Product Information

The original S2 design set standards that are now copied across the aero road segment. To redefine this model Cervélo had to imagine the perfect S2 experience—the last sprint on your Saturday morning group ride, or a long, solo straightaway at the edge of town—and make every part of that ride better. The new S2 offers an all-new frame and fork, with increased stiffness and refined aerodynamics. This is a bike that delivers maximum performance at a value-conscious price. Wherever your personal finish line is, Cervélo will get you there faster. 

Full Specification

16 years of aero road bicycle development have made the S-series the benchmark aero road bike. These bicycles are not only faster in the wind tunnel, but proven in the real world, and stiff enough to win professional sprint finishes. Cervélo pioneered the aero bike segment.


The S-Series is engineered to make you more efficient and comfortable—so you can be faster, whatever your speed. The focus on aerodynamics is visible in every aspect of the design—from the location and shapes of the TrueAeroTM tubes to the water bottle mounts. Once on the bike, its efficiency in transferring all of your power to the road will persuade—or demand—that you push it to road-blurring speeds. This performance does not wear off on climbs, making it an aero bike with the rare gifts of light weight and stiffness, one that climbs well and boosts your confidence descending. But speed also includes comfort—both in the carbon composite layup design and in the power saved through aerodynamics that keeps you comfortably in your zone, rather than off the back.


The S2 features Future-Proof Cable management which allows easy set-up for mechanical, electronic, or hydraulic lines, ideal if you want the opportunity to upgrade the frame in the future.
