Cervelo S5 Ultegra 8020 Disc Road Bike

Ride fast and ride in complete comfort on the Cervelo S5 Ultegra 8020 Disc Road Bike, completely redesigned to provide top aerodynamics and a stiff and power-efficient ride, with no compromise on comfort. The frameset's material, layup and shape offer a stable and predictable ride with head tube and bottom brackets stiffness being increased by 13% and 25% respectively.

The bike has been built up with Shimano's reliable and high-performance Ultegra hydraulic disc brake groupset, for smooth and precise shifting and powerful yet modulated braking in both wet and dry conditions. The DT Swiss P1800 Spline 32 Disc wheelset is a great all-rounder, just as capable on the climbs as it is on the flats.

Bike Fit

The Cervelo S5 is designed to fit the rider with absolute precision and must be set up by a certified Cervelo dealer. Please contact our Sales Team before making a purchase. For online purchases, our sales team will require a fit report from a certified bike fitter, detailing your optimal saddle height, reach and handlebar drop. This will help us to ensure the bike is set up correctly for you. If you do not have this information, you're most welcome to visit one of our stores or book a bike fit with us on our Bike Fitting page.
