Trek Procaliber 8 - MTB Hardtail 2026 | mercury-lithium grey
The Procaliber 8 is a thoroughbred cross-country mountain bike that is built for fast laps and plenty of fun on the singletrack. The modern, race-ready geometry takes you through every bend at high speed and casually over rough trail sections, allowing you to sprint up challenging climbs with confidence. The 12-speed drivetrain with a mix of Shimano SLX/XT components provides all the gears you need for your XC adventures, while the RockShox Recon Gold fork with its 120 mm travel offers a comfort advantage that should not be overlooked.
A lightweight hardtail frame made of Alpha Platinum aluminum with modern XC geometry including 148mm Boost installation width for more stiffness and stability under load as well as a trail-smoothing RockShox Recon Gold RL fork with 120 mm travel, DebonAir spring, Motion Control damper and lockout. You also get a clean-shifting 12-speed drivetrain with Shimano XT/SLX components, Bontrager Kovee tubeless-ready wheels, a Bontrager Line dropper post with internal cable routing and hydraulic disc brakes. If you're standing at the start line on race day, you'd better be on the Procaliber 8. This aluminum hardtail has plenty of speed in its genes. It is based on a modern cross-country geometry that gives you plenty of speed on climbs and always radiates calm on challenging descents.
