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 TrueAero 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.
What goes into aero design?
The S5’s sleek design borrows much from the P-Series, including the extended seat tube cutout. From the dropped down tube to the shielding seat stays, all frame shapes are designed to smooth airflow over the entire bike and rider. Even the bottle cage location has been rethought to make it the fastest frame with one bottle or two. Add BBright™ technology and you get the best of aero engineering with maximum control and stability.
When the S5 was first unveiled to the public just days before the 2011 Tour de France, it didn’t take long to demonstrate its superior performance. Quickly boasting seven days in yellow in the Tour de France including two stage wins, the S5 embodies the perfect synthesis of speed and stiffness.
With an overall stiffness increase thanks to the BBright™ platform, this is not only a super-fast bicycle, but one that’s agile and responsive at top speeds, while smooth and comfortable on the toughest road surfaces.
Shielding Seat Stays
Hiding the rear brake from the wind, not from the rider. Properly formed seat stays hide the brake and improve air flow over the calliper.
Built for Bottles
Drinking is something that every rider needs to do. By taking this need into account during design, the overall result is a faster ride.
Positioning the down tube perfectly saves drag on the system by taking into account the interaction between the front wheel and the frame.
BBright optimizes system stiffness and weight while allowing for the largest range of crank compatibility in a modern press fit system.
Extended Seat Tube Cutout
Maximized extended cutout that smoothes airflow from frame to wheel, yeilding one of the largest single reductions in aerodynamic drag.
