Trek Procaliber 6 Hardtail Mountain Bike 2025
The Procaliber 6 is a cross-country mountain bike built for hot laps and singletrack. It confidently rolls the fine line between race-ready and pocket-friendly with an alloy frame that's built with modern geometry for handling fast corners and rough sections of trail while keeping you ready to sprint up climbs. A 12-speed Shimano drivetrain and 120 mm RockShox fork seal the deal with all the gears and rock-smoothing comfort you need.
It's right for you if...
You want to dive into XC racing on a hardtail that's built to soar up climbs and stay composed through the rough stuff. You want to save some dough with a sturdy alloy frame, and don't mind upgrading your components over time.
The tech you get
A lightweight Alpha Platinum Aluminium hardtail frame with modern XC geometry and 148 mm boost spacing for stiff support under power. 120 mm of trail-smoothing front suspension from a RockShox Judy Silver fork with Solo Air spring and Turnkey lockout. Clean shifting 12-speed Shimano drivetrain that blends Deore and XT together, Tubeless-Ready Bontrager Kovee wheels, a Bontrager Line dropper post with internal routing and hydraulic disc brakes.
