At a Glance
The 2021 Cervelo S-Series Ultegra is a General and Endurance carbon mountain bike. It is priced at $4,500 USD and comes in a range of sizes, including 48cm, 51cm, 54cm, 56cm, 58cm, 61cm and a Shimano drivetrain. The bike is part of Cervélo's S-Series Ultegra range of mountain bikes.
The S makes every part of every ride better, whether during the final sprint on your Saturday morning group ride or your solo interval efforts on the edge of town. We’ve applied years of experience building the most aero bikes in the peloton to create a bike that delivers maximum performance.
When the UCI’s frame design rules changed we grasped the opportunity and pushed it to the limits. We made aerodynamic gains via a fully integrated cockpit for both mechanical and electronic builds. The S disc became a whopping 102 grams (13 watts) faster than its predecessor.
With such huge gains being made at this highly competitive performance level, the S reflects our commitment to bringing tangible aero gains within reach of more riders.
Elite Fit
Our Elite Fit is based on extensive observations and analysis of riders’ positions. It offers a wide range of positions for all athletes, from endurance riders to Pro-Tour racers, without compromising handling, comfort, or performance.
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.
BBright
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 pedalling efficiency in a lighter-weight frame. BBright is compatible with all major crank standards.
