Overview
About this bike
Kill on the ups and thrill on the downs with the world's best XC race machine. Welcome to XXC. Cannondale built their brand on aluminum frames and the Scalpel-Si showcases what they've learned along the way with low weight, out of the saddle stiffness, and snappy, responsive handling. 100mm of trail-smoothing travel is managed by a RockShox Monarch shock and Cannondale's Lefty 2.0 fork, a combo that chews up rocks and roots, transforming techy trail sections into a magic carpet ride. With Stan's NoTubes ZTR Crest rims and tubeless-ready Schwalbe tires, it doesn't matter if you're riding chunky gnar or buttery singletrack, they'll carve the turns and grip like nothing else. Cannondale Si cranks and a 2 x 11-speed SRAM/Shimano drivetrain offers a wide gear range, high-speed shifting, and rock-solid performance. Shimano Deore brakes are there when you need them, with power and modulation to spare. Cannondale components and a Prologo saddle round out the build and keep those contact points happy.
