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.
