Product ID: 1137230

Cervelo’s S5 Ultegra 8020 Disc Road Bike offers all the speed advantages of the rest of the S5 range but keeps the price down by using Shimano’s evergreen second-tier mechanical groupset.

The TrueAero carbon frame features a cutout to shield the rear wheel and is stiffer than the previous iteration by 13% at the head tube and 25% in the bottom bracket area whilst the V-shaped stem also adds stiffness and cuts drag.

Cervelo S5 Ultegra 8020 Disc Road Bike 2020

The Cervelo S5 Ultegra 8020 Disc Road Bike is Cervélo’s latest aerodynamically biased machine. The TrueAero design of the carbon frame improves airflow around the bike whilst also increasing stiffness in the areas that matter; around the bottom bracket and head tube. The V-shaped stem and handlebar provide all the advantages of a one-piece design but add flexibility as the stem and handlebar are actually separate and are fully adjustable so it's easier to find the optimal position for both aerodynamics and power output.

It may sit below their famed Dura-Ace groupset, but Shimano’s mechanical Ultegra components give nothing away in terms of performance, with the shifting across the 11-speed cassette being sharp and accurate. Race speed isn’t just about straight lines, and so the hydraulic disc brakes are a welcome addition, giving extra confidence to attack the bends even in wet conditions.

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.
