Cervelo S3 Ultegra 8020 Disc Road Bike 2020

A high-performance disc brake build, the Cervelo S3 Ultegra 8020 Road Bike is stiff, light and compliant, and supplied with a race-ready spec. Engineered for speed, you'll get the edge over your competition thanks to the TrueAero frame design. When it comes to sprinting for the line, chasing down breaks or any other situation where you need rapid acceleration, you'll appreciate the increased stiffness in the bottom bracket, efficiently transferring all your power.

This frame offers stable and precise handling, and has been specced with a Shimano Ultegra mechanical groupset for smooth, reliable, fast shifting, and powerful disc braking. The DT Swiss wheels are a great all-round set, rolling fast and smooth on Continental GP SL 25mm tyres.


  • TrueAero combines specific tube shapes, sizes and design features to improve aerodynamic flow
  • BBright system - Utilising larger tubes in the seat tube, down tube and left-hand chainstay, stiffness and pedalling efficiency are increased while keeping weight to a minimum
  • Aero Cable Management - The fork, frame and handlebar hide the brake and gear cables from the wind for improved aerodynamics, with no compromise on performance
  • Shimano's Ultegra groupset is performance-oriented yet retains durability and reliability
  • Shimano Ultegra hydraulic disc brakes
