Cervelo S5 Dura-Ace Di2 attacks with a lighter, faster aero frame
The Cervelo S5 Dura-Ace Di2 is an aero road bike built around a reworked frame that trims drag and weight from the previous S5, with the largest gains concentrated at the fork and head tube. A new one-piece bar and stem tightens the front end further, cutting bulk without adding complexity to fit. Cervelo co-developed the Reserve wheelset specifically for this frame, so the wheels and tube shapes work as one aerodynamic system rather than two separately optimized parts.
What Our Gearhead® Experts Are Saying:
"Coming into a sprint finish with my legs cooked, the Dura-Ace Di2 shifters still fire exactly when I ask them to. Every gear lands clean even when I'm too tired to feather a shift the way I could an hour earlier."
Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead® Experts are always here to help.
