Cannondale's Scalpel Si Carbon 4 is a precise and dialed instrument of high-speed cross-country domination. The Ballistec carbon frame and oversize bottom bracket on the Scalpel come into their own when you need to step on the gas. 100mm of RockShox Monarch travel in the rear and Cannondale's 100mm-travel Lefty 2.0 Carbon XLR fork up front is a combo that chews up rocks and roots, transforming techy trail sections into a magic carpet ride. With Stan's NoTubes ZTR Rapid rims and tubeless-ready Schwalbe tires, it doesn't matter if you're riding chunky gnar or buttery singletrack, you'll accelerate and grip through loose corners like nothing else. Cannondale HollowGram Si cranks and an 11-speed Shimano XT drivetrain feature a wide gear range and smooth, reliable performance. Shimano XT brakes keep the party under control with power and unbelievably controlled modulation. A handlebar, seatpost, and stem from Cannondale and a Prologo saddle ensure comfortable, lightweight contact points.
