Product Information

Cervélo S3 Disc Ultegra Road Bike

The Cervélo S3 surprised us when it first came out as it quickly established itself as our best-selling Cervélo road bike. Lots of riders found the S3 the perfect combination of comfort and speed, the blend of aero tube shapes with R-series rear stays hit the sweetspot for a wide variety of road cyclists.

The new Cervélo S3 Disc Ultegra comes with a new bar and stem combination which hides the cables and no doubt gives an extra aero advantage. Couple this with updated aero tubing, improved stiffness in the bottom bracket area and headtube and Cervélo (and us) have another winner on their hands.

The Cervélo S3 Disc Ultegra has a full Shimano Ultegra 8020 disc groupset allied to DT Swiss Spline wheels and give you a bike that's ready to tackle training, racing, sportives or triathlons with no upgrades necessary.

FEATURES

TECHNOLOGIES

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.
