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.
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.
2x drivetrain options, suspension lockout, and Shimano hydraulic disc brakes mean you’re ready to roll right from go.
Light, precise race frame
Highly refined Alpha Aluminum frame uses sophisticated tube shaping to minimize weight and maximize race-day performance.
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.

You know you've bought a good piece of equipment when you immediately can appreciate an improvement in your riding. I've bought several bikes over the years but this is the one that moved me to the front of group of guys I ride with.
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!
