Description
The S5 Ultegra Di2 Disc Road Bike is based around Cervelo’s multiple Grand Tour winning frame, with Shimano’s latest 12-speed Ultegra groupset and top-drawer finishing kit.
TrueAero frame design ensures that the tube shapes are all highly aerodynamic and efficient at transferring the power whilst features such as the seat tube cutout shield the rear wheel from the wind and the narrow head tube profile reduces drag. The distinctive V-shaped stem also helps the bike cut through the wind yet maintains the necessary handlebar stiffness needed for confident control.
Carbon Reserve 50 wheels with disc DT Swiss 350 hubs offer excellent handling and can be easily set up tubeless with the Vittoria Corsa TLR G tyres. Should more comfort be required, then the frame and fork have sufficient clearance for 28mm rubber.
Now with 12-speed gearing, Shimano’s superb Ultegra Di2 drivetrain is incredibly accurate and quick across the cassette or chainrings, with the extra sprocket meaning smaller jumps between gears so that the perfect cadence is easier to find.

Riding a bike that fits you perfectly will help keep you injury-free and ensure you enjoy riding further for longer in total comfort. We check your measurements on a jig to ensure your optimal set-up.
