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.
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 the best in performance and reliability for every ride
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 Debon Air 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.
When you're ready to take on race day, reach for the Procaliber 8. This alloy hardtail has a speedy attitude with modern cross-country geometry that's dialled for hammering up climbs and keeps its composure on loose descents.
