Trek Procaliber 6 29" MTB

The Trek Procaliber 6 is a fast, capable hardtail mountain bike designed for cross-country riders who value efficiency, control, and modern trail compatibility. Built around Trek’s Alpha Platinum Aluminium frame, it delivers a lightweight yet durable platform with race-ready geometry and clean internal cable routing for a refined look and long-term reliability.

Up front, a RockShox Judy Silver air fork with 120mm of travel provides confident handling and effective bump absorption, making the Procaliber 6 equally comfortable on flowing XC trails and more technical terrain. The Boost spacing and thru-axle design enhance stiffness and tracking precision, especially when pushing hard through corners.
