The F-Si Carbon 5 is designed to let you out-kick your competition on the climbs and out-rip them on the descents. Equipped with a RockShox Reba RL fork, you'll get incredible stiffness and traction through the turns and over rough trail. Super short chainstays deliver nimble handling while clearing mud easily and allowing both 1x and 2x drivetrains. Cannondale also equips the F-Si with fit-focused wheel diameters, to achieve the best possible fit for all riders. With Shimano XT/SLX shifting, and Shimano Deore hydraulic braking, you'll race uphill and carve back down with expert precision. A Cannondale bar, durable WTB 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.
