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. 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. Shimano XT Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on. Upgrade your pedals and love your bike more Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
