  • A better way to produce aluminum

    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

    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

    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.

Overview

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.
