Built for smooth, uncompromising speed, the Cervelo S3 Ultegra Di2 Road Bike 2017 offers riders an Airfoil frameset, redesigned forks and the ultra-smooth electronic shifting of Shimano's Ultegra Di2 6870 system. On top of this comes a plethora of other superb features including the Fizik Antares VS and Mavic Cosmic Elite wheels.

Cervelo S3 Ultegra Di2 Road Bike 2017

The Cervelo S3 Ultegra Di2 Road Bike 2017 is yet another example of Cervelo's market leading dedication to aerodynamics, a fact testified to by their record at the Ironman World Championships. This dedication to wind tunnel research and testing has allowed them to produce this bike that cuts through the wind like never before. Airfoil sections help with this, as does the minimalist rear triangle that has been borrowed from the top of the range RCA frameset. These thin stays offer comfort and minimise road buzz.

Completing this phenomenal bike is Shimano's fantastic Ultegra Di2 6870 groupset with Rotor 3D30 BBright™ crankset. This provides you with silky smooth and reliable 11-speed shifting, as well as the easy option to upgrade to Q rings should you feel the need to get more out of your pedal stroke for a triathlon, race or just to improve your recreational riding. Should you be looking to upgrade, the future proof design allows for internal electronic, mechanical, or hydraulic shifting and braking lines.

Comfort has not been forfeited for speed and the new frame features greater tyre clearance than ever before, allowing you to fit 25 millimetre wide tyres on to the aerodynamic and reliable Mavic Cosmic Elite rims, that have also been redesigned for this year.


  • Now with BBright for optimal stiffness to weight ratio

  • Boosted torsional (+23% vs last generation S3) and bottom bracket (+16%) stiffness for agile, responsive handling and efficient power transfer on the attack

  • Future-proof cable routing

  • Lightweight, interchangeable ICS (internal cable stops) click into the frame to fit mechanical, electronic or hydraulic lines

  • Sleek, smooth and mechanic friendly

  • Downtube shape is designed for stiffness

  • New fork for improved lateral stiffness, better tracking and handling, and larger tyre clearance

  • Partial seat tube cutout improves airflow around rear wheel, while allowing for larger tyre clearance
