Smooth means fast
Innovative IsoBow frame technology extends Procaliber's seat stays beyond the seat tube, allowing for increased vertical complicane that smooths trail chatter while reducing frame weight.
Cool and composed
With a slacker head tube angle than most XC bikes and longer 120 mm travel, the Procaliber Carbon's calm demeanour encourges you to put your foot down.
Float and flex
Rather than mounting to the seat stay, the brake secures to an extension of the rear axle, allowing the seat stay to flex and damp vibrations from the trail without impacting braking consistency and modulation.
OCLV Mountain Carbon
Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.
You almost forgot your pedals
This bike doesn’t come with pedals because you'll have a better ride if you choose your own. See the pedal guide to find the best pedals for your riding style. Want pedals built for the race? We recommend clipless MTB pedals for control and efficiency.
Complete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.
Learn moreEasier internal routing
Integrated channels in the frame make it super-easy to route cable housing and brake hose so you get a clean setup with no hassle.
Watch the videoRapid Drive 108 rear hub
With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
