Product Details

2017 Trek X-Caliber 8

Caution: X-Caliber will get you hooked. It packs all of Trek’s XC race hardtail experience into a light, fast 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, or simply shredding singletrack.

Key Features

- Race-ready spec: 2x drivetrain options, lockout, hydraulic discs
- Light, precise race frame for a fast, refined ride
- Ride the fastest wheel that fits with Smart Wheel Size
- Extended size range gives you a better fit for a better ride
