Enter one of the most sophisticated aluminum racing steeds ever smithed: the CAAD12 Ultegra is a speed demon waiting to be unleashed on your competition. Flow-modeled SmartFormed aluminum tubes yield lower weights, radical compliance, and unparalleled stiffness in CAAD12's frame, and race-inspired geometry is ready to contest the sprint. Race-worthy wheels from Mavic roll quick and are paired with tough Schwalbe tires so you'll be sticking corners and sailing smoothly. Shimano's 11-speed Ultegra drivetrain supplies the gears you need to attack on the flats and smoke your buddies up the climbs. And, Shimano Ultegra dual-pivot brakes bring things to a smooth halt when the need arises. High-quality handlebars and stem come straight from Cannondale, and Fizik has comfort locked down with the Arione R7 saddle.
