Trek Procaliber 6

Procaliber 6 is a cross-country mountain bike built for hot laps and singletrack. It confidently rolls the fine line between race-ready and pocket-friendly with an alloy frame that's built with modern geometry for handling fast corners and rough sections of trail while keeping you ready to sprint up climbs. A 12-speed Shimano drivetrain and 120mm RockShox fork seal the deal with all the gears and rock-smoothing comfort you need.

• You get modern geometry and 120mm of front suspension that keeps you in the attack on climbs and crushing confidently on descents
• It balances the accessible price of an alloy hardtail with the performance of its carbon cohorts
• The 12-speed one-by drivetrain gives you plenty of gears for hammering up climbs with the simplicity of a single shifter
• Its Tubeless Ready 29in wheels keep rolling resistance down while helping fight flats
• Internal cable routing keeps your ride quiet, reduces maintenance, and looks sleek

A better way to produce aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Shimano Deore

Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff, and the fun. With smooth riding, improved chain stability, and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
