Trek Procaliber Gen 2 Mountain Bike - 2024, Medium

The 2024 Trek Procaliber Gen 2 is a lightweight, race-bred hardtail built for modern cross-country speed with added compliance for rougher courses. Featuring Trek’s updated OCLV Carbon frame, it retains the signature IsoSpeed decoupler, which allows the seat tube to flex independently—reducing fatigue without sacrificing pedaling efficiency. With progressive XC geometry, internal cable routing, and Boost hub spacing, the Procaliber Gen 2 is designed to climb efficiently, descend confidently, and perform at its best in everything from local races to marathon epics. It’s a sharp, capable choice for riders who want the precision of a hardtail with a smoother ride feel.
