Cannondale's F-Si Carbon 3 is here to put you on a strict regimen of singletrack and wicked speed. The Ballistec carbon frame features Cannondale's breakthrough Asymmetric Integration rear triangle and drivetrain, delivering super short chainstays, an optimally dished rear wheel, and tons of mud clearance. New-school System geometry will rewrite your ideas of how XC bikes should handle. On the attack or railing switchbacks, the 1.5-inch head tube and Cannondale's Lefty 2.0 fork featuring 100mm of plush suspension travel, keeps your front wheel pinned to your line. For the go, Shimano's XT drivetrain gives the F-Si a lightweight, intuitive 11-speed setup designed with racing in mind. Plus, Cannondale's own Hollowgram Si crank and FSA chainrings ensure your competition will be left gasping. Magura hydraulic brakes scrub speed cleanly and easily, with responsive, well-modulated power right under your fingertips. Tubeless-ready Mavic Crossride Wheels, Cannondale's own stellar aluminum and carbon components, and a sleek Prologo Zero 2 saddle keep the F-Si Carbon 3 ready to rip.
