Procaliber 8 is a fast, capable cross-country hardtail built to chase singletrack PRs and line up for race day. Its Alpha Platinum Aluminum frame delivers confident handling through tight corners and rough sections, while a 120mm RockShox Recon Gold fork smooths out the trail ahead. A wide-range SRAM Eagle 12-speed drivetrain, lightweight Bontrager Kovee wheels, and Shimano hydraulic disc brakes round out a build that’s ready to push the pace.
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.
