Details
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 4 features Cannondale's BallisTec Carbon frame with stiffness-enhancing Si offset. The RockShox Reba fork offers 100mm of travel to smooth your way to speed and control. WTB STX i23 TCS wheels deliver on strength and light weight, while the Schwalbe Racing Ray tires fly over hardpack and dig into sketchy corners. SRAM 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. Shimano MT500 hydraulic disc brakes provide reliable 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.
