The Walkthrough
favorite_borderWhy you'll love it
- It's more fun to be a better rider: Roscoe is so stable and forgiving, it's like an instant ability upgrade
- Even when the trail gets rough, the wide 27.5+ tyres deliver more confidence, traction and stability
- The dropper post lets you lower your saddle on the fly so its out of the way on descents
- The RockShox Solo Air fork can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
- The NX Eagle drivetrain gives you a wider range of gears for easier climbing in a simple 1x set-up
Features
Alpha Gold Aluminium
Our high-performance lightweight aluminium is continuously cold extruded and butted, and formed into manipulated tube shapes to balance strength and save weight.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Dropper post internal routing
Not ready for an internally routed dropper post now, but want to keep your options open? Select frames are equipped with the proper entry and exit points to accommodate internal routing for a Stealth seat post.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
WSD: fit for women
A great-fitting bike is a joy to ride. The better the fit, the greater your comfort, stability, power, and control. And nothing fits better than Trek WSD, Women’s Specific Design. Your perfect ride starts here.
