Product Information

Cervélo S3 Disc Ultegra Di2 Road Bike

The all-new S3 disc, in its second edition, takes the aerodynamic advantages from the S5 and provides it at a reduced price so you can get excited about riding it in the bunched sprint, local criterium or with your mates on a new year's Sunday morning ride. The S3 features revised tube shapes benefiting from Cervélo's TrueAero technology that not only reduces overall wind resistance but also reduces rider fatigue and discomfort by soaking up the road shatter provided by Britain's finest roads?! The front end of the S3 has also been changed with a brand new stem and handlebar that is sleeker and more comfortable, perfect for long days in the saddle. A DT Swiss disc wheelset ensures you have the wheels you need for rugged lightweight durability whilst on high mileage training rides or getting you to your next cafe stop! Finally, in this edition of the S3, you will find Shimano's Ultegra hydraulic disc di2 groupset is used to improve braking efficiency in the wet and provide electronic shifting that is smooth even when under intense power. 

Full Specification



More Aero

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.


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.
