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. 

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 .

Marlins differ only in components. I believe the Marlin 6 provides the best value for money because it has a modern 10-speed 1X Shimano Deore drivetrain and Tektro hydraulic disc brakes, and it’s priced in the middle of the entire Marlin range.

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

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) that provides more stability, especially when riding downhill. This geometry is similar to the Trek Roscoe .

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 a suspension travel of only 100mm, which is capable of absorbing small bumps. However, this is not ideal for riding on rocky trails, 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 Marlin bikes’ forks have suspension lockout. Lock them when riding on smooth surfaces to reduce 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 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 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 that are unsuitable 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, meaning a wider wheelbase provides better stability. Gen 2 has a standard XC geometry. Marlin Gen 3 bikes are heavier, have wider tires and different wheels, and are available in different colors. They are also 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 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.

The bike's geometry is designed to accommodate various riders, with frame sizes ranging from XS to XXL. The ML, L, XL, and XXL Bontrager Alloy sizes ensure shorter riders enjoy an optimized riding experience.

Suspension System

For tackling rough terrain, the Marlin 6 has an SR Suntour XCT 30 front suspension fork, providing 100mm of travel. This suspension fork offers a coil spring preload and hydraulic lockout, allowing riders to adjust the fork based on their preferences and trail conditions.

Braking System

Equipped with Tektro HD M275 hydraulic disc brakes, the Marlin 6 offers powerful stopping power and control, even in challenging conditions. These hydraulic disc brakes ensure consistent braking performance regardless of weather, giving riders confidence on the trails.

Drivetrain and Gears

The Trek Marlin 6 features a Shimano Deore 1x drivetrain, offering a wide range of gears for tackling a variety of terrains. This setup includes an easy-to-operate 10-speed rear derailleur and a long cage Prowheel crank, making gear changes smooth and efficient.

Wheels and Tires

Rolling on Bontrager Connection double wall rims and wrapped in Bontrager XR2 Comp wire bead tires, the Marlin 6 offers excellent traction and durability. The XR2 Comp tires are tubeless-ready, allowing riders to go tubeless for better traction and lower weight.

Other Notable Features

• The Trek Marlin 6 offers internal routing for cables, keeping the bike’s aesthetic clean and maintaining the lifespan of the cables.

The Trek Marlin 6 delivers exceptional performance and versatility, making it an ideal choice for mountain biking enthusiasts and daily commuters. With a lightweight aluminum frame, powerful disc brakes, and room for customization, the Marlin 6 is an excellent choice for anyone seeking a well-rounded bike at an affordable price.

Mountain Trails

As a mountain bike enthusiast, I found the Trek Marlin 6 an excellent choice for tackling mountain trails. With its frontend suspension fork and Tektro hydraulic disc brakes, I discovered it offers more control and comfort even on rough terrain.

Furthermore, the Marlin 6's Shimano Deore gears provide smooth and efficient shifting, making it easier to climb steep sections. Plus, the wider Bontrager XR2 Comp tires give improved traction – an essential factor when going downhill on loose surfaces.

Bontrager XR2 Comp tires:

• Size: 29 x 2.20 (medium to large frames); 27.5 x 2.20 (small to extra small frames)

Not only is the Trek Marlin 6 a capable mountain bike, but it also excels as a reliable commuter. With useful features like internal routing for a clean appearance and added durability, as well as rear rack and kickstand mount options, the Marlin 6 transforms into a versatile everyday ride.

The bike's powerful hydraulic disc brakes inspire confidence when commuting in changing weather conditions, as they offer consistent stopping power even in the rain.

Furthermore, the bike's coil spring suspension fork with hydraulic lockout enables a more comfortable and efficient pedaling experience, especially during long commutes on bumpy roads.

Rear rack specifications:

• Material: Aluminum

• Compatible with most pannier bags

Versatility

The Trek Marlin 6 balances its dual nature as a mountain bike and commuter, making it an ideal bike for anyone seeking a multi-purpose option. With frame sizes ranging from XS to XXL, it accommodates various rider heights, ensuring a comfortable ride for all.

Additionally, the Alpha Silver Aluminum frame features multiple bottle cage mounts, allowing riders to stay hydrated during long rides or carry a hydration pack when venturing off the beaten path.

One standout aspect of the Marlin 6 is its potential for upgrades. For instance, it's dropper post compatible, allowing riders to enhance their off-road experience further. It also supports a maximum width of 2.2 inches, so riders can opt for wider tires to tackle more challenging terrain.

Notable upgrades:

• Front suspension: RockShox Recon RL fork with 100mm travel
• Dropper post: Compatible with various seat post diameters
• Tires: Wider options available up to 2.2 inches

Upgrades and Accessories

As an entry-level mountain bike with several attractive features and specifications, customizing and upgrading the Trek Marlin 6 can significantly enhance your mountain biking experience.

Handlebars and Saddles

One of the first upgrades you might consider for your Trek Marlin 6 is a new handlebar or saddle that better fits your preferences. An example of a great handlebar upgrade would be the Raceface stem to improve the handling and responsiveness during your ride.

For saddles, various choices include weight, cushioning, and material like steel rails. Some notable options include saddles made of XR2 Comp or the more budget-friendly saddles made of Bontrager alloy. These provide comfort and durability for riders tackling rough terrains for extended periods.

Additional Mounts

To enhance both performance and convenience, add-ons and mounts are available on the Trek Marlin 6. One versatile component is the Blendr Stem , which allows for quick, secure attachment of items such as lights, GPS devices, and action cameras.

Moreover, for practical storage options, update your mountain bike with rear rack and kickstand mounts, accommodating pannier bags, or other storage solutions.

These mounts complement front suspension forks like the SR Suntour XCT 30, which improves the bike's ability to carry additional weight.

Upgrading pedals on mountain bikes can significantly improve your riding experience, especially for first-time mountain bikers. High-quality, durable pedals are available for a range of budgets, such as the affordable pedals that can be found for $40-50 or sometimes less.

Environmental factors and different riding styles mean that pedals will undergo different levels of wear and tear, so remember to maintain and replace your pedals as required.

Hydration Solutions

Numerous options are available for attaching water bottle cages and hydration packs. Consider, for example, incorporating either XS or ML L XL XXL Bontrager alloy cages that suit different frame sizes to ensure your water bottle remains secure and accessible throughout your ride.

Utilizing a hydration pack is another option, which not only provides water but also offers additional storage for essential tools, spare clothing, and snacks. Indeed, having the right hydration solutions can make the difference between a great ride and a miserable journey.

Maintenance and Warranty

It's essential to maintain your bike's chain. A well-kept chain ensures smooth gear shifts and improved performance. Remember to clean it regularly and apply chain lubricant when necessary.

Another vital maintenance aspect is caring for your bike's hydraulic disc brakes. The Trek Marlin 6 comes with powerful Tektro hydraulic disc brakes, which provide reliable stopping power even in rough terrain. Regularly check your brake pads for wear and replace them when needed.

Below are some additional maintenance tips to help prolong your bike's life:

• Clean your bike regularly to prevent dirt buildup in delicate components.
• Apply grease to your seat tube and other moving parts to prevent rust.
• Check your tires' air pressure and maximum width before every ride.
• Inspect cables for fraying or damage, and replace them when necessary.

Trek Marlin 7 Gen 2

Marlin 7 is where race-worthy mountain bikes begin. The smooth, lightweight RockShox fork and upgraded parts make this model the best choice for new riders who want a fast cross country hardtail that will hold its own against our higher-end race bikes. It's right for you if... - You're new to the trail but have serious singletrack aspirations, and want a race-worthy mountain bike with upgrades on the parts that make a big difference in performance, like a higher quality suspension fork and a wide-range 1x drivetrain. The tech you get - A light frame with internal shift cable and brake hose cable routing, a smoother-feeling RockShox Judy fork with a lockout, Shimano hydraulic disc brakes, and a simple 1x drivetrain that ditches the front derailleur for less clutter and easier operation. Don't worry, with the wide-range 11-46 cassette, you still get all the gears you need for clawing up climbs and blazing down descents. The final word - The RockShox suspension, wide range of gearing, and quality parts make it the best choice in the Marlin lineup for new mountain bikers who know they want a serious bike for their money. It’s fully capable of taking on off-road marathon rides and XC races. Why you'll love it - This is one of our most popular bikes for good reason. You get all the value, plus all the versatility—it's a totally race-worthy mountain bike, with rear rack mounts if you use it for commuting too - It's really fun to ride, and feels like a much more expensive mountain bike - Great suspension at an even better price - The 1x drivetrain gives you all the gears you need and none you don’t - Marlin models in XS and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount Wheel size: Size X-Small – Small: 27.5-inch Sizes Medium – XX-Large: 29-inch

Will my bike have a curved top tube?

Smaller frames (XS and 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 ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Due to supply-chain issues, Specs are subject to change without notice.

A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

Trek Marlin 8 Gen 2 Review

Trek Marlin 8 is the premium build from Trek’s family of cross-country hardtail mountain bikes. 

The Trek Marlin 8’s price is $1,330, a significant increase on the 7, but this is justified by air suspension, a tubeless-ready wheelset, and wide-range gearing, making it far more capable than the other Marlins. 

Beginner and intermediate riders can be confident aboard this bike, taking advantage of its race-ready characteristics. Alternatively, load it up with a rack and kickstand and use it as a mixed-terrain commuter. 

Our Trek Marlin 8 review will examine the bike’s strengths and weaknesses and offer a verdict on who should buy it. 

How Heavy Is the Trek Marlin 8?

The Trek Marlin 8’s weight is 29.1 lbs, almost three pounds lighter than the cheapest model. In addition, this bike is two to three pounds lighter than similarly-priced hardtails, which makes it notably faster going uphill. 

• Air suspension fork
• Tubeless-ready wheelset
• Lightweight for the price
• SRAM SX Eagle is a step down from the Marlin 7’s Deore M4100

Trek Marlin 8 Specs

Trek marlin 8 gen 2 full review.

Next, we’ll dive deeper into the components and features that make this bike stand out. But first, note the Trek Marlin 8 2022 is the same as the Marlin 8 Gen 2. 

Is the Trek Marlin 8 a Trail Bike?

When comparing the Trek Marlin 7 vs. Marlin 8, there’s a discernable difference in the ability to handle chunkier terrain. However, the Marlin 8 is still considered a cross-country bike , given the 100mm of suspension and XC-specific components. Most trail bikes have 130mm or more suspension travel.

RockShox Judy Silver Solo Air Fork 

Trek Bikes went for RockShox’s Judy Silver Solo Air suspension fork, which is the standout component of this bike’s setup. It’s relatively light, moves smoothly through the travel, and has decent small bump sensitivity.

The RockShox Judy air fork will easily give you your money’s worth if you decide to take Trek Marlin 8 on proper MTB trails.

Of course, it’s not going to handle big hits on rough trails with only 30mm stanchions and 100mm of travel  (80mm on XXS, XS), but it’s plenty capable on fast, flowy XC trails. It also has basic TurnKey lockout and preload adjustments.

Can You Add a Dropper Post to a Trek Marlin 8?

Yes, you can add some of the best dropper posts to a Trek Marlin 8. There is a hole to run the dropper internally through the top tube, but you will have to run the wire externally through the seat tube, as there is no hole at the bottom.

12-speed Gearing and Shimano Brakes

The Trek Marlin 8 mountain bike uses a modern 1×12-speed SRAM SX Eagle drivetrain, comprising a 30t steel chainring and an 11-50t cassette. This combination provides tons of range for the steepest climbs you’ll encounter.

SRAM’s SX Eagle 1×12 drivetrain offers a massive gear range to conquer virtually any hill you come across on your rides.

Although the gear range is better than the Marlin 7, we’re disappointed with the switch to SX Eagle, as it is a step down from Deore M4100 in performance and durability. 

Thankfully, Trek maintained the Shimano MT200 hydraulic disc brakes on this bike, ensuring reliable stopping power in all conditions. 

Tubeless-ready Maxxis Ardent Tires and Bontrager Kovee Rims

The Trek Marlin 8 takes a huge step up with XC-specific Maxxis Ardent EXO tubeless-ready tires. These are fast-rolling, race-ready tires for dry to mixed trail conditions. The three-compound design reduces rolling resistance and optimizes traction, while the EXO layer provides cut and abrasion protection. 

Running a tubeless setup gives the Marlin 8 MTB a massive boost in capability and comfort. Riders can run lower tire pressure to enhance traction, shock absorption, and control, opening up more trail opportunities. In addition, the risk of puncturing is greatly reduced. 

Likewise, the Bontrager Kovee tubeless-ready rims are a marked improvement over the Connection rims on the other four models. They’re lighter, more durable, and designed specifically for cross-country riding.

Who Is Trek Marlin 8 Gen 2 Best Suited For?

The Trek Marlin 8 is a proper XC bike for cross-country cycling , ideal for beginner or intermediate mountain bikers who want an affordable yet capable option to hit the trails. Likewise, this bike can double as a comfortable mixed-terrain commuter or bikepacking machine, thanks to the rack and kickstand mounts. 

Marlin 8 is compatible with a rear rack and even with a kickstand, so it can be a practical daily commuter or even a capable bikepacking machine.

The Marlin 8 is a broadly-appealing option as its versatility, reasonable price, and durability make it a great bike to develop your mountain biking skills on and even upgrade in the future.

Is Marlin 8 Gen 2 a Good Buy?

The Marlin 8 is an excellent buy at this price . You get Trek’s renowned reliability, air suspension, a tubeless-ready wheelset, Shimano hydraulic disc brakes, and a lightweight, compliant frame.

Trek gave Marlin 8 a premium finish, so the bike looks a lot more expensive than it really is, which is a nice plus if that’s something you care about.

It isn’t easy to find a hardtail at this price that handles cross-country racing, but this bike can put it up to the more expensive models. Trek Marlin 8 reviews online also paint an overwhelmingly positive picture, a testament to the quality and the value this bike offers in the sub-$1,500 price range. 

Choose Trek’s Marlin 8 if you’re looking for an affordable, race-ready XC hardtail that’s equally at home in the city.

Description

What size do you need.

• If you’re flexible, you might prefer a shorter head tube, so the smaller size might work out better for you. You can use a longer stem to make the reach more comfortable.
• On a bigger bike, the reach to the handlebars will be longer. This means that if you have proportionally longer arms, you might be more comfortable on a bigger frame.

Note : Please note that specifications are subject to change without notice, based on component availability and other factors.

The Marlin 6 is a cross-country mountain bike designed for efficiency with its locking telescopic fork and simple 1x drivetrain. It continues Trek's mountain bike tradition, but it also has features like mounts for a rack and kickstand, making it a great choice for adventurous riders.

Main features:

• The 1x drivetrain gives you all the gears you'll need and not one more.
• The smaller frame sizes (XS and S) have short brake levers better suited to riders with small hands so they can brake with confidence.
• Marlin models in XS and S frame sizes feature a curved top tube and lower standover height, allowing smaller riders to get on and off the bike more easily.
• Rack and kickstand mounts simplify attachment of accessories
• Like every model in the Marlin family, it's backed by Trek's lifetime warranty.
