Description

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 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.

- All-new lightweight Alpha Gold Aluminum frame delivers a phenomenal ride quality
- Shorter chainstays and Boost141 hub spacing for increased agility and clearance for wider tires
- Updated geometry and E2 tapered head tube for more confident handling
- Sleek internal routing protects cables and accommodates dropper post upgrades
