The Trek Procaliber 8 delivers cross-country speed with a dose of real-world versatility. Designed for riders who want race-level performance without sacrificing comfort, it strikes the perfect balance between efficiency and control. Its Alpha Platinum Aluminium frame is lightweight yet robust, engineered with modern XC geometry for agile cornering and stability on rough terrain. Internal cable routing keeps things clean, while hidden mounts offer options for racks and accessories when you need them.
Up front, the RockShox Recon Gold RL fork smooths out roots and rock gardens with 120mm of plush DebonAir travel and a Motion Control damper that lets you fine-tune responsiveness. The lockout feature helps you power through climbs with minimal energy loss.
A Shimano SLX and XT 12-speed drivetrain provides crisp, reliable gear changes across a wide 10–51T cassette range, giving you all the ratios needed for steep ascents and fast descents. The E*thirteen Helix crankset and Shimano BB-MT501 bottom bracket ensure efficient power transfer from every pedal stroke.
Control is backed by Shimano MT4100 hydraulic disc brakes, delivering consistent performance and modulation whatever the trail conditions. 29-inch Bontrager Kovee wheels, fitted with tubeless-ready Maxxis Rekon Race tyres, roll fast and grip confidently across mixed terrain, while the Bontrager Line dropper post adds stability and flow on technical descents.
Finished with a Verse Short saddle for all-day comfort and thoughtful finishing kit, the Procaliber 8 is built for riders who love speed, precision and the pure fun of cross-country riding. Whether you’re chasing personal bests or exploring local singletrack, this bike brings out your best with every ride.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
