Trek Marlin 6 Review: Is This Bike Worth Buying?

What do you want from your MTB? Is it a bike that you can take to work every day? Something light that you can easily transport if needed, something with multiple speeds that will allow you to commute with ease?

Or are you after an adventure, a bike that you can have fun with? If you live near mountain trails, for example, you might want a bike that can handle a few bumps in the road. In that case, you’ll want something tough with great suspension that can easily deal with tougher terrain.

Bottom Line Up Front: So, we would recommend it overall ( you can pick it up online directly via Trek here ) – particularly if you’re on a tighter budget and you want to upgrade it later on down the line. It’s one of the best out of the box budget buys.  

The Marlin 6 is a GREAT budget pick to get started. An excellent all-around mountain bike, with room for plenty of cusomizations and upgrades later. Only if you need it.

How does Trek stack up against other companies?

Trek is known as a brand to be trusted. Thanks to years of quality craftsmanship and its long alliance with Lance Armstrong, Trek is considered to be a solid brand in the mountain bike space.

In terms of price, Trek offer a range of different options – from around $450 for the FX (a basic hybrid bike) right up to $12,500 for the Madone SLR 9 Disc brakes eTap suspension lockout (a state-of-the-art racing bike). The Marlin 6 is on the lower end of the price scale.

Trek are quite similar to Diamondback in their price range. Although Trek do offer a lot of expensive bikes (which is to be expected given their expertise), they have more budget options than Fuji and Cannondale.

What kind of bike is the Marlin 6 ?

Trek Marlin 6 is designed to be a multi-purpose real mountain bike: it’s built with mountain biking trails in mind, but it’s also great for commuters, with extra features like rack and fender mounts.

It could be the perfect choice for you if you want to hit the trails at the weekend, but also need a bike to commute to work in the week. It’s not built to go downhill or for heavy trails, however.

It’s also an entry-level bike (for mountain biking) – this means it’s a lot more affordable than some other bikes on the market.

The Main Features of the Marlin 6

Let’s take a look at some of the features of the Marlin 6.

What is the Trek Marlin 6 made from?

The Marlin 6 is made from aluminum, making it a pretty lightweight bike. There are seven sizes to choose from, so you should be able to find one that fits you. It comes in orange or silver.

What are the wheels like?

Depending on which size you buy, the wheels are either 27in or 29in – this is to help the larger bikes to have a smoother ride (with minimal impact to standover height). This is great because the larger wheels allow you to have a better riding experience on slightly rougher terrain. The wheels are heavy, however, which caused some users problems as they tried to pick up speed.

The wheels are Bontrager Connection 32-hole double-walled, and the tires are Bontrager XR2.

What other features does it have?

The Marlin 6 is designed to be able to handle lighter trails and cross country moderate terrain – so you won’t be able to hit the hardcore trails with this one. It does offer multiple gears (24 speeds / shift levers) with a rack and fender mount, however, which makes it ideal for commuting or mixed use riders.

How does the Trek Marlin 6 perform?

Some people found the Marlin 6 to be a little stiff and unresponsive, with the wheels reducing the responsiveness quite drastically at times. This makes it less comfortable to ride on trails, as it doesn’t seem to perform well on drops, with limited softening. However, in terms of riding on smoother, flatter terrain, it seems to perform nicely. A great entry level bike for mountain biking.

Check out how Marlin 6 Compares to Marlin 7.

What are the specs of the Marlin 6?

In terms of specifications, here are the main things you need to know:

• Fork – SR Suntour XCT fork, 100-mm travel fork
• Crankset – Shimano
• Derailleurs – Shimano Altus
• Brakes – Tektro M290 disc brakes (hydraulic disc brakes and brake levers)
• Saddle – Bontrager Evoke 1

What warranty will I receive if I buy it?

Like all Trek bikes, once you register it, you get a lifetime warranty against manufacturing defects.

Trek Marlin 6 is suited for…

• Riders on a tight budget but want a versatile crossover bike
• Those who want to try a bit of trail riding but also need a bike to commute to work/ride on flatter terrains (cross country mountain bike)
• A solid floor of great performance (from great brakes, excellent drivetrain, dropper post, silver aluminum alloy…)

Trek Marlin 6 is not suited for…

• Anyone wanting to tackle tougher trails
• Those that don’t want to upgrade/change parts on their bike to improve the riding experience

What do users think of Trek Marlin 6?

There are a range of views here. Many people find that it works very well on flatter ground, and they enjoy the large wheels and multiple speeds. Quite a few users decided to change the grips and pedals  (for different types of pedaling), which made riding the Marlin 6 a bit more enjoyable.

Generally, it’s considered a good bike for the price, and people say it is a good bike for customization – so if you want a bit of a ‘blank slate’, you can tinker with it to your heart’s content.

On the other hand, people found that braking and sudden turns put stress on the suspension fork legs, making them stick – and that it generally feels like a stiff, not very responsive ride on trails. Small jumps and dips in the trail were quite unforgiving for some people, which is a shame. A few people mentioned that the undampened suspension also made for a less comfortable riding experience on trails.

So, mixed opinions – it could work for you if you want to give trails a go, or if you’re willing to customize it, but it’s mostly suited for commuting (with kickstand and all).

The Pros and Cons of the Trek Marlin 6

Here are the best and worst bits about this particular model:

• Great price point ( see here for latest )
• Very customizable
• Handy for commuting
• Doesn’t ride as well on trails
• Can be a bit stiff and unforgiving

Frequently Asked Questions

Let’s take a look at some of the most commonly asked questions about the Marlin 6.

It weighs around 31.77lbs.

The maximum weight for riders is 300lbs.

People suggest you can ride the Marlin 6 on blue and green level trails with no problems. However, there may be more suitable bikes out there for you if you plan to hit the trails a lot.

Most users don’t recommend it – it can deal with small drops okay, but it isn’t designed for jumps.

Yes – it comes in a variety of sizes, too, so you should be able to find one that suits you.

Yes, there are two choices – orange and silver.

Where can I find Trek bikes?

What are the Best Trek Marlin 6 alternatives?

There are a few alternatives we can recommend if you don’t want the Marlin 6:

Diamondback Overdrive – This is a great bike at a similar price point to the Marlin 6. The wheels have great traction (making it great for trail riding), and it has a comfortable seat. It’s also very easy to assemble out of the box, making it a good choice for beginners.

The classic returns this year with 27.5” wheels, 24 speeds, a plush four-inch Suntour suspension fork, and powerful disc brakes. Big knobby tires grip every root and rock, keeping you confident and in control as you explore the trail. Whether you're a diehard hardtail aficionado or looking for a solid starter mountain bike, the Overdrive doesn't disappoint.

Trek Marlin 5   – This is great for beginner riders and offers similar features to the Marlin 6, including the alpha silver aluminum frame. You can get it for as little as around $500 , which is great if you’re on a tight budget. Again, it’s great if you want a bike that can handle the commute (commuter road riding) as well as some mild-to-moderate mountain bike trails (road and trail).

Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A front suspension fork with 100mm of travel, 21 speeds, 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.

Kona Blast – this is a tough bike that comes in at under $1,000 but can handle some tougher trails than the others on this list, thanks to the robust frame sizes (also aluminum frame) and excellent suspension. It can also handle some good jumps, too, so if you want to go on more adventures with your bike, it could be worth the extra money.

Conclusion – is the Trek Marlin 6 worth buying?

The Marlin 6 is going to appeal to a specific type of person. If you’re on a tight budget, you want a bike that can handle mild trails and you want to use it to commute to work, then the Marlin 6 is a great bike for you.

Also, if you’re willing to tinker around with it, you can slowly upgrade it to improve your riding experience over time. This is a great bike if you’re new to the MTB world and you fancy customizing a bike for the first time (as a more novice rider).

However, you do get what you pay for, and in this case, this budget bike doesn’t stack up very well against its more expensive counterparts. It’s not as fun to ride as other bikes we’ve reviewed, especially on rocky, bumpy trails. If you want a hard-wearing bike that you can have an adventure with, the Marlin 6 isn’t going to be for you.

Bottom Line: So, we would recommend it overall ( you can pick it up online directly via Trek here ) – particularly if you’re on a tighter budget and you want to upgrade it later on down the line. It’s one of the best out of the box budget buys.  

If you can afford to spend a few hundred more dollars and you don’t want to bother with customization, we’d recommend investing in a different model that is a bit more comfortable to ride such as the Diamondback Overdrive .

Trek Marlin 6 Gen 2 Review: Beginner’s Dream Mountain Bike

The Trek Marlin 6 2023 is the newest iteration of the entry-level XC hardtail family designed for light trail riding, gravel paths, fire roads, and mixed-terrain commuting. 

The 2023 Gen 2 model is the same as the Trek Marlin 6 2022, only with different colors and a new name. Trek overhauled its naming system for the upcoming year, referring to the models by the number of generations there have been. So the latest version of a Trek bike has the highest ‘Gen’ number.

This Trek Marlin 6 review will cover the bike’s main specs and highlights, answer some buyer questions, and provide our verdict on who should buy one. 

How Much is the Trek Marlin 6?

Trek Marlin 6 price is $850 and sits in the middle of the price range of the five Marlin models. The cheapest model costs $630, and the most expensive is $1,330. Alongside the 820, the Marlin is Trek’s most affordable mountain bike family.

• Shimano Deore 10-speed drivetrain
• Rack and kickstand mounts
• Progressive sizing 
• Low-performance coil fork

Trek Marlin 6 Gen 2 Full List of Specs

Trek marlin 6 gen 2 full review.

In this section, we will cover the main features of the Trek Marlin 6 Gen 2 and what makes it stand out in the sub-$1,000 MTB category. 

Trek Marlin 6 Gen 2 is available in four modern paint jobs that will suit any type of rider.

What Type of Bike Is a Trek Marlin 6?

The Trek Marlin 6 MTB is a modern-looking cross-country hardtail with a 100mm coil suspension fork, perfect for beginner mountain bikers. Unfortunately, the rudimentary suspension limits the Marlin 6 to relatively mild trails. Nonetheless, it makes an excellent day-to-day bike for commuting, transport, and leisure.

Alpha Silver Aluminum Frame

Trek uses its Alpha Silver aluminum frame for the Marlin 6. Thanks to the company’s consistent design and materials innovations, these frames outperform the similarly-priced competition in compliance and comfort. 

Internal cable routing means Marlin 6 looks sleek and neat, while it also protects the cables from excessive wear and tear.

The frame has quick-release axles, tidy internal cable routing, and mounts for a rack and kickstand, allowing you to equip the Marlin for commuting or bikepacking. One unusual feature of this bike is the curved top tube on the smaller models (XS, S) that lowers the standover height for a better fit. 

Is the Trek Marlin 6 Good for Jumps?

No, the Trek Marlin 6 isn’t good for jumps. Unfortunately, as a cheap hardtail, this bike uses a low-performance coil-spring Suntour XCT 30 fork with 100mm of travel (80mm on XS). This fork performs poorly on bumpy trails but is adequate for day-to-day riding and light off-roading .

Thankfully, the fork has preload and hydraulic lockout settings, but the headtube isn’t tapered, meaning it will be harder to upgrade.  

Shimano Deore 10-Speed Drivetrain

The standout feature for us is the Shimano Deore M4100 10-speed drivetrain. The Trek Marlin 6 is one of the only bikes with this hardware at $850 or below. In addition, an 11-46t cassette and 30t chainring provide plenty of gearing for steep gradients. 

Shimano Deore 10-speed drivetrain is a standard in this price range across the industry, as it provides plenty of gear range and smooth gear shifting.

Generally, sub-$1,000 mountain bikes have cheaper drivetrains that shift poorly and lose efficiency quickly. However, Deore M4100 is durable and smooth-shifting , and the single chainring makes it easier to maintain. 

Tektro Hydraulic Disc Brakes

Another excellent inclusion for a bike of this price is hydraulic disc brakes. Although entry-level, Tektro’s HD-M275 brakeset with 160mm rotors performs well at this price range and for a bike of this spec. 

Hydraulic discs allow you to stop safely in wet weather and with plenty of power and reliability in most situations. However, if you plan on tackling advanced trails, neither this bike nor the brakes are adequate. 

2.20″ Tires and Progressive Wheel Sizing

The Trek Marlin 6 has Bontrager XR2 Comp tires for handling hardpack trails, gravel paths, and pavement where traction is relatively predictable. These XC-style tires roll fast and provide decent grip but will slip and slide in wet trail conditions. 

Even though the tires are not tubeless-ready, they are wide enough to provide plenty of traction in varying conditions that come with modern mountain biking.

The XS and Small sizes of this bike have 27.5″ rims, while the others use 29ers. Progressive sizing makes the Marlin fit more consistently across rider heights. Unfortunately, the wheelset and tires are not tubeless-ready. 

Trek Marlin 6 Gen 2 Sizing Chart

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

Who Is Trek Marlin 6 Gen 2 Best Suited For?

The Marlin 6 Trek MTB is best for beginner mountain bikers who want to start learning the skills and techniques of the sport on light trails. In addition, cyclists who want a bike for comfortable day-to-day use, running errands, and mixed-terrain commutes will enjoy the Marlin 6. 

We recommend the Marlin 6 Gen 2 to beginner to early-intermediate mountain bikers who mostly stay on light trails and rough dirt and gravel roads.

Again, this bike is limited by its cheap fork, so if you want a bike to grow into and challenge your mountain biking skills, you may want to check out one of the higher-end Trek MTBs.

• Trek Marlin 4 Gen 2 Review
• Trek Marlin 5 Gen 2 Review
• Trek Marlin 7 Gen 2 Review
• Trek Marlin 8 Gen 2 Review

Is Marlin 6 Gen 2 a Good Buy?

We think the Trek Marlin 6 Gen 2 is a solid choice at just $850. The new-style frame and geometry make it look like the real deal, even if it can’t handle hard riding. 

Most of the Marlin 6’s components are excellent for the price range, including Shimano’s Deore drivetrain, hydraulic disc brakes, durable Bontrager tires, and a quality frame with solid ride characteristics. 

Don’t miss out on this excellent deal if you’re looking for a cheap do-it-all bike that’s at home on pavement, light mountain trails, and everything in between.

Q: How much does a 2021 Trek Marlin 6 weigh?

A 2021 Trek Marlin 6 weights M - 14.50 kg / 31.97 lbs (with tubes).

Q: What size 2021 Trek Marlin 6 should I get?

i purchased my 2021 trek marlin 6 size XL in the alpine blue a little over a year ago now. this bike is well worth the money that i paid for it. the finish of the paint is fantastik and that alpine blue is beautiful, i am always getting compliments about the color and the quality of the paint job. i do not take it on trails or thrash it, its just to beautiful. i use it mostly on the street. i have changed the tires to the SERFAS DRIFTER HYBRID TIRES, these tires are great for the street. they have a unique tire pattern and the rolling resistance is substantially reduced compared to the nobby maxxis tires the bike came with. the only disappointment that i find with this bike is the internal frame routing of the cables, when going over bumps the cables rattle a great deal, very irritating, and it makes the bike sound like it may be coming apart. other than that i would highly recommend this bike.

Trek Marlin 6 review

• Alan Muldoon
• June 25, 2019

With a few simple mods, the Marlin 6 could easily up its rating

Product Overview

Overall rating:, trek marlin 6 mountain bike.

• Top-rate frame quality, available in seven sizes Independent Shimano shifters
• Cable and chain rattle. Rear tyre is too skinny

Manufacturer:

Price as reviewed:.

The first of two 29er to make it into the sub 500 category, the Trek Marlin 6 certainly didn’t behave like a fish out of water.

>>> Best Hardtail Mountain Bike 2019: best reviewed mountain bikes under £375, £500, £750 and £1000

With a sleek new frame that offers stacks of standover clearance, its seat mast extending up like a dorsal fin, the Marlin is remarkably compact for a big wheeler. The quality of the Alpha Silver alloy frame is first rate too, where bridge less stays offer stacks of tyre clearance and a very forgiving ride.

With all of that real estate out back we wish Trek had occupied it with something meatier than the 2.0in Bontrager tyre. In fact, fitting the same 2.2in front tyre to the rear would do the trick.

Trek also missed a trick with the gearing on the Marlin 6. When you increase the wheel size you need to down size the chain rings to compensate. With the Trek’s close ratio 8-speed cassette the easiest gear on the Marlin was 24/32t, which is four teeth smaller on the rear and two teeth bigger up front than the Caliber 29er. If those numbers make your head spin, the takeaway message is that the gearing on the Trek will leave you light headed, gassed out and walking up steeper climbs on longer rides.

So the rear tyre and gears are both focused on towpath hacking and commuting to work. But the Marlin frame is so much more capable than that. It has pace and agility, and it really smoothes out the chatter. There are no real red flags in the overall build either, so with a few simple mods, the Marlin 6 could easily up its rating.

Specialized Rockhopper Vs Trek Marlin: Which Is The Best Hardtail?

The budget hardtail bike battle, Specialized vs Trek, two big brands that have been around forever.

Which one is the best bike for you?

In this article, we are going to compare their highest-end quality bikes together alongside their budget and mid-range models. As each brand offers quite a few bike builds for each model.

The Specialized Rockhopper bike is a heavy-hitting yet lightweight bike that boasts exceptional performance and versatility, regardless of the model or size.

This bike continues the Rockhopper’s 30-year tradition of striving for excellence and refusing to settle for anything less than the best. The frame is made of butted aluminum and comes with modern gearing, versatile geometry, and class-leading equipment.

Additionally, the Rockhopper offers innovative sizing and custom Rx Tune suspension, ensuring that it provides the best fit and handling performance for every rider, regardless of their measurements. The bike comes in different sizes, each paired with the optimal wheel size, further ensuring a perfect fit.

With performance-focused components at every level, such as RockShox forks, tubeless-ready rims and tires, 1x drivetrains on the Expert and Elite, and dependable Shimano parts, the new Rockhopper is an excellent choice for any occasion.

The Trek Marlin bike has always been a popular choice for new riders and seasoned pros alike, but now it’s better than ever.

With a revamped design that offers more trail confidence and sleek looks, this bike is ready to take you on any adventure. Its geometry is perfectly dialed to give you a confident, planted feel when navigating steep and bumpy trails, while still being easy to pedal back up for another lap.

A new Thru-Skew axle provides better rear wheel security, and full-length, full-coverage guards protect your frame and keep your ride quiet.

With big 2.4˝ tires that elevate traction and an upgrade-ready frame, this bike is ready for any challenge.

Plus, it’s available in every size from XXS to XXL, so every rider can find a well-fitted bike with Smart Wheel Sizing that scales the wheel size with the bike size for comfortable standover height.

The Trek Marlin bike truly is a bike for everyone.

But which bike is the best fit for you? That’s the question we’re here to answer! In this article, we’re going to take a deep dive into the Rockhopper and Marlin , comparing their features, benefits, and capabilities.

We’ll help you choose the perfect ride for your goals, whether you’re a seasoned rider looking for a new challenge or a beginner who wants to explore the world on two wheels.

Introducing the Specialized Rockhopper

As mentioned in this article on the best budget hardtail mtb for bike adventures the Rockhopper Expert is a popular bike amongst fellow bikepackers. Considered a cross-country mtb with 100 mm travel and weighing around 30 lbs or 13.6 kg.

It is a bike that has been around for 30 years resulting in the constant redefining of the relationship between value and performance.

The Rockhopper has somewhat of a cult following. If you are after an affordable cross-country mountain bike this might be the one. They have even cheaper options, however, the Expert is preferred if you are looking to go on bike adventures.

When it comes to long-distance endurance events this is a rather popular steed of choice!

Introducing the Trek Marlin

We have reviewed the Trek Marlin previously and here’s what we had to say.

The Trek Marlin 8 is a trail bike designed to boost your confidence on any singletrack, while also being equipped with features for everyday use. The perfect choice which competes directly with The Rockhopper Expert as a potential budget hardtail mtb for bike adventures.

With updated geometry, this bike gives you more control on challenging trails without compromising on comfort or convenience.

The Marlin 8 is built to last, thanks to its 12-speed SRAM shifting and upgraded RockShox air-spring suspension fork.

This progressive trail bike is perfect for building skills and taking on daily life, with premium features in all the right places.

Whether you’re hitting the trails or cruising around town, the Trek Marlin 8 is a bike that will help you progress and build your skills for years to come.

Price – Rockhopper vs Marlin

When it comes to price the Rockhopper offers the most affordable price with the entry-level Rockhopper model starting at $560 and the most pricy option at around $1,400. While the Trek Marlin ranges from $629 to $1,440

Weight – Rockhopper vs Marlin

The  Specialized Rockhopper weighs around 30 lbs or 13.6 kg  while the  Trek Marlin weighs around 31.51 lbs or 14.29 kg (this is for each bike’s highest-end model).

All different build options and models weigh differently. But from the numbers above we can see that the Rockhopper is approximately 700 grams lighter. And it makes total sense as this is the bike best for fast and aerodynamic riding

Tire Clearance – Rockhopper vs Marlin

When it comes to tire clearance the Trek Marlin fits up to 29er × 2.4″ mountain bike tires. While the Rockhopper has room for up to 29er x 2.3″ tires.

The Marlin comes stock with Maxxis Ardent (27.5 x 2.4″ or 29 x 2.4″ tires). While the Rockhopper comes with Ground Control (27.5 x 2.3″ or 29 x 2.3″ tires).

Gearing – Rockhopper vs Marlin

When comparing the high-end models, the Rockhopper and Marlin both feature an SRAM SX Eagle groupset which means an 11-50T cassette combined with a 30T crank resulting in a 17.45″ granny gear and 79.41″ largest gear for riding down hills. (this is when running a 2.3″ tire, you can expect this gear ratio to be slightly different with the Marlins 2.4″ tires) But this would be a small difference.

Suspension – Rockhopper vs Marlin

Suspension is where these bikes slightly differ again.

Both the high-end models feature the RockShox Judy fork, however, for some reason, the fork on the Trek Marlin has 80mm of travel while the Specialized Rockhopper has 100mm and all the other bike models, both for the Marlin and Rockhopper all have 100mm of travel.

The entry-level models for both bikes have the Suntour XCE28 fork and the mid-range models slightly differ. With the Marlin featuring a RockShox Judy and the Rockhopper with a Suntour XCM fork.

Handlebars, Seatpost, and other specs – Rockhopper vs Marlin

When it comes to handlebars both the Marlin and rockhopper have a 15 mm rise for Medium sizes and up with a 5 mm rise for the smaller frames.

The main difference when it comes to seat posts is that the Trek Marlin 8 Gen 3 has dropper posts while the Rockhopper doesn’t and all the other models we compared are all rigid.

Geometry – Rockhopper vs Marlin

Geometry can play a big part in the difference between how a bike rides and feels. It is definitely something to consider when buying a bike.

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

Here is where we see most of the differences in bikes. All the measurements below are in mm and are for both medium-sized bikes.

The main geometry specs that can paint the picture of the type of bike we are looking at are; stack/reach ratio, trail, chainstay, and wheelbase.

Firstly the stack/reach ratio for the Marlin is average when compared with other hardtail cross-country mtb with 1.44 vs 1.42 for the Rockhopper which is somewhat aggressive.

Suggesting that the Marlin is a more upright bike, in comparison, the Rockhopper is slightly more aggressive.

Chainstay is rather close with only 2 mm in difference with the Marlin boasting 438 mm vs the Rockhoppers 440 mm chainstay.

Along with this, the wheelbase length is 18 mm longer on the rockhopper. considering the chainstay is slightly longer also. I would argue that the Rockhopper may be the better bike choice, especially when it comes to geometry for bike adventures. The numbers mean in theory that it is the better-suited bike to allow for better-suited riding with gear loaded on the bike.

Now we’ll look at the trail. This tells the story of how each bike will corner and what the handling is like upfront.

Both trail measurements for the Marlin and rockhopper are considered very high. The Rockhopper has a 9.8 mm higher trail. When compared to the Marlin this means the Rockhopper in theory would have a slower, but calmer, steering response.

However, the Marlin is still rather high. But when compared together this favours the Rockhopper again as the more superior bike when it comes to bike adventures and carry gear. Especially in situations where you are climbing technical trails and need precision when steering.

Bikepacking – Rockhopper vs Marlin

The fact that bikepackers alike seem to have this cult following when it comes to the Rockhopper means that personally, I would recommend this bike over the Trek Marlin .

Even if the Marlin comes with a dropper post and the Rockhopper is rigid. And 1″ larger tire clearance on the Marlin .

When it comes to geometry it’s obvious that the Rockhopper is the superior bike out of the two.

And it’s also a bonus that the Rockhopper is slightly cheaper across the board.

To me, it’s a no-brainer to get a Rockhopper especially if you’re looking for a hardtail mtb for your next epic bike adventure.

The  Trek Marlin 6  is a quality introductory cross-country mountain bike with front suspension, 16-speeds and a wide range of gearing for easier pedalling on climbs. It's built in Trek's trail heritage, but also equipped with features like mounts for a rack and kickstand that make it a great choice for daily commuters.

If you're testing the waters of off-road riding, and want a real mountain bike at great value, with a wide range of gears to cover more ground on the road and trail.

• Lots of gears, so you can cover a lot of ground fast, without ever pedalling too gently or too hard
• Smaller frame sizes (13.5" and 15.5") have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently
• It has separate brake and gear levers (a feature that's common on more expensive mountain bikes) so you can fine-tune the positioning for comfort
• Rack and kickstand mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
• Like every Trek, it's backed by a lifetime warranty

2019 Trek Marlin 6 Build Highlights

• SR Suntour XCT 30 100mm travel fork with hydraulic lockout

5 things to do before every mountain bike ride

Do this quick pre-ride safety check before you hit the trails.

Product features

Will my bike have a curved top tube.

Smaller frames 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. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Fit for every rider

Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value

Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.

Rear kickstand mount

Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.

Rack mounts

Going for a long ride? Rack mounts make carrying accessories a breeze.

Blendr stem

Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

Internal cable routing

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

Mechanical disc brakes

Reliable stopping power in all conditions, including wet and muddy.

How tall are you?

To measure your height, stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inseam?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
