Trek X-Caliber 7
Caution: X-Caliber will get you hooked. It packs all of Treks 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.
