It's right for you if...
You like to go fast and also love the idea of a hardtail with frame tech designed to take the edge off rough singletrack. Speed is your main consideration, but comfort is right up there, too.
The tech you get
A lightweight Alpha Platinum Aluminium frame with IsoSpeed, a tapered head tube and internal derailleur routing. Procaliber AL Frame Set includes a head set, and is designed for a PF92 bottom bracket, post-mount disc brakes and Boost148 wheels.
The final word
Procaliber AL is a lightweight aluminium mountain bike frame set built in Trek's trail heritage. It's fast, responsive and it comes in at great value, but the biggest advantage is the trail-smoothing IsoSpeed decoupler, which takes the edge off fatiguing bumps in the trail so you can stay stronger for longer.
