Trek Procaliber with IsoSpeed

Fast with a side of smooth

The Procaliber is a game-changing XC race machine that pairs classic hardtail efficiency with the fatigue-fighting comfort of IsoSpeed for a ride that feels like first place. If you want to chase podiums on a hardtail that’s smoother, faster and more efficient than the rest, you want Procaliber.



The IsoSpeed advantage

Smooth means fast. Our innovative IsoSpeed decoupler increases vertical compliance and smooths trail chatter without sacrificing pedalling efficiency so you can ride faster, longer and stronger.



Light and fast frame

Procaliber’s OCLV Mountain Carbon frame and updated race geometry keep things light while providing speed-preserving stability on rough descents. A Straight Shot down tube adds stiffness for precision handling without any extra weight.

Big-wheeled benefits

Every Procaliber comes with fast-rolling 29-inch wheels, and all models are set up tubeless straight out of the box to save weight, provide better traction and protect against flats.

Rider-friendly features

Procaliber is packed with convenient features like hassle-free internal cable routing, improved Knock Block technology, and increased turning radius so you can take on tight corners with confidence.
