Trek Marlin 6 is a beginner cross country bike with a 1x drivetrain, front lockout suspension, and men and women-specific models. Take it out on trails or fit it with a rear rack and turn it into a burly commuter.

Trek Marlin 6 Gen 2 is a multi-purpose cross-country mountain bike with big wheels and big aspirations. This bike is excellent to take down some trails when you crave adrenaline, but also to commute to work during the workweek.

This aluminum hardtailer has a lot to be proud of, especially when it comes to the geometry of the frame (loads of standover clearance), freedom of choice (seven sizes and two colors), and women-specific features. 

No matter if you are a man or a woman, if you’re looking for a ticket into the trail riding world, Marlin 6 is the real deal.

 

Suitable For Every Rider

Trek Marlin 6 is available both as a men-specific and a women-specific bike. First and foremost, in terms of components, they are 100% the same. Both have the same groupset, same brakes, wheels, tires, etc.

It seems that this year, Trek is breaking its tradition of bringing two separate models on the market. Instead, smaller sizes have a lower top tube that tips down.

This feature has always been the main characteristic of Trek’s women-oriented models, so the tradition stays the same in some form.

Trek Marlin 6 Main Features

Marlin 6 Gen 2 is a bike that offers high tech and high value at a low price. Beginner riders have a lot to be happy about and not too many things that could give them headaches.

Let’s check out the main features and the most important aspects of this bike, which make it one of the best deals in the entry-level cross country range.

 

Freedom of Choice

One of Trek Marlin’s main selling points is the freedom of choice it offers. First of all, Marlin 6 has options for both men and women

Size-specific wheels and tires give you the possibility to get the perfect sizing option for your height and inseam. The smallest frames (XS, S) come with 27.5″ wheels compared to 29″ wheels on the bigger frames.

Then there are colors. This year, there are four colors available, all of which are modern, attractive, and shiny.

The frame is equipped with eyelets for a rear rack, two water bottles, and a kickstand. Thus, you can personalize it to your liking.

XS & S have 27.5″ wheels and M & ML have 29″ wheels on the women’s version

 

Excellent Geometry

Marlin 6 Gen 2, like other Trek Marlin bikes, comes with an Alpha Silver Aluminum frame. This frame is characterized by low weight, comfort, and excellent geometry!

Namely, the two smallest frames (XS, S) have a drop in the top tube, which provides more standover clearance for shorter riders.

Moreover, this bike has a head tube angle of 69.3° to 69.5°, which is right in-between slack and steep. As a result, you’ll get the best of both worlds — swift and responsive maneuverability, as well as good rolling qualities.

 

Light and Efficient 1x Drivetrain

Marlin 6 is equipped with a 1×10 drivetrain that’s excellent for the trails. It’s lighter than a 3x setup and eliminates all the gears that you’d never use. You end up just all the gears that you need and none that you don’t

This drivetrain is fitted with Shimano Deore components. That is a slight upgrade from the previous Shimano Altus components.

As long as you adjust them properly, they’ll shift smoothly and precisely.

Front Suspension Fork with Lockout

Another improvement seen on Trek Marlin 6 compared to its cheaper brothers Marlin 4 and 5 is a better fork. The SR Suntour XCT 30 still offers 100 mm of travel, but comes with some additional functionalities.

Namely, this fork is slightly lighter than the XCE 28, even though it is also fitted with a coil spring. The good news is that it has both a lockout and a preload feature. Therefore, you can lock the fork completely if you’re riding in the city to increase your pedaling efficiency.

 

Powerful Hydraulic Disc Brakes

Last but not least, we should mention Marlin 6’s excellent hydraulic disc brakes. Tektro HD-M275 brakes are strong, precise, and durable. They’re coupled with 160 mm rotors both front and back.

These are dual-piston brakes characterized by easy adjustment and easy maintenance. When you adjust them once, you’ll be able to use them in all conditions and get the most out of them.

Who Is Trek Marlin 6 For?

As we’ve mentioned earlier, Trek Marlin 6 can meet the demands of different types of riders. It’s an excellent cross-country bike that’s suitable for trails, gravel, dirt, and any other unpaved challenge.

It also performs decently well on paved roads, even though it can prove to be sluggish due to burly tires. But you can use it for short urban commutes without any problems.

Marlin 6 is perfect for beginners and occasional adventurers. Even though trails are part of its nature, we wouldn’t use it for anything extreme, such as timed descents, jumps, drops, or rocky singletracks.

  1. Just purchased a Marlin 6 (AUSTRALIA) and could not be happier (52yr old)
    Haven’t ridden for 35yrs and feel very confident on the bike.
    Gearing is smooth and easy to use.
    Handles amazing with good front fork which has rebound adjustment & lockout.
    Will be changing out seat for something more comfortable and has no side stand but for the price point this is very minor and easy fixes.
    Tires are perfect for what I need and where I ride.

    1. Hi Shynjie,
      Of course. You simply need to consult your mechanic about that to make sure it is a good idea.
