Procaliber 6

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.

Technology

A better way to produce aluminium - Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make – this one included – had made the switch, driving a major drop in our footprint.
