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. The R-Series takes full advantage of it's SquovalMax tubeset, tapered carbon disc fork, and the proven, crucial characteristics that exemplified the greatness of the R3 bikes for years, such as fit, handling, compliance and overall stable power transfer and performance. 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 design.

Perhaps that is the best place to begin. When built up the R-Series Disc is a road disc brake design. Not an allroad, gravel or endurance bike. This design comes from the standard bearer R3, Cervelo's 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 now optimized with the Cervelo Indexed Thru-Axles w/ Lever. Flat mount standard disc caliper mounts for 140mm or 160mm rotor usefully integrate with the frame and fork, and yes the tire clearance is 28mm on a 25mm wide rim. These are features that actually suit today's 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 model 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.

A long standing key to Cervelo's R-Series bike performance has been the 79mm wide asymmetric BBright bottom bracket and design and oversized chainstays. Cervelo creates a balanced carbon lay-up in the fork and frame, applied throughout the SquovalMax tubeset to adapt the set-up for disc brake use. Cervelo adds their integrated Reduced Friction Bottom Bracket Guide, and Future Proof internal routing and interchangeable stop system for hydraulic, electronic or mechanical systems. A braze-on front derailleur tab is used, and the rear thru-axle dropout features a replaceable rear derailleur hanger. Cervelo specs their SP-19 27.2mm diameter carbon seatpost on this frameset, which best complements the ride quality and feel of the complete bike.
