2027 Cervelo S5 Red AXS - Five Black

The all-new 2027 Cervélo S5 Red AXS sets a new benchmark in aerodynamic road bikes. Engineered for ultimate speed, stiffness, and ride quality, this race-proven machine is now lighter, faster, and more refined than ever before.

Designed with insight from World Tour professionals and the latest computational fluid dynamics (CFD), the 2027 S5 outpaces its predecessor with next-gen aerodynamics, improved compliance, and smarter integration.

2027 Cervélo S5 Features

• Enhanced Aerodynamics: Refined tube shapes reduce drag by an additional 8.7 watts at 40km/h compared to the previous S5.
• Lighter Frame: The 2027 S5 sheds 124g without compromising stiffness thanks to advanced carbon layup and improved design.
• State-0f-the-Art Aero Cockpit: V-stem and integrated bars improve airflow and reduce frontal area for superior wind slicing, saving 1 watt.
• Refined Ride Quality: Reworked seat stays and updated geometry enhance compliance, offering better comfort on long, punishing rides.
• Cable Routing: Fully internal cabling improves aesthetics and aerodynamics, with easier access for maintenance.
• Reserve 57/64 Wheelset: 10% stiffer. 3 watts faster. Faster aerodynamics with the same weight as the previous 52/63’s.
• SP34 Seatpost: The SP34 seatpost saves 27g compared to the previous generation, and provides increased fore-and-aft adjustment while maintaining excellent stiffness.
• Updated Cable Routing: Fully internal cabling improves aesthetics and aerodynamics, with easier access for maintenance.
• Now Available in Size 61cm: The 2027 S5 range expands to include a 61cm frame, making Cervélo’s flagship aero bike accessible to taller riders.
