Procaliber AL Frameset is a race-worthy cross country mountain bike with the unique advantage of IsoSpeed, a decoupler at the top tube/seat tube junction that provides additional compliance on rough trails. This Alpha Platinum Aluminum frameset is a wallet-friendly start to a lightweight XC build for your fastest singletrack rides ever.

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.

Why you'll love it
- The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesn't get beat up by trail chatter
- Internal cable routing extends the life of your cables and adds to the bike's sleek look
- This Alpha Platinum Aluminum frame is race-light and trail-tough
