With a ride as fast as Cannondale's F-Si Carbon 2, you're going to be covering a lot more terrain. The HI-MOD 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 29 geometry redefines XC handling and speed, showcasing agility and handling in switchbacks or attacking rough terrain at high speeds. With a 1.5-inch head tube and Cannondale's Lefty 2.0 Carbon fork featuring 100mm of plush suspension travel, keeping your front wheel pinned to your line is easy no matter what the trail throws at you. Shimano's XT/SLX/Deore drivetrain gives the F-Si a competitive edge, with a lightweight, intuitive 2x10-speed setup designed with racing in mind. Cannondale's Si Crankset and FSA rings let you put the power down, and Deore hydraulic brakes scrub speed cleanly and easily. Tubeless-ready Stan's wheels, Cannondale's own stellar aluminum and carbon components, and a sleek Prologo Zero 2 saddle keep the F-Si Carbon 4 ready to rip.
