YOUR FIRST REAL MTB
Built to open the door to real mountain biking, with handling that feels composed, efficient, and confidence-inspiring from the first ride. Stable on loose terrain yet responsive under power, it encourages riders to progress onto faster, more technical trails.

MODERN XC GEOMETRY
Modern XC geometry creates a refined balance of stability and agility. A more confident front end improves control on descents, while an efficient pedaling position and 29-inch wheels help maintain speed smoothly across varied trail conditions.

TRAIL-READY PERFORMANCE
A 120 mm air fork brings more tunable front-end performance, while the dropper post adds confidence on descents and technical terrain. Shimano Deore 12-speed gearing and hydraulic disc brakes round out a more capable trail package.
