Procaliber 8 delivers all the trims of a race-ready XC mountain bike - RockShox fork, SRAM 1x12 drivetrain - on a lightweight, durable Alpha Platinum Aluminium frame with an IsoSpeed decoupler that smooths out rough trail. This is a high-quality hardtail with the key performance upgrades chosen to help you towards your fastest, longest rides ever.

You like the responsiveness of an aluminium frame, and would rather spend your money on better components than a full carbon frame. You want a ride that's lightweight and responsive, with an IsoSpeed decoupler and carbon seatpost, so you can pedal over rough spots with comfort and ease.

A durable and light Alpha Platinum Aluminium frame with IsoSpeed, SRAM NX Eagle 1x12 drivetrain with a wider-range GX Eagle cassette, Shimano MT500 hydraulic disc brakes and an advanced RockShox Recon Gold RL air fork with Motion Control damper and a remote lockout. Plus, Boost 148/110 Bontrager Kovee Comp wheels with a 54-tooth Rapid Drive hub for quick engagement and additional lightweight parts, like a Bontrager Pro OCLV Carbon seatpost and Montrose Comp saddle.

This is hands down the best aluminium hardtail we make. You're getting Trek's highest-grade Alpha Platinum Aluminium frame, the unique advantage of trail-smoothing IsoSpeed, a full-on race-worthy spec and quality suspension that you'd normally find on a much more expensive bike.
- The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesn't get beaten up by trail chatter
- You're putting your money into the parts that make a big difference in performance: an advanced frame, a wider range drivetrain with a lighter cassette and quality RockShox suspension
- The solid XC parts group will hold its own on the race course, but it's also going to hold up through everyday training rides
