plenty of positives, including hydraulic disc brakes and Shimano derailleurs - honestly, it doesn't stop there!

For a more in-depth look, continue reading my Trek Marlin 5 review!

Table of Contents

Full Specification

Key features, alpha silver aluminum frame.

Trek Marlin 5 comes with an impressive alloy frame and things are kept tidy with the cables being internally routed.

For an entry-level bike, this is most surprising (but also welcomed!). It is rare to see internally routed cables. I love it, it makes the bike look sleek and it stops the cables from collecting dirt and becoming damaged.

SR Suntour XCE 28 Suspension Fork

It comes with 100mm of travel suspension so when faced with rougher terrain, it excels. There isn't a moment when things feel too demanding for the Marlin 5 thanks to the SR Suntour XCE 28.

Bontrager Arvada Saddle

Trek appears to like to kit their bikes out with Bontrager components and you won't hear me complaining! This saddle is there to give you comfort on long days riding and it works well for the commuter too!

Shimano Tourney 21 Speed Drivetrain  

It's common to see Shimano Tourney components at this price point. The quality is good and you have options!

You can either choose between a 3 x front derailleur or if you wish to reduce weight, you can opt for a 1 x Shimano Tourney at the front.

Which one should you choose?

Choosing the 3x will give you greater flexibility but more to think about. The 1x system will reduce the number of gears but allows you to spend more time focusing on your riding.

I favor 1x systems for their simplicity. When you're mountain biking, needing to changing the big ring can be one thing too many to get used to, especially if this is your entry-level bike and therefore your first!

If you're looking where the bike could be upgraded in the future then it could be the Shimano Tourney TY300 parts. Whilst they are decent and they are certainly a fantastic starting point, there are better options out there. A small upgrade in the future could see you finding it easier to climb hills.

Tektro HD-275 Hydraulic Disc Brakes

Hydraulic disc brakes on an entry-level bike? Trek has nailed it.

For beginner riders out there, hydraulic disc brakes are (for many, not all), the best type of braking system there is.

A slight touch on the brake levers is all you need to get a response...you don't get that from mechanical discs or rim brakes.

I came to fully appreciate hydraulic disc brakes going down Coll de sa Batalla for the first time, where I gripped on like my life depended on (it felt it did).

Since then. No turning back for me, there's only one form of brake system for me!

Bontrager XR2 27.5/29 x 2.2/2.0” Tires

Another Bontrager component!

These tires are of brilliant quality and they excel on mountain roads as well as gravel.

A downside to them is that they don't perform as well when things get muddy.

Wheel Sizes

There are different wheel sizes depending on the bike size you get.

The XS frame comes with 27.5" wheels.

Whereas, anything above that frame size gets 29" wheels.

At 5'4 in height, a lot of manufacturers would like to see me on 27.5" wheels, however, I ride 29ers on my MTB. I find this to be more comfortable and I don't feel hindered by having larger wheels.

What I'm saying is, test some bikes out, get a feel for what you like. Rules are there to be broken!

As I briefly touched upon earlier, the Marlin 5 comes with an alpha silver aluminum frame.

An alloy frame is a popular choice within this price bracket as it doesn't add extra weight to the bike as a steel frame would but it provides a good level of durability for a mountain bike.

Whilst you do get a good amount of durability, you have to factor in that this is a bike on a budget and it can't take on everything. It isn't designed for jumping so this is something to keep in mind if you're wanting a bike for serious trails.

All of the cables are internally stored in the bike, helping it to have a cleaner, more stylish look as well as improve the durability of the cables. 

The bike is available in three attractive colors, including black, green, and teal. These shades are uniquely beautiful and well-selected, so every cyclist will find the right color for them.

You can add a rear rack and kickstand to the Marlin 5’s frame, which makes this model a great choice for commuters, as well as adventurous cyclists. 

Do keep in mind that if this mountain bike was made of carbon fiber, it wouldn’t weigh the frame down as much, but the Trek Marlin 5 would come in at a much higher price point.

On Which Terrain Does The Trek Marlin 5 Perform Well?

We have to keep in mind that the Trek Marlin 5 is an entry-level machine so it isn't designed to be ridden by an expert rider, taking it on challenging trail riding.

Saying that the Marlin 5 is capable of rougher terrain and it works well as a trail bike. I'd always suggest that you check what the difficulty levels are before you hit the trail.

Bontrager Components

Let's clear something up for beginner riders getting into mountain biking.

Trek fits their bikes with 'Bontrager' parts. This is a Trek brand and made in-house.

For some brands, this isn't a sign of quality, yet this isn't the case here. Bontrager is a sign of quality.

On the Trek Marlin 5, Bontrager features a lot; the seat, seat post, handlebars, grips, and stem.

The stem is Bontrager alloy,  31. 8mm 7-degree Blendr compatible .

One of the best things about using these parts is that they are truly compatible across the Trek range of bikes.

As they are made by Trek, for Trek, the parts are made with the precise specification of their bikes so everything will fit seamlessly together!

For beginner riders, this is perfect as you won't need to give much thought about whether you're buying the correct parts.

[Check out this video from Trek for an overview of the range.]

Alternatives To The Trek Marlin 5

Without a doubt the Marlin 5 is feature-rich but how does this entry-level mountain bike compare to other bikes?

Trek Marlin 5 Vs Marlin 6

The first difference has to be the cost, the Trek Marlin 5 comes is quite a lot less than the 6 - this makes it an ideal first trail bike for those new to mountain biking, or those on a budget.

Having said that for trail riders looking to spend a bit more money, you do get a durable fork, a 2x drivetrain - including a better groupset and you even get a lighter bike!

One thing I do like with the Trek Marlin 6 is that there is the option to have either a man's frame or a women's. Whilst I find that women can ride men's bikes, it's nice to have an angled top tube.

You also get more options to customize certain features, so if you fancy a different wheel size, then the Marlin 6 can cater to that.

The standout benefit would be the upgrades with the fork - the fork on the 6 is a fair bit lighter than that on the Marlin 5. This reduces the weight of the bike, making biking trails or the commute easier.

Equally, the fork has a lockout and preload function so you are able to completely lock the fork to increase how efficiently you pedal - making your adventures easier!

Trek Marlin 5 Vs Giant Talon 3

The Giant Talon 3 has some good reviews and they're well deserved. In a lot of ways, these entry-level bikes are similar so are there any features that set them apart?

When compared to the Marlin 5, the Talon 3 seems to offer more traction when pedaling. This could potentially mean that as a rider, you don't feel as safe underfoot on the Trek Marlin and you could find that you're more likely to slip.

Though, the Trek Marlin 5 does give you a greater range of color types to choose from. So for trail riders who want to make their bike their own, the Trek could be the way to go.

There is a difference in wheel size too, with the Trek Marlin 5 you get 29" wheels, whereas Giant Talon 3 gets 27.5". Which one is better will come down to what you want from a bike.

The 27.5" wheels do mean the bike is lighter, which could be an appealing bicycle option to the commuter, beginners, or anyone who wants a bit more control!

Both hardtail mountain bikes have plenty to offer and the specifications are similar. For me, it all comes down to wheel sizes and the experience you want when you're cycling.

Trek Marlin 5 FAQs

Can i do tabletop jumps on the trek marlin 5.

The Marlin 5 is part of Treks' entry-level range and is not suitable to be taken on any type of jumps.

The wheels and tires are not designed to cope with jumps and could bend, even on a small jump so don't try it!

Can I Use Tubeless Tires On The Trek Marlin 5 bike?

Unfortunately not. The wheels aren't compatible with tubeless tires.

However, the wheels and tires are robust and suit mountain bikes well.

Does the Trek Marlin 5 have lockout suspension?

The Marlin 5 doesn't have a full lockout suspension. You do get a coil spring that has a pre-load adjuster though.

[Here are some ideas for when you really want to push yourself! 😉 ]

Final Thoughts

If you're wanting performance on a budget, there are plenty of plus points from this 29er.

The aluminium frame and Shimano Tourney components give the Trek Marlin 5 something to shout about.

Let's not forget the hydraulic disc brakes, making them ideal for dirt roads or a commute in any weather conditions. Braking at all speeds shouldn't be an issue with disc brakes.

Overall I have positive things to say about this bicycle. All terrains, mountains, trails, or commutes, the Trek Marlin 5 can do them all!

Review of Trek Marlin 5 Gen 2

Trek Marlin 5 Gen 2 is an entry-level trail bike ideally suited for beginners and recreational riders who need a dependable hardtail to hit the trails or use for a daily commute.

It features Shimano Altus 2×8 components, hydraulic disc brakes, an 80-100mm travel fork, and comes in four stunning paint jobs. 

The Marlin 5 has been one of the best-selling mountain bikes in this price range for a good reason, and we expect the Gen 2 version to follow in its steps.

• Hydraulic disc brakes
• 100 mm of front travel
• Progressive wheel sizing
• Heavy coil fork

Trek Marlin 5 Gen 2 Full List of Specs

Trek marlin 5 gen 2 full review.

If you’re considering buying your first mountain bike or treating yourself to a brand-new bicycle you’ll use as an everyday workhorse and commuter; the Marlin 5 Gen 2 is a solid choice.

The Trek Marlin 5 is an entry-level trail bike that has a lot to offer to trail lovers. If you want to figure out whether this bike is right for you, check out our detailed review below!

Quality Frame and Fork

The base of the Trek Marlin 5 Gen 2 is the brand’s Alpha Silver aluminum frame with a sleek design and stable geometry, suitable for various rider needs. This frame features internal cable routing that protects your cables from the elements and adds to the bike’s clean look.

Marlin 5’s frame is available in eight sizes , so you’re guaranteed to find the perfect one for your height. The SR Suntour fork is basic but provides 100 mm (or 80mm on the XS) of travel to take the sting off light trails. This fork has a coil spring which makes it a bit heavy, but it comes with a preload function, which is a nice plus.

Precise Hydraulic Disc Brakes

The star of the show on the Trek Marlin 5 Gen 2 is its Tektro hydraulic disc brakes . We are always pleasantly surprised to see them on bikes below $1,000, as hydraulic discs are a rare find in this price range.

Thanks to these hydraulic disc brakes, the Trek Marlin 5 Gen 2 is a bike that performs well in all weather conditions.

Compared to all other types, hydraulic brakes output the most power and provide the most precision. Trek has even gone so far as to install short-reach levers on the smallest frames.

2.20″ Tires and Progressive Wheel Sizing

Depending on how tall you are and which frame size end up going for, your Trek Marlin 5 will come with either 26″, 27.5″, or 29″ wheels .

The XXS frame has 26″ wheels, the XS and S frames come with 27.5″ wheels, and all other sizes are 29ers. Progressive wheel sizing and a curved top tube on the smaller frames decrease the standover height of the bike and ensure a much better fit for all rider heights.

The rims on all sizes are Bontrager Connection. They’re double-walled and have 32 spokes, which means they’ll take plenty of abuse. The Bontrager XR2 2.2″ tires are not tubeless, but they will give you plenty of grip on the three different wheel diameters. The 27.5″ wheels have extra clearance for 2.4″ tires. 

Shimano Drivetrain

Another positive aspect of the Trek Marlin 5 Gen 2 is that the entire drivetrain comprises Shimano parts. Sure, they are entry-level quality, but they offer more than enough performance and precision for the average beginner trail rider.

The Marlin 5 Gen 2 has 16 gears on a 2×8-speed drivetrain and comes with a complete Shimano Altus M315 drivetrain , which is one quality class higher than Tourney. This compares to the previous model’s more complex and heavier 3×7-speed drivetrain. 

The crankset is 36/22t with 160mm cranks on the XXS and 170mm on the other sizes. This crankset pairs with a 12-32t cassette. 

Dependable Bontrager Parts

Bontrager is Trek’s in-house brand that makes numerous parts and accessories. The Bontrager label on Trek Marlin 5 Gen 2 can be seen on the saddle, seat post, handlebar, grips, and stem.

Trek makes all of these parts specifically for their bikes, which means they are 100% compatible and perform for a long time without any issues. However, one of this bike’s downsides is that the headset is not tapered , so you might have a harder time upgrading the fork if you ever decide to do that.

Trek Marlin 5 Gen 2 Sizing Chart

• XXS — 4’5″ – 4’9″ / 135 – 145 cm
• XS — 4’9″ – 5’1″ / 145 – 155 cm
• S —  5’1″ – 5’5″ / 155 – 165 cm
• M —  5’5″ – 5’8″ / 165 – 173 cm
• M/L — 5’8″ – 5’11” / 173 – 180 cm
• L —  5’11” – 6’2″ / 180 – 188 cm
• XL —  6’2″ – 6’5″ / 188 – 195 cm
• 2XL — 6’5″ – 6’8″ / 195 – 203 cm

Who Is Trek Marlin 5 Gen 2 Best Suited For?

Like any other bicycle, the Trek Marlin 5 will not be a good buy for everyone. It is an entry-level machine mainly intended for beginner riders and those who do not take cycling too seriously.

Trek Marlin 5 Gen 2 should be shortlisted by beginner riders who are looking for their first mountain bike to commute or explore the dirt roads in their area.

If riding a bike is a weekend activity or a mode of transportation for you, then Marlin 5 will meet and exceed your expectations. You’ll be able to cover thousands of miles on it without any upgrades and explore farther than before.

However, if your idea of cycling is to hit trails as hard as possible and test your skills and limits, then you should save a bit more money and invest in a bike with slightly better components.

Is Marlin 5 Gen 2 a Good Buy?

The value for money you get out of this bike leads us to conclude that the Trek Marlin 5 Gen 2 is an excellent buy . For around $700, you get a high-grade aluminum frame that’s light, rigid, and durable (it’s even found on some  more expensive Trek bikes).

The drivetrain is entry-level, but the brakes are powered by hydraulics which is the best setup you can get right now.

For this amount of money, it’s a bargain. Therefore, if you’re the type of rider we’ve described, the Marlin 5 Gen 2 is a purchase that will put a long-lasting smile on your face if you go forward with it.

Thank you BIKEXCHANGE for helping me to make up my mind in purchasing the Marlin 5!

You’re welcome, Gwen! We’re happy we could help! Have fun with your new bike!

Great review. One question .. is this the old 5 or new 5 model? The new Marlin 5 design as I understand it being the old 5 plus aspects of Marlin 6 bike & otherwise that’s led to discontinuance of the Marlin 6 and only selling a Marlin 5 & 7 model going forward?

Much appreciated!

I am still riding my 2017 Marlin 6 its been too Hell and back. I live in the woods near Downtown Nashville 32 Thousand miles all pavement. riding in Hurricanes and Polor Vortex. Just got new breaks and Maxxis Hook Worm tires.I do circules around Gravel bikes.

Thinking about buying one of these and as an entry level rider seems like the best choice.

thanks for the review! it has made my mind up

The trek marlin 5 is a great bike. Bought for my wife, i sneak in rides. It isnt too heavy, the bigger 29″ tires are fun to feel a little bit higher off the ground. The braking system is fantastic and was a selling point for me.
