Cervelo's S5 Ultegra Di2 8070 Disc Road Bike pairs their latest aerodynamic frame with Shimano’s excellent 11-speed electronic groupset for a machine that is incredibly fast through the air and a joy to ride quickly.

The unique stem and handlebar set up is stiff, adjustable and very low drag, whilst the DT Swiss ARC 1450 disc wheelset is a great match for the frame with the 62mm deep rims providing a high speed, low drag ride.

Cervelo S5 Ultegra Di2 8070 Disc Road Bike 2020

The Cervelo S5 Ultegra Di2 8070 Disc Road Bike is stiffer, more aerodynamic and handles better than its race-winning predecessor. The bottom bracket is 25% stiffer and the headtube 13% stiffer so that more power is transferred to the tarmac and the steering is even more precise. The TrueAero carbon frame has features such as fully internal cabling and extended seat tube cut out that wraps the tube around the rear wheel in its quest for less drag, whilst the striking front end is also highly aerodynamic with the stiff V-Aero stem presenting a low profile to the wind. Comfort is taken care of by the 28mm tyre clearance and carbon layup that adds compliance where it is needed most.

Shimano’s 11-speed Ultegra Di2 8070 groupset brings fingertip control of both gear selection and brakes, with the electronic shifting quick and precise, and the hydraulic braking confidence-inspiring in all weathers. In keeping with the pace of the bike, the DT Swiss ARC 1450 62 Disc wheelset has also been designed for maximum speed, with the 62mm deep carbon rim able to cut through the air and add to the bike’s peloton-leading credentials.

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 store or book a bike fit with us on our Bike Fitting page.
