Procaliber is a lightweight cross country hardtail that’s perfect for anyone who wants to ride fast and chase podiums. With Trek Procaliber, you get incredible hardtail efficiency with the trail-smoothing advantage of IsoSpeed.

The IsoSpeed advantage

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



Light, lighter, or lightest

Choose our best alloy option with Alpha Platinum Aluminum, or opt for a smoother, lighter ride with OCLV Mountain Carbon. Still not light enough? Procaliber SL models save an additional 200 grams and feature Trek’s Control Freak cable routing.


Smart Wheel Size

Smart Wheel Size ensures you’re on the fastest wheel that fits. Sizes 17.5˝ and larger get 29-inch wheels, while the smaller sizes get more proportional 27.5-inch wheels for a proper XC fit and optimum power and speed.


Race-ready parts

Every Procaliber features parts chosen to save weight and increas performance. All models have premium RockShox forks with remote lockouts, tubeless ready wheels with fast-rolling tires, and simple 1x drivetrains with carbon cranks on select models.
