For a great combination of ride quality, performance, and overall riding experience, the Cervelo R-Series difficult to match. It is a terrific all-rounder, as happy going up hill or down, sprinting or piling up the miles, and built out with Shimano's Ultegra Di2, precision shifting and value come right along with it. Finding the proper all-around road bike that can be ridden, raced, and fully enjoyed can be a fun experience, but Cervelo fans know not too look too far. The R-Series takes full advantage of it's SquovalMax tubeset, R-Series carbon disc fork, and the proven R3 crucial areas such as fit, handling and overall stability. The R-Series Disc frameset easily carries 28mm tires front and rear, and can just as easily be raced as it can be enjoyed on weekend 65 mile cruise. This is a true road bike.

Perhaps that is the best place to begin. The R-Series Disc is a road disc brake bicycle. Not an allroad, gravel or endurance bike. This design comes from the standard bearer R3, our best selling model for years. You get a tapered 1⅛" to 1½" carbon fork. There are 12/100mm front and 12/142mm rear thru-axle dropouts optimized with the Cervelo Indexed Thru-Axles w/ Lever. Flat mount standard caliper mounts fully integrate with the frame and fork, and yes the tire clearance is 28mm on a 25mm wide rim. These are features that actually suit the modern road bike preferences and are effective for improved handling, ride quality, torsional stiffness and overall performance that certainly carries onto the road.

The tapered, full carbon disc fork rides into the matched tapered headtube that, along with the main frame tubes, ensures exceptional torsional stiffness under any load. The always evolving square-oval, or SquovalMax tubeset that features a flatter shape system and improved aerodynamics is a modified version of the R5 but with a few changes, especially with the R-Series maintaining a round 27.2mm seatpost. The shapes and carbon lay-up improve the lateral stiffness by 18% over the first generation R3 disc frameset. The geometry has a lower standover height and improved toe clearance, improving overall stability, especially under braking forces from the hub mounted disc rotors. Wider tires at slightly lower pressures also improve handling and stability while reducing rolling resistance. As a sub 1000 gram frame in all sizes, the R-Series is still a superior climbing weapon- where the 18% stiffness really shines through, yet now is an even more capable descender and overall stable platform in all conditions. ...
