The Cervlo S5 has established itself as a benchmark in aerodynamic road racing, proven by victories from riders like Jonas Vingegaard and Wout van Aert at the highest levels of the sport. The latest generation builds on this success by improving aerodynamic efficiency by over 6 watts compared to the previous version and reducing overall weight by 124 grams. The front end of the frame sees the most significant changes, with deeper fork legs and a refined head tube profile that contribute to smoother airflow and increased speed. The S5s updated one-piece HB19 handlebar and stem use the Plus-Four design, positioning the hoods 4 centimeters narrower than the drops to encourage a more aerodynamic body position while preserving stability during sprints and descents.

The Reserve 57|64 wheelset was co-developed with Reserve specifically for the new S5. This setup features asymmetric profiles that match the seat tube shape, allowing air to move cleanly across the frame and wheels as a cohesive system. The wheels deliver a 3-watt improvement over the previous Reserve 52|63 model without adding weight. Cervlo also optimized the carbon layup and hardware throughout the frameset to balance the increased surface area with lower mass, improving acceleration and responsiveness. The newest iteration of the S5 makes speed come easier without sacrificing handling.

Each S5 includes nine available bar and stem size combinations to help riders achieve a precise fit without compromising aerodynamic performance. The new design remains fully UCI-legal and integrates easily with modern cockpit accessories. This version is equipped with a SRAM Red XPLR AXS groupset for elite 1×13-speed electronic shifting that can take on more difficult roads. It also comes with a Hammerhead Karoo computer and a power meter, making it a complete tour-level setup. The Cervlo S5 combines proven race pedigree, refined aerodynamics, and lightweight construction, making it one of the fastest bikes on the planet.
