The F-Si Carbon 2 is a hardtail like no other. Designed to let you out-kick them on the climbs and out-rip them on the descents, this ultralight rocket is your ticket to the top of the podium. Equipped with the Lefty fork, you'll out-corner, out-steer, and out-handle the competition, again and again. Get insane traction with super short chainstays, without being limited to 1X set-ups, or sacrificing mud clearance. Cannondale also equips the F-Si with fit-focused wheel diameters, to achieve the best possible fit for all riders. With Shimano XT/XTR shifting, and Magura hydraulic braking, you'll race uphill and carve back down with expert precision. A carbon Cannondale bar, super fast CZero carbon rims, and tacky Schwalbe Racing Ralph tires create a slick, race-ready hardtail package that's undeniable and distinctive both on the trail and off.
