Cervelo S5 Dura-Ace Di2

About This Bike

The Cervélo S5 Dura-Ace Di2 represents the benchmark for aerodynamic road performance. Refined through years at the front of the WorldTour peloton, the S5 pairs Cervélo’s signature V-stem and bayonet fork with a deeper, more aerodynamic front end to deliver measurable gains where it matters most. Over 6 watts faster and significantly lighter than its predecessor, the latest S5 is engineered as a complete aerodynamic system. The Reserve 57/64 Turbulent Aero wheelset was co-developed specifically for this frame, working in conjunction with the asymmetric seat tube to maintain smooth airflow and stability, even in crosswinds. The one-piece HB19 carbon cockpit further enhances integration and speed, using Cervélo’s Plus-Four design to keep riders narrow and efficient on the hoods while maintaining control in the drops. This build is equipped with Shimano Dura-Ace Di2 12-speed electronic shifting, a dual-sided power meter, and a CeramicSpeed bottom bracket—delivering elite-level efficiency, precision, and performance with no compromises. From high-speed group rides to full-gas race scenarios, the S5 is built to do one thing better than anything else: go faster.
