Procaliber 6 is a cross-country mountain bike built for hot laps and fast singletrack. It strikes the perfect balance between race-ready and budget-friendly with a modern alloy frame that handles tight corners and rough trail with ease—while still feeling snappy on the climbs. A 12-speed Shimano drivetrain and 120mm RockShox fork deliver all the gearing and comfort you need to keep pushing.

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.
