Trek Procaliber 8 2026 Mountain Bike

The Procaliber 8 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 SLX and XT drivetrain and 120 mm RockShox Recon Gold fork seal the deal with all the gears and rock-smoothing comfort you need.

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 Recon Gold RL fork with DebonAir spring, Motion Control damper and lockout. A clean shifting blend of 12-speed Shimano XT and SLX components, Tubeless-Ready Bontrager Kovee wheels, a Bontrager Line dropper post with internal routing and hydraulic disc brakes.
