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 Frameset includes a headset and is designed for a PF92 bottom bracket, disc brakes and Boost148 wheels.

The final word

Procaliber AL is a lightweight aluminium mountain bike frameset 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.
