Cannondale's best XC hardtail just got better. If going really, really fast on dirt in lycra is your cup o' tea, nothing lets you top 'em on the climbs and drop 'em on the descents like the F-Si. The World Cup edition features Cannondale's Hi-MOD BallisTec Carbon frame with stiffness-enhancing Si offset. The Lefty Ocho fork features no-bind needle bearings and extreme stiffness for pinpoint steering, now with a single crown design. ENVE's M525 carbon rims keep this rig at fighting weight, while the Schwalbe Racing Ray tires fly over hardpack and dig into sketchy corners. SRAM's XX1 drivetrain serves up 12 wide-ranging speeds, a carbon crankset, and crisp, precise shifting to give you the advantage on every part of the course. And, SRAM Level Ultimate brakes provide reliable, highly tunable braking power when you need it, so you can carry more speed and brake at the last possible second. Cannondale's carbon bar and seatpost keep you in control while adding almost no weight, ensuring that your race rig is sleek, lean, and ready to win.

The New Cutting Edge. This is the ultimate XC race bike. Ground-breaking suspension, aggressive geometry and feathery weight let you go full gas from the gun.
