A lightning rod in a world of synthetic fibers, the CAAD12 Disc Dura-Ace demands attention. Flow-modeled SmartFormed Aluminum tubes yield lower weights, radical compliance, and unparalleled stiffness in CAAD12's frame, and race-inspired geometry won't shy away from contesting the sprint. Race-worthy wheels and tires from Mavic roll quick through the toughest courses. Shimano's crown jewel, the 11-speed Dura-Ace group, shifts wicked quick, and is a true-blue gram-killer, and Shimano's hydraulic disc brakes provide smooth stopping power when the need arises. High-quality handlebars and stem come straight from Cannondale, and Fizik has comfort locked down with the Arione saddle.
