The 2025 Trek Procaliber 6 Hardtail Mountain Bike 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.

The Procaliber 6 is built around a lightweight Alpha Platinum Aluminium hardtail frame with modern XC geometry and 148 mm boost spacing for stiff support under power. 29" wheels are used on all frame sizes for maximum speed.

The Procaliber 6 comes with 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.

This bike is perfect for

Mountain bikers who want a hardtail that's built to soar up climbs and stay composed through the rough stuff. The Procaliber is ready to be used for XC racing or fast singletrack rides.
