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
- 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
- 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 shift 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 accessorize, so your mountain bike can double as a rugged commuter
- Like every model in the Marlin family, it's backed by Trek's lifetime warranty
Features
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Extended size range
A wider range of sizes than the industry standard provides more option for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.
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.
Alpha Silver Aluminum
Our proprietary lightweight aluminum is continuously cold extruded to a single wall thickness for durable performance.
