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.

What people are saying

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!

This is my first 29er, and handles like a dream. It's light, fast, smooth-shifting and rolls almost over anything. Uphills are no problem. Did get two flats already, but that's what happens when you're on the trails. Had this bike for 2 months and already put 250 miles on it.
