favorite_borderWhy you'll love it
- It gets you into the world of cross-country riding and racing at a great price, and it's a mountain bike that can grow with you as your skills advance
- The sleek internal cable routing gives you clean looks, protects your cables and makes it easy to upgrade to a dropper post for even more capability
- The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade

Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Internal derailleur routing
Sleek ports at the head tube and near the seat tube let you route your derailleur cables through the frame to keep your bike running smooth and clean.
Going for a long ride? Rack mounts make carrying accessories a breeze.
