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.

The Walkthrough

  1. 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
  2. It's really fun to ride, and feels like a much more expensive mountain bike
  3. Great suspension at an even better price
  4. The 1x drivetrain gives you all the gears you need and none you don’t
  5. 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

Will my bike have a curved top tube?

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.

High tech, high value

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.

Fit for every rider

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.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
