A cross country beast. The 2018 Cannondale Scalpel-Si Carbon 2 will have you sprinting up the mountains with its ultra lightweight full sus frame and parts spec, making a bike that’s near unbeatable. The Cannondale Scalpel-Si is one of the lightest full suspension XC bikes ever. The frame is built using BallisTec Carbon for strong, yet lightweight construction. The Ai offset rear end moves the drivetrain over by 6mm. This creates more room for tyre clearance, a wheel that requires no dishing, and a better chainline.
