Why you'll love it

- OCLV Mountain Carbon main frame with alloy stays make for a bike that's light and trail-tough, Longer travel suspension and 27.5+ mid-fat tires are the perfect combination for traction, stability, and capability on rough trails
- Advanced spec including e-MTB-specific parts and Trek's RE:aktiv damper take this model to the next level
- It rides like a mountain bike because it is one: it has the same frame and suspension tech we've refined in our decades-long trail heritage
