Trek Procaliber AL Frameset

Procaliber Alloy Frameset is the perfect launching pad for your next cross-country bike. It rolls the fine line between race-ready and pocket-friendly with modern geometry that's made for handling fast corners, and lightweight Alpha Platinum Aluminum that's tough, nimble, and ready to cut loose. Designed for a 120mm fork, this ride is ready to build up into your dream steed.

• You get modern geometry 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
• You can roll with up to a 120mm fork to get total trail capability
• You get to doll it up with all your favorite parts
• 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.

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.
