If you are always chasing your next fastest ride, the new S3 aero road bike will give you every possible advantage. We made the S3 more aerodynamic and with an optimized balance of stiffness and compliance. The result is increased speed, power transfer, and comfort.

Ideal For: Sprints / Criteriums / Solo breakaways

If you want more speed, you need to look at your aerodynamics. For the new S3 we spent hours in the wind tunnel, testing and refining designs. Full internal cable routing, a new bar and stem, and frame shapes work together to reduce drag on you and the bike, so you go faster.

Increased stiffness at the bottom bracket enables efficient power transfer, so your hard work is transferred to rapid acceleration. Stiffness at the head tube is critical to confidence-inspiring handling - you'll feel how stable and precise the S3 is when cornering and descending at speed.

You'll enjoy a smooth ride on the new S3. Specific frame lay-ups and tube shapes soak up road vibrations, helping to reduce your fatigue during long days. Combined with optimized stiffness and stable geometry, this is a bike that'll make you feel good and go fast.

The Cervelo frame, fork and handlebars are designed to hide brake and gear control lines from the wind for improved aerodynamics, without sacrificing usability or performance.

TrueAero combines specific tube shapes, sizes and design features to improve aerodynamic flow across the bike.  The application of TrueAero is tailored specifically for each of our bikes and their intended users.

Cervelo devloped BBright to take advatage 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 lefhand chainstay.  The benefit is increased stiffness and pedalling efficiency in a lighter weight frame.  BBright is compatible with all major bottom brack standards.

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 S3 so you can reap the benefits of reduced drag.

  • The disc model of the new S3 is 102 grams faster than its predecessor - that's the equivalent of 13 watts.

The lighter the bike, the easier it is to keep moving.  We focus on keeping our frame weights as low as possible, without sacrificing ride quality or safety.  Our engineers achieve this by combining the ideal mix of shapes, materials, and lay up techniques.

  • The disc model of the S3 frame is lighter than the current version by 68 grams.
