Description
Cervelo S5 Ultegra Di2 Road Race Bike
The Cervelo S5 Ultegra Di2 is built for pure speed. It is one of the fastest road race bikes in the world, proven at the front of the professional peloton. The latest S5 is even faster, lighter and more aerodynamic, while keeping the stable handling and race feel riders expect. It has helped riders win major jerseys, take stage victories and lead Grand Tours.
The new S5 is over 6 Watts faster than the previous model and 124 grams lighter. Most gains come from the deeper fork legs, reshaped head tube and the new one-piece carbon handlebar and stem. The cockpit uses Cervelo’s Plus-Four concept, with a narrower hood position for better aerodynamics and wider drops for stability when sprinting or descending. All sizes are UCI legal.
Cervelo and Reserve developed the Reserve 57|64 wheelset specifically for the S5. The rear wheel’s asymmetric profile matches the seat tube to improve airflow. The wheels are 3 Watts faster than the previous 52|63 set and weigh the same. The S5 is a complete aerodynamic system built for racing at the highest level.
This build pairs the aerodynamic frame with Shimano Ultegra Di2 12 speed electronic shifting, a power meter and the Reserve 57|64TA wheelset with DT Swiss 240 hubs. It is a fast, efficient and highly capable race bike ready for top-level road racing.

Aero Aero Aero
The S5 is designed as a complete aerodynamic system. The deeper fork legs, reshaped head tube and integrated cockpit deliver major drag reductions. The seat tube and rear wheel profiles work together to smooth airflow.
Lighter And Faster
Despite the deeper front end, the new S5 is 124 grams lighter. Cervelo optimised the carbon layup and hardware to reduce weight without losing stiffness or stability.
One-Piece Carbon Cockpit
The HB19 bar uses the Plus-Four concept. The hoods are 4 cm narrower than the drops. This improves aerodynamics on the hoods and stability in the drops. All sizes meet UCI rules.
Reserve 57|64TA Wheels
The Reserve 57|64TA wheelset was co-developed for the S5. The asymmetric rear wheel matches the seat tube shape. The wheels are 3 Watts faster than the previous 52|63 set and weigh the same. DT Swiss 240 hubs add reliable performance and quick engagement.
Shimano Ultegra Di2 Drivetrain
Ultegra Di2 provides smooth, precise electronic shifting with a wide 11 to 34 tooth cassette. The 52/36T chainrings and power meter add efficiency and accurate training data.
