Cervelo S5 Dura-Ace Di2 Disc Road Bike 2023

Judged by professional racing results, Cervelo's S5 Dura-Ace Di2 Disc Road Bike must be one of the most successful bikes ever made. 

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.

Sitting proudly atop Shimano’s road groupset range, Dura-Ace Di2 offers effortless 12-speed semi-wireless shifting and consistent, powerful hydraulic braking. The system can be paired via Bluetooth with a GPS head unit or smartphone for access to ride data and battery information whilst Shimano’s app also allows for some customisation and automation of shifting functions. The hydraulic disc brakes use Servo Wave technology from Shimano's mountain bike line so that the pads have more clearance to the rotor and there is improved power and modulation. 

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.
