Product Details

Cervelo S3 Disc Ultegra DI2 2019 - Aero Road Bike

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

The S3 Ultegra is the latest incarnation of a style of bike Cervélo pioneered and perfected - the aero road bike.

This Cervélo aero road bike is measurably faster than a regular road bike while being strong enough to handle the worst cobbled roads.

To make it perfect, the Cervélo S3's optimised carbon layup and its skinny seat stays deliver a level of engineered-in comfort and stable handling, previously absent from regular aero bikes.

Key Features

This S3 comes equipped with Shimano's Ultegra precise and instantaneous electronic shifting to ensure no valuable time is wasted when pushing for the line!

  • The full carbon frame is optimised to minimise drag and maximise speed without compromising comfort.
  • Dropped Down Tube - minimising the gap between the down tube and the front wheel helps minimise drag.
  • The airfoil-like curved seat tube shields the rear wheel.
  • Cervélo's Reduced-Friction BB Guide ensure your gear cables enjoy an easy run.
  • Future-Proof Cable Management makes the Cervélo S3 ready for a future Di2 upgrade.
  • Ultegra has a great track record for being the reliable first choice of more and more getting-serious road bike riders.

Here's How Cervélo Describe the S3 Disc Ultegra Di2


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.


Each Cervélo bike combines select Design Features- technologies created by our engineers to further the performance of the bike across five key attributes: aerodynamics, weight, stiffness, ride quality, and usability. All are engineered to make the one difference that matters: a difference you can feel.
