Cervelo S-Series Ultegra Disc Road Bike 2021
A versatile character that is realised thanks to a sophisticated design and an advanced construction enables the Cervelo S-Series Ultegra Disc Road Bike to perform more than admirably up climbs, through the valleys and when sprinting for the line.
The aerodynamically chiselled tube profiles of the S3’s frameset lower drag significantly and these are realised in a high-grade of carbon fibre that infuses reactivity, efficiency and assured handling characteristics into the ride while keeping the weight low. Hidden gear cable and brake hose routing that runs through the stem and into the frame further lowers the drag and also creates a crisp aesthetic.
DT Swiss P1800 32 Spine wheels are nimble but robust thanks to their lightweight but sturdy alloy rims. Gear changes are courtesy of the super-reliable and accurate Shimano Ultegra 11-speed drivetrain and composed, but powerful braking under any weather conditions is donated by the matching Ultegra hydraulic disc configuration.
