Procaliber 9.8 SL is a performance hardtail mountain bike for serious XC racers. It has an ultra-lightweight frame with our lightest SL OCLV Mountain Carbon layup, trail-smoothing IsoSpeed, and a host of pro-level performance parts, including carbon wheels, a SRAM GX Eagle 1x12 drivetrain, and a lightweight RockShox SID RL fork. There's no getting around it: this bike was made to win.
