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 Aluminum 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, post-mount disc brakes, and Boost148 wheels.

The final word

Procaliber AL is a lightweight aluminum mountain bike frameset built in Trek's trail heritage. It's fast, responsive, and it comes in at a 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 longer.

    Sizing & fit

    The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
