Product Information

Cervélo S3 Rim Ultegra Di2 Road Bike

The S3, the younger sibling to the powerhouse S5, takes many of the technologies used to design the S5 and offers its services at a reduced price. Cervélo designed the S3 for those looking to speed their way through criteriums and bunch sprints as well as provide enough comfort for your Sunday morning group spin. The revised design on the S3 uses a new handlebar and stem combination which helps to enhance comfort by soaking up road shatter as well as being more efficient in its shape against the wind. The TrueAero tube shapes are a new feature on the S3 helping to reduce rider muscle fatigue through a smoother, more constant ride as well as stabilising your geometry and further improving overall stiffness, so when the power goes in ... speed comes out. Finally, this set up of the S3 has been finished with Shimano's Ultegra Di2 8050, allowing you to switch between gears swiftly and soundly, providing you with maximum comfort whilst out riding this head-turning new bike from Cervélo!

Full Specification



More Aero

If you want more speed, you need to look at your aerodynamics. For the new S3 hours were spent in the wind tunnel, testing and refining designs until the very best combination was found: Full internal cable routing, a new bar and stem, and frame shapes work together to reduce drag on you and the bike, allowing you to go faster.


Optimised Stiffness

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. 


Faster for all

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.


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 S3 so you can reap the benefits of reduced drag.
