Cannondale's F-Si Alloy 1 is a mile-gobbling XC charger. The stiff, responsive SmartFormed aluminum frame features super short chainstays and tons of mud clearance for next level XC handling and maneuverability. The Lefty fork provides 100mm of plush suspension travel, keeping your front wheel pinned to your line no matter what the trail throws at you. Shimano's Deore/XT/SLX drivetrain gives the F-Si a competitive edge, with a lightweight, intuitive 10-speed setup designed with XC riding in mind. Cannondale's own Si crank and FSA chainrings will leave your competition gasping as you lay the power down. Shimano Deore brakes scrub speed cleanly and easily to handle descents and quick stops. Cannondale's aluminum handlebars and stem, and a sleek Stage 3 saddle make the F-Si a worthy steed that's as approachable as it is wicked fast.
