Cervelo R3 Ultegra Di2 Disc Road Bike
With Squoval Max tubing, the frameset of the Cervelo R3 is lightweight and stiff, climbing and accelerating with ease, and with a Shimano Ultegra Di2 groupset, this is a disc brake equipped road bike that leaves the rider wanting for nothing.
Cervelo's R-series road bikes are traditionally considered the marque's climbing bikes, but this R3 is no one-trick-pony. The lightweight frameset is beefed up in all the right places to deliver competitive stiffness that allows it to sprint with the best, accelerate with the slightest increase of effort, and corner like it's on rails.
The Shimano Ultegra Di2 groupset delivers electronic gear changes at the touch of a button, while the powerful hydraulic disc brakes make stopping reliable in any weather. Rolling on a set of Novatec R3 Carbon 35mm Disc wheels, you get performance and reliability with optimum rim depth for a variety of conditions.
