Speed, agility, handling

Highlights

Speed Release

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.

Traction Without Compromise

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.

Agility Meets Stability

Confidently stable on hectic descents, yet quick and nimble everywhere else - OutFront Steering Geometry gives you the best of both worlds.

BallisTec Hi-MOD Carbon

Cannondale's 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.

Connected

An integrated wheel sensor delivers hyper accurate speed, route and distance info, registers your bike, reminds you of needed service and more, all through the free Cannondale App.

SAVE micro-suspension

Flex zones and directional carbon layup allow the rear triangle and seat tube to absorb shock for better traction, higher speeds and minimized fatigue, whether seated or standing. Go faster longer.
