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

  2. Light, precise race frame Highly refined Alpha Aluminum frame uses sophisticated tube shaping to minimize weight and maximize race-day performance.

  3. 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.

  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.

What people are saying

This is my first 29er handles like a dream. It's light, fast, shifting very smooth, rolls almost over anything. Uphills no problem, did get two flats already thats what happens when your on the trails. Had this bike for 2 months already put 250 miles on it.
