It's right for you if...

You're new to the trail and want a serious mountain bike that doubles as a commuter—and you want it all at an exceptional value.

The tech you get

A lightweight Alpha Silver Aluminum frame, 21 speeds, a wide range of gearing so you never need to pedal too hard or easy on terrain that varies in elevation, hydraulic disc brakes that feel smoother than mechanical disc brakes, and a suspension fork with 100mm of travel—that's the same amount favored by most cross country racers.

The final word

Built in Trek's MTB heritage, and more than capable of taking on trail adventures. But it's also versatile. It's a popular ride on college campuses because the rack and kickstand mounts make it easy to accessorize and haul a load.

The Walkthrough

favorite_borderWhy you'll love it

  1. 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
  2. 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
  3. It has separate brake and shift levers (a feature that's common on more expensive mountain bikes) so you can fine-tune the positioning for comfort
  4. Rack and kickstand mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
  5. Like every model in the Marlin family, it's backed by Trek's lifetime warranty

G2 Geometry

Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.

Our proprietary lightweight aluminum is continuously cold extruded to a single wall thickness for durable performance.

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.
