Cannondale's F-Si Carbon Women's 1 is a Terminator among XC-focused bicycles. Sure, it looks innocent enough—but beneath that understated exterior, there's a skeleton of super stiff, lightweight BallisTec carbon that rides like a fibrous dream. The Lefty 2.0 fork has 100mm of travel to help you charge into the rough and stick your line. 27.5-inch carbon CZero rims roll whip-quick over obstacles that dare to cross your path, and they're tubeless-ready, so prepare to shred! This cross country rocket's unheralded performance continues with Shimano's XT/XTR drivetrain, a 22-speed setup that offers unbelievably fast, nearly effortless shifting. Matched to Cannondale's own Hollowgram Si crank, the competition will have no idea how you got so fast. And, total control is at your command with Magura's MT-Race brakes. Your XC domination will only excel with the inclusion of Cannondale's lightweight aluminum components. So, when you fly off the starting line at the gun, don't worry: You'll be back.
