Smooth means fast
Innovative IsoBow frame technology extends Procalibers seatstays 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 120mm travel, Procaliber Carbons calm demeanor encourges you to step on the gas.

Float and flex
Rather than mounting to the seatstay, 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
Treks mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Treks advanced engineering, and a higher standard of testing.

You almost forgot your pedals
This bike doesn’t come with pedals because youll 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 & efficiency.
