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 F-Si Carbon 3 features Cannondale's 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. Stan's NoTubes Crest MK3 wheels keep this rig deliver on strength and flawless tubeless setup, while the Schwalbe Racing Ray tires fly over hardpack and dig into sketchy corners. SRAM's GX1 drivetrain serves up 12 wide-ranging speeds, and gets it power through a stiff TruVativ crankset, resulting in efficient power transfer and crisp, precise shifting to give you the advantage on every part of the course. SRAM Level T brakes provide precise braking power when you need it, so you can carry more speed and brake at the last possible second, and Cannondale's cockpit components and Fabric Scoop saddle keep you in control and race-ready.
