The Cervélo S5 represents the pinnacle of aerodynamic road bike design, a machine purpose-built for racing at the highest level with victories to prove its pedigree. With its iconic V-stem and bayonet fork design, the S5 is synonymous with speed, and in its latest iteration, Cervélo has taken that winning formula and made it even faster, lighter, and more refined. The newest S5 shaves more than 6 watts off its previous model's drag while trimming 124 grams from its total weight, reinforcing its status as the benchmark aero road bike. The aerodynamic improvements stem largely from a completely reimagined front end. Deeper fork legs and an enlarged head tube channel air more efficiently, working in concert with the redesigned one-piece V-stem handlebar to further reduce turbulence. The new HB19 handlebar uses Cervélo's "Plus-Four" concept, offering a 4cm narrower grip at the hoods than the drops to help riders achieve a more aerodynamic position while maintaining descending and sprinting control. Even with more surface area, this new front-end setup contributes to the overall weight savings thanks to layup and hardware optimization throughout the frame.

Cervélo’s engineering team partnered with Reserve to co-develop the new 57|64 Turbulent Aero wheels specifically for the S5. These wheels are more than just deep and fast—they’re designed to work harmoniously with the asymmetric seat tube cutout of the S5, ensuring clean, uninterrupted airflow across the bike. With a rear wheel profile shaped to match the unique asymmetry of the frame, the Reserve 57|64 setup is not only more aerodynamically efficient but also remarkably stable in crosswinds, improving rider confidence on fast, technical courses. Testing reveals these wheels are 3 watts faster than the previous 52|63 setup, without any weight penalty.

The S5 doesn’t simply chase numbers—it’s engineered for real-world racing and rider feel. Its geometry, handling, and poise remain intact, offering the stability and agility that elite cyclists demand. The aerodynamic benefits are balanced with a ride quality that excels not just in straight-line speed, but also in cornering precision and descending control. The one-piece HB19 bar/stem system provides both aerodynamic savings and unmatched cockpit integration, resulting in a clean, race-ready front end that supports both performance and ergonomics.

Cervélo’s dedication to continuous improvement means every update to the S5 serves a purpose. From the integrated handlebar to the co-developed wheelset, every element of the bike has been designed to work in harmony for maximum performance. It’s not just about cutting drag—Cervélo has ensured that each watt saved translates to greater speed on the road, whether you're sprinting to the finish line or slicing through a windy mountain descent.

This attention to detail and performance-first design philosophy continues to set the S5 apart from its competitors. By pushing the envelope of integration and aero optimization, Cervélo has created a race bike that is not only faster but more complete. The new S5 is engineered to dominate the pro peloton and deliver podium-worthy speed to dedicated riders everywhere. Whether it’s winning grand tours or chasing PRs, the S5 is the choice for riders who demand the best in speed, stability, and innovation.
