Push your riding to the next level on Cannondale's F-Si Alloy 2. The stiff, responsive SmartFormed aluminum frame features short chainstays for a lively ride that handles switchbacks and rough terrain. Cannondale's System geometry defines XC handling and speed, showcasing agility and maneuvering excellence even at your top end. With a 1.5-inch head tube and the RockShox Reba fork, you get 100mm of plush suspension travel to keep your wheel pinned in a variety of trail conditions. Shimano's Deore/XT drivetrain gives the F-Si Alloy 2 a competitive edge, with a lightweight, intuitive 2x10-speed setup. Shimano Deore hydraulic brakes scrub speed cleanly and easily, with responsive, well-modulated power right under your fingertips. Tubeless-ready Stan's wheels roll through obstacles, and Cannondale's own stellar aluminum components keep the F-Si Alloy 2 ready to shred.
