The smarter hardtail

Procaliber sets the bar for hardtail speed and smarts. It's the fast, ultralight cross country ride that rules the singletrack, from the local race scene to the World Cup XC.

Procaliber's innovative IsoSpeed decoupler delivers uncompromising XC performance, efficiency, and an incredible ride feel. It's the fastest, smoothest, smartest hardtail on the trail.

IsoSpeed decoupler

Smooth means fast. Our innovative decoupler increases vertical compliance without sacrificing efficiency. You ride faster, longer, and stronger.

Doubly stiff: Boost148/110

Wider 148mm rear and 110mm front hub spacing on 29ers creates stronger, less flexy wheels and allows for wider tires, shorter chainstays, and more chainring options.

Light, lighter, or lightest

Choose Alpha Platinum Aluminum, OCLV Mountain Carbon, or the featherweight SL for World Cup-caliber performance.

Smart Wheel Size

One wheel size does not fit all. We put the right size wheel on every frame: 27.5˝ on 13.5˝ and 15.5˝ frames, 29er on 17.5˝ and up. Everyone wins.
