Mission Pro

Throw a leg over a Mission Pro 27.5 and you will instantly know you’re on a high-level piece of equipment. Packing 160mm of point-and-shoot full suspension travel, this 27.5” wheeled All Mountain bike wants to tear into rough, steep terrain, looking for hits and drops that would have the amateurs searching for a B-line. The KnuckleBox suspension never backs down, and the Shimano XT disc brakes are on hand to make sure things never get too rowdy. The FOX Float CTD suspension reduces pedal induced motion without compromising small bump compliance. When it comes time to pedal again, this platform will deliver you to the top efficiently and comfortably, so you have more energy for another rip back down.
