You're a mountain biker through and through, and want a single carbon bike for the best performance on everything from marathon races to gnarly descents and technical trail. You know you'll be riding this bike on every trail, so you're not going to compromise on frame material, suspension, or components. The tech you get A light and stiff full OCLV Mountain Carbon frame, 140mm FOX Factory 36 Float fork with GRIP2 damper, 130mm of rear travel with a FOX Factory Float shock featuring Trek's exclusive RE:aktiv with Thru Shaft, and a 1x12 SRAM X01 Eagle drivetrain. Plus, powerful Shimano XT 4-piston hydraulic disc brakes, Tubeless Ready Bontrager Line Carbon 30 wheels with a 54-tooth Rapid Drive rear hub for quick engagement, a Bontrager Line Elite dropper post, and a Bontrager Line Pro OCLV Carbon handlebar.
