  • Go Faster

    The S-Series makes every part of your ride better: the final sprint on your Saturday morning group ride, the long climb, and a solo effort on the edge of town. We've applied years of experience of building the most aero bikes in the peloton to create a bike that delivers maximum performance.

    Ideal For: Group rides / Solo efforts

    Cervelo - S-Series - 2021
  • Aerodynamics - Trusted aerodynamics

    The S-Series is designed to be an aerodynamic integrated system incorporating the rider, frame, and components. Frame tube shapes and design elements work together to manipulate and smooth the airflow over the bike and rider. The result: you go faster.

    Stiffness - Optimized performance

    Stiffness in critical parts of the frame is essential for calm and precise handling and pedaling efficiency. Most aerodynamic bikes have to trade off aerodynamics for stiffness, but we worked hard to ensure the S-Series frames are stiff, while not sacrificing aerodynamic performance.

    Usability - Built for you

    Cervélo builds bikes that are easy to own - so you can spend less time servicing them and more time enjoying the ride. The S-Series is specced with components that are easy to upgrade, and the bike is designed to be ready for electronic, mechanical, or hydraulic shifting.


    Partial Seat Tube Cutout

    Our Partial Seat Tube Cutout is a shorter version of our Extended Seat Tube Cutout, providing improved aerodynamic performance at a lower cost and with a different look.


    Cervélo developed BBright™ to take advantage of the fact that oversized frame tubes are stiffer and lighter. With the BBright™  system, larger-sized tubes are used in the seat tube, down tube, and lefthand chain stay. The benefit is increased stiffness and pedalling efficiency in a lighter weight frame. BBright™  is compatible with all major bottom bracket standards.

  • All bikes purchased from iRIDE will have been pre-assembled by our mechanics and test ridden. You will also receive a multi point checklist of all the safety checks and bike build elements we work through to ensure you bike is correctly assembled, and then tested so that it runs as it should. Bikes being sent to a customer who is unable to collect it from iRIDE, will have it boxed, wheels, saddle and bars generally off and re-packaged.

    The delivery of bikes will be organized once a freight fee can be determined based on weight and delivery location.

    Assembly should take no longer than 10-20 minutes. It is recommended that a skilled mechanic assemble, or check the bike. If possible your local bike shop is likely best placed to do this from a safety perspective to ensure all is as it should be. If a rider is having any issues we can hook up an online video chat, or talk over the phone. If this service is required email us at to organise a time that suits all parties.
