Whether challenging for the yellow jersey or just the local leaderboard, those who ride the S5 are united in one belief: sustained speed over great distances is what matters most.

The S5 represents a step even further into the space-age of race-legal aerodynamics. It is the pinnacle of what our engineers call "system thinking", whereby each member of the design team is assigned specific zones of the bike to develop. By focusing on airflow and stiffness in a defined area, the engineers are collectively able to perfect every minutiae of the bike.

The end result is the stiffest, fastest, most aero iteration of our most iconic model. All while retaining a superior level of ride quality and usability, in part thanks to the S5's fully adjustable bar and stem system.

Pro Fit
Cervelo’s Pro Fit offers our lowest frame stack heights to enable an aerodynamic riding position. The Pro Fit is the direct result of input from our pro racers who wanted to get their handlebars as low as possible for maximum aerodynamic advantage.

Aero Cable Management
The Cervelo frame, fork, handlebars, and associated components are designed to hide brake and shift control lines (mechanical, electrical, and hydraulic) from the wind for improved aerodynamics, without sacrificing usability or performance.

Floating RDH
Our two part floating rear derailleur hanger is designed to allow for easy alignment of the rear dropouts, ensuring that the rear axle can be installed quickly and simply every time. This design also incorporates the rear derailleur hanger and comes in different versions (threaded, RAT style) allowing you to easily update your frame and fork if standards change.

Cervelo developed BBright to take advantage of the fact that oversized frame tubes are stiffer and lighter. With the BBright system, larger-sized tubes are used in the seat tube, down tube, and left-hand chainstay. The benefit is increased stiffness and pedaling efficiency in a lighter weight frame. BBright is compatible with all major crank standards.
