What makes it special
Thoughtful details. Big possibilities.
01Smooth means fast
Innovative IsoBow frame technology extends Procaliber's seatstays beyond the seat tube, allowing for increased vertical complicane that smooths trail chatter while reducing frame weight.
02Cool and composed
With a slacker head tube angle than most XC bikes and longer 120mm travel, Procaliber Carbon's calm demeanor encourges you to step on the gas.
03Float 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.
