Cervelo S3 Sizing


"I don't think there is any other bike I would buy"

- Outside magazine As the inventor of aero road bikes, Cervélo continues to lead the category. Aero road frames are the most difficult frames to design, as they have to be everything in one: aero, light, stiff, comfortable. Cervélo has worked to optimize this balance between the various requirements since its inception 13 years ago. For the S3, the engineers at vroomen.white.design used the R3 seatstay technology, rotated the stays 90 degrees and gave them a proper Cervélo aero shape. This reduces the weight, increases the vertical compliance and improves the aerodynamics. Sounds simple, but the structural design is extremely complex, which is why only Cervélo has such stays. The chainstays were also redesigned to optimize aerodynamics. Finally, the new ICS3 Internal CableStops offers another improvement to our cable routing technology.

Upgrades from S2

Lighter frame - The S2 is light, the S3 is amazingly light. Aero benefits without a weight penalty when compared to most frames, with the S3 you can have your cake and eat it too. More aero - The S2 has led the aero road bikes in windtunnel performance until now, the S3’s new seatstays and chainstays make it the newly crowned king.
