Overview
About this bike
A race 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 SRAM's XX1/X01 Eagle 12-speed drivetrain and SRAM Level TLM disc brakes, you'll race uphill and carve back down with expert precision. A carbon Cannondale bar, super fast HollowGram carbon rims, and tacky Schwalbe Rocket Ron EVO tires create a slick, race-ready hardtail package that's undeniable and distinctive both on the trail and off.
