A pure XC race mountain bike. Loaded with performance features that ensure victory all while weighing next to nothing.
A faster, better thru-axle. The slotted dropout design lets the axle stay in the hub for quicker, easier wheel changes. Compatible with standard 148x12 thru-axle hubs. It’s a better way thru.
Proprietary Ai offset drivetrain delivers super short chainstays for climb-winning traction and agile handling, without sacrificing mud/tire clearance or limiting you to single ring set-ups.
Confidently stable on hectic descents, yet quick and nimble everywhere else - OutFront Steering Geometry gives you the best of both worlds.
Cannondales premium high-strength, high-stiffness carbon construction. An advanced blend of intermediate, high, and ultra-high modulus fibers yields a frame that’s extremely light, durable, and lively.
In competition, up and down hills
