Cervelo R3 (Ultegra Di2)

Throw down the gauntlet with Cervelo's ProTour-proven R3. Cervelo's huge Squoval carbon tubes transition into pencil-thin seatstays for a near-mythic blend of competition-shattering stiffness and cobble-dissolving control. The comfortable geometry and tapered front end add to the R3's amazing handling over all types of terrain, which is why it's won Paris-Roubaix multiple times. Beefy Squoval chainstays and Cervelo's BBright bottom bracket help channel every drop of power to the pavement, while Shimano's Ultegra Di2 drivetrain and Rotor's stiff 3D30 crankset offer incredibly accurate, smooth shifting. Adding to the speed and comfort are fast-rolling Mavic Aksium S wheels, a Fizik saddle, and quality components from FSA. Whether you're climbing the Alps, carving corkscrew descents in the Appalachians, or blazing past your riding buddies in the town-limit sprint, every ride on your R3 will be pure two-wheeled heaven.
