Cannondale's F-Si Women's 2 never learned the word "slow." This bike sports a super stiff, lightweight SmartFormed aluminum frame for a ride that packs trail-rolling zing. Ride-dialed geometry points, like nubby chain stays, 1.5-inch SI head tube, and Speed SAVE flex zones mean you'll sail through technical scrum and leave your friends wondering how you got so fast. The RockShox Recon fork has 100mm of travel to help you stick to your line, and the 27.5-inch Alex DC rims roll whip-quick over any obstacles that dare to cross your path. This cross country rocket's unheralded performance continues with Shimano's Deore drivetrain, a 20-speed setup that offers crisp, reliable shifting. And, total control is at your command with Shimano hydraulic disc brakes. Your XC domination will only excel with the inclusion of Cannondale's lightweight aluminum components. So, let the F-Si shrink your vocabulary by one word—"fast" will be its replacement.
