Whether you line up on a start line or are hunting Strava KOMs, Cannondale's Scalpel-Si Carbon 1 has high-speed competition and some extra get-up-and-go ingrained in every fiber of its super stiff, mega-efficient Ballistec HI-MOD carbon frame. Rocks and roots are 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. This XC rocket is dressed to the nines with Cannondale CZero carbon rims and tubeless-ready Schwalbe tires that track through buffed singletrack and chunky gnar with aplomb. Cannondale supplied their own HollowGram Si cranks, and paired them with an 11-speed Shimano XTR/XT drivetrain. You know what to expect: smooth shifts, a super wide 11-42 cassette, and the performance you expect from one of the most respected drivetrains in mountain biking. Shimano XTR brakes got invited to the party as well, and they brought along their smooth modulation and ferocious stopping power. A carbon handlebar, carbon seatpost, and stem from Cannondale, and a Prologo saddle, round out the contact points of this XXC monster.
