Full of fast, built to last

Caution: X-Caliber will get you hooked. It packs all of Trek’s XC race hardtail experience into a light, fast, race-ready bike that pairs the right wheel size with each frame size.

Nothing beats the efficiency, simplicity and straight-up fun of an X-Cal hardtail in 29er or 27.5". Great for XC racing, marathons, 24-hour racing, or simply shredding singletrack.

  1. Smart Wheel Size One wheel size does not fit all. We put the right size wheel on every frame: 27.5” on 15.5” frames, 29er on 17.5” and up. Everyone wins.

  2. Race-ready spec 2x drivetrain options, suspension lockout, and Shimano hydraulic disc brakes mean you’re ready to roll right from the go.

  3. Light, precise race frame Highly refined Alpha Aluminium frame uses sophisticated tube shaping to minimise weight and maximise race-day performance.

  4. More sizes fit more riders Extended size range includes the small 13.5", the additional mid-range 18.5", and the extra-large 23" to better fit more riders.

Customer Review

What a great bike! I had been eyeing this bike for about a month and was looking for quality construction w/great design. This bike is cowabunga! It's like you're riding a monster truck with Porsche handling!
