Overview
IT'S RIGHT FOR YOU IF…
You're after a carbon trail bike that keeps weight to a minimum without compromising on capability. You like to ride everything – long alpine climbs, rooty aspen slalom, fast XC singletrack, and you want a bike that can keep up on the ups and hold its own on the downs. Keeping things light with a carbon frame is important to you, and you want the light yet precise shifting of a Shimano XT drivetrain.
THE TECH YOU GET
An OCLV Mountain Carbon frame with a 4-way Mino Link lower shock mount for tweaking geometry and suspension leverage rate. A 130mm RockShox Pike Select+ fork with DebonAir spring, and Charger 3.1 RC2 damper, plus 120mm of rear travel from a RockShox Deluxe Ultimate RCT shock. A Shimano XT 12-speed drivetrain, Shimano XT 4-piston hydraulic brakes, Bontrager Line dropper post, and tubeless-ready Bontrager Line Comp 30 wheels.
