  • Scalpel-Si: it's time to ...


Cannondale cuts to the front of the pack with their Scalpel-Si Black Edition. They pored over every detail to make it one of the lightest full-suspension cross-country bikes in existence, giving it a super stiff, mega-efficient Ballistec HI-MOD carbon frame, oversize BB30 bottom bracket, and a rear 142 x 12mm thru-axle. Techy terrain is no big deal with 100mm of RockShox Monarch travel in the rear. And up front, the 1.5-inch head tube is paired with Cannondale's 100mm-travel Lefty 2.0 Carbon XLR fork for razor-sharp handling and pinpoint line selection. And of course, this XC rocket is dressed to impress with utterly enviable ENVE carbon rims and tubeless-ready Schwalbe tires that spin up fast and grip like scared cats in the corners. Cannondale supplied their own HollowGram SiSL2 cranks, and paired them with Shimano's stunning 2 x 11-speed XTR Di2 drivetrain. It's all there: the fast, perfect shifts, powerful front shifting, and the performance you expect from what has become mountain biking's halo drivetrain. Shimano XTR brakes got invited to the party as well, and they brought along their smooth modulation and ferocious stopping power. An ENVE Carbon Sweep handlebar and carbon seatpost, Prologo saddle, and high-quality components from Cannondale round out the contact points. In the competitive world of cross-country riding and racing, the Scalpel-Si is your edge.
