CerveloS5 Ultegra Di2 Road Bike

Speed redefined. The Cervelo S5 Ultegra Di2 Road Bike has evolved to be even more aerodynamic, slicing through the wind with refined front-end shaping and the sleek integration of asymmetric seat tube and rear wheel profiles. The result? A gain of 6.3 watts over its predecessor – extra power in reserve for launching a breakaway or delivering a decisive sprint finish. It’s not just quicker, it’s lighter too, shedding 124 grams for added efficiency when the gradient kicks up. While it’s faster and leaner, the S5 still delivers the precise handling, stability, and razor-sharp responsiveness that riders love. This is the S5, reimagined for those who love speed and ride on the edge.

Cervelo x Reserve 57/64 Turbulent Aero

Co-developed by Cervelo and Reserve, the57/64 Turbulent Aero wheelset has been tuned to work perfectly with this latest iteration of the S5 frame and forks. The asymmetry of the rear wheel matches the seat tube, ensuring smooth and efficient airflow over both. Meanwhile, the added depth of the front rim helps smooth airflow over the wheel in high yaw scenarios. Some 3 watts faster than its predecessor wheelset, the57/64 still tips the scales at the same weight.

Cervelo HB19 Carbon one-piece cockpit

The distinctive V-shaped bar and stem remain, but it’s now a one-piece setup. The“Plus-Four” concept gives a handlebar design where the width at the hoods is 4cm narrower than at the drops – for example, 38cm at the hoods and 42cm at the drops. This innovative setup promotes a more aerodynamic riding position when your hands are on the hoods, while still offering enhanced control and stability in the drops for sprinting and descending. All handlebar sizes comply fully with UCI regulations, including the most recent updates
