You'll absolute fly up and down the trails on Cannondale's F-Si 2. This XC demon sports a super-stiff Ballistec carbon frame, complete with Cannondale's breakthrough Asymmetric Integration rear triangle, delivering super short chainstays, an optimally dished rear wheel, and tons of mud clearance. New-school System geometry redefines XC handling and speed, showcasing agility and handling in switchbacks and rough terrain at all speeds. With a 1.5-inch head tube and Cannondale's Lefty 2.0 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. SRAM's X01 drivetrain gives the F-Si a competitive edge, with a lightweight, intuitive 11-speed setup designed with racing in mind. Magura hydraulic brakes scrub speed cleanly and easily, with responsive, well-modulated power right under your fingertips. Tubeless-ready CZero carbon wheels, Cannondale's own stellar aluminum and carbon components, and a sleek Prologo Zero 2 saddle keep the F-Si Carbon 1 ready to fly.
