Cervelo S5 Ultegra Di2 Disc Road Bike 2023

Cervelo's S5 Ultegra Di2 Disc is their fastest, most aerodynamic road bike that has seen many pro-level victories.

The slippery carbon frame has been tweaked in line with the UCI’s slightly more relaxed regulations, with some deeper tube shapes and a reworked cockpit setup to reduce drag by a few more precious grams. This frame is now only compatible with electronic shifting and has sufficient tyre clearance for 34mm rubber within its sculpted shape. 

The instantly-recognisable aerodynamic V-Stem and handlebar arrangement is more adjustable and simpler now, with a small drop in weight into the bargain. Its lauded aerodynamic and handling advantages remain impressive and give the S5 an extremely purposeful-looking stance even when standing still.

Cervelo has taken advantage of its in-house Reserve wheel brand and developed a 63/52mm tubeless-ready carbon wheelset that integrates perfectly into the frame. This not only reduces drag when tested in the wind tunnel but also shows improvements when faced with real-world situations where the yaw angle is constantly changing, leading to more stable handling and added speed. 

Ultegra Di2 is Shimano’s second-tier, 12-speed, electronic groupset. It gives virtually nothing away to the range-topping Dura-Ace version in terms of performance and offers near-instant shifting and impressive braking control. The system is part wireless, which means that it can be connected to a GPS head unit or a smartphone via Bluetooth, giving access to more information during and after a ride as well as some function customisation.
