Cervelo S5 Ultegra Di2 2026 Road Bike

Pure Speed, Refined

The Cervélo S5 Ultegra Di2 is engineered for sheer aerodynamic dominance—faster, lighter, and more efficient than ever. A proven race weapon, it’s the bike of choice for champions like Wout van Aert and Simon Yates, with wins in the world’s biggest races. Built around the iconic V-stem and bayonet fork, the all-new S5 brings serious aerodynamic gains, weighing in 124 grams lighter and delivering a 6.3-Watt performance boost over its predecessor.

At the heart of the performance gains is a redesigned front end with deeper fork legs and head tube, plus a one-piece HB19 handlebar/stem with a narrow-hood “Plus-Four” shape for a more aero riding position. Paired with Reserve 57|64 Turbulent Aero wheels—designed in tandem with the S5 frame—airflow is optimised across every surface, delivering unmatched speed and crosswind stability.

Equipped with Shimano’s 12-speed Ultegra Di2 electronic drivetrain and a dual-sided 4iiii power meter, the S5 offers precise shifts and real-time data tracking. Every component is tuned for performance—from DT Swiss 240 hubs and Vittoria Corsa Pro tyres, to a carbon seatpost and Selle Italia NOVUS saddle.

Key Features:

• Aerodynamic upgrade: 6.3 Watts faster than previous S5
• Lighter build: 124g reduction despite increased surface area
• Reserve 57|64 Aero wheels: Designed to match frame profile
• Ultegra Di2 12-speed groupset: Smooth, accurate shifting
• Integrated HB19 cockpit: Aero-focused with narrow hoods
• Dual-sided power meter: 4iiii Precision Pro GEN3+
• 29c Vittoria tyres: Tubeless-ready speed and grip

For the rider chasing every Watt, every gain, and every podium—this is the aero road bike that leads from the front.
