The Trek Procaliber 8 is a fast, capable cross-country hardtail designed for riders who want to push the pace on singletrack, marathon events, and XC race courses. Built around Trek's lightweight Alpha Platinum Aluminium frame and paired with a 120mm RockShox Recon Gold RL suspension fork, it delivers confident handling, efficient climbing, and precise control on technical terrain. Its SRAM Eagle 70 T-Type 12-speed drivetrain provides crisp, reliable shifting under load, while Shimano hydraulic disc brakes, Bontrager Kovee Tubeless Ready wheels, and a dropper seatpost complete a build that's ready for everything from weekend trail rides to race day.
