Product Information

Cervélo R5 Ultegra 8000 Road Bike 2018

The R5 is undeniably the greatest way to ride a bike, whether that's up the French Alps on when competing in your local criterium race. It's fast, incredibly lightweight and just as stiff and compliant. The R-Series range for years has left riders legs feeling just as fresh after their ride as they were before and the 2018 model only exceeds that feeling. Overall the new model is 34% stiffer which makes it the stiffest road bike Cervélo have ever produced whilst losing no compliancy. This version of the R5 has been kitted out with the brand-new Shimano 8000 Ultegra groupset which provides smooth, reliable shifting to get you through the harsh British winter months as well as the scorching hot European summers. 

Full Specification



With 21% more stiffness at the headtube and 13% more at the bottom bracket, the new R5 is our stiffest-ever road frame with rim brakes. But that’s far from the whole story: It also incorporates a stiffness-to-weight ratio that has been meticulously tuned to the attacking style of high-performance road cyclists.

Ride Quality

Elite road riders no longer equate comfort with soft, slow bikes. Vertical compliance can reduce fatigue and, in turn, boost power output. Wheel manufacturers’ wind-tunnel testing has also shown that wider tires can deliver aero benefits. For these reasons, tire clearance for the new R Series has been widened to 28mm. Combine this with a Cervélo-engineered aero seatpost, and vertical compliance is further increased while improving aerodynamics. At the same time, a new profit and handling geometry will have you charging down chicanes and attacking cobbles with complete confidence.


As well as the freedom to use a wider range of tire sizes, dozens of small, satisfying design details separate good from extraordinary: A subtle-yet-robust chain-stay protector, a sleek fitting top cap, an integrated Cervélo-engineered bar and stem that allows for internal electronic cable routing and easy computer mounting, an aero seatpost with integrated clamp and cover...the list goes on.
