After years of research and testing on the road, in the lab and in the wind tunnel, we’ve redefined the classic road bike by revolutionizing three interconnected factors — comfort, fit, and handling/stability — while continuing to push the aero envelope with new Squoval Max tube shapes.
With 18% more stiffness at the headtube and 26% more at the bottom bracket, the new R5 Disc is our stiffest-ever road frame. And it gets better: By integrating the latest disc-brake technology, lateral fork stiffness has been boosted even further. But that’s far from the whole story: The R5 Disc also incorporates a stiffness-to-weight ratio that has been meticulously tuned to the attacking style of high-performance road cyclists.
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 aero. At the same time, the latest disc-brake technology, and a new pro fit and fine-tuned 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: Helpful thru-axle installation graphics, a subtle-yet-robust chain-stay protector, a sleek fitting cap, a stem that allows for internal electronic routing and easy computer mounting, an aero seatpost with integrated clamp and cover…the list goes on.
