Survival of the Fastest

The S5 is an aerodynamic road bike built for the fastest sprinters in the world. It is stiffer and more aerodynamic than ever before, while offering excellent comfort and ride quality. If you live for the exhilaration of going fast, the S5 will give you every possible advantage.

Aerodynamics

Integrated Aerodynamics

The S5 boasts substantial aerodynamic improvements over its predecessor. Full internal cable routing, a custom bar and stem, riding position, and special frame shapes work together to reduce drag and improve aerodynamics. The result: you go faster.

Stiffness

Maximize your Power

The best sprinters in the world need a bike stiff enough to handle the extreme forces they produce in the frantic sprint to the line. The new S5 Disc is significantly stiffer at the bottom bracket and head tube, without increasing frame weight.

Ride Quality

Confidence and Comfort

You'll feel the difference immediately. Frame stiffness and geometry work together for precise handling and pedaling efficiency. Frame lay-ups and tube shapes, along with tires up to 28mm wide, soak up road vibrations for a smoother ride.

Extended Seat Tube Cutout

Our Extended Seat Tube Cutout is a close fitting curve in the seat tube, which shields the leading edge of the rear wheel to significantly improve aerodynamic performance.

BBright™

Cervélo 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 lefthand chain stay. The benefit is increased stiffness and pedalling efficiency in a lighter weight frame. BBright™ is compatible with all major bottom bracket standards.

Less drag, more speed.

Aerodynamics are critical to engineering a fast bike: aero drag accounts for as much as 90% of the overall resistance affecting a rider. Using special frame tube shapes and design features, we improved the aerodynamics of the S5 Disc so you can reap the benefits of reduced drag.

The new S5 is 42 grams faster than its predecessor - that's the equivalent of 5.5 watts.

No wasted effort.

The stiffness of the S5 is a sprinter's dream. Using a combination of material, shape, and lay up, we engineered the S5 to be stiffer at the head tube, for stable and predictable handling, and at the bottom bracket, so that more of your power goes into turning the rear wheel.

13% increase in headtube (torsional) stiffness over the previous S5
25% increase in bottom bracket stiffness over the previous S5

Fit for you.

You'll be able to find your perfect fit on the S5, with six stem lengths, four bar widths, 5° of rotation, and up to 32.5mm of stem spacers.

The S5 is the pinnacle of "system thinking" whereby multiple Cervélo engineers are assigned specific areas of the bike's design in order to focus on perfecting each detail. The result is our stiffest and most aero iteration of the S-Series yet, all while retaining a superior level of ride quality and usability.

“The S5 tracks well, follows a line without an overdue amount of rider input, and tracks almost flawlessly in a straight line without your hands on the bar. Carving high-speed turns was a joy on this thing.”
