Product Description
2026 Cervélo S5 SRAM RED AXS
Speed Reimagined. 6 Watts Faster. Zero Compromise.
The 2026 Cervélo S5 SRAM RED AXS Carbon is the absolute pinnacle of aerodynamic road racing engineering, built to give sprinters and breakaway specialists an uncompromised competitive edge. Crafted around Cervélo's relentless TrueAero carbon frame with an integrated Bayonet fork, this flagship superbike minimizes wind resistance while delivering immense bottom-bracket stiffness for explosive out-of-the-saddle efforts. Outfitted with SRAM's featherweight 12-speed RED AXS E1 wireless electronic drivetrain, an integrated dual-sided power meter, ceramic bottom bracket, ultra-fast Reserve 57/64 Turbulent Aero carbon wheels on DT Swiss 180 hubs, and the revolutionary HB19 one-piece V-cockpit, it provides an aggressively tuned, wind-tunnel-proven platform engineered to transform raw power into record-breaking speeds.
Elite Aerodynamic & Performance Features
TrueAero Carbon Frame: Utilizes deeper chord profiles along the fork and head tube, precisely sculpted to minimize aerodynamic drag even during high yaw crosswind conditions.
SRAM RED AXS Drivetrain: The lightest 12-speed wireless electronic groupset available, featuring an integrated power meter and ultra-efficient ceramic bearings for maximum mechanical efficiency.
HB19 Carbon One-Piece Cockpit: The iconic V-stem evolved into a seamless single-piece system with a "Plus-Four" flared design, creating a 4cm narrower hood stance for an ultra-efficient aero position.
Reserve 57/64 Aero Wheelset: Custom-tuned to match the S5 frame profiles and paired with DT Swiss 180 hubs, delivering exceptional crosswind stability along with a 3-watt performance advantage.
Asymmetric Frame Integration: Features a sculpted seat tube that closely contours the rear wheel, smoothing airflow across the rear wheel section to ensure maximum forward momentum.

Built for the Finish Line
The Cervélo S5 remains the world's most dominant aero bike for a reason. By refining the iconic V-stem into the HB19 one-piece cockpit and widening tire clearance to accommodate the high-volume Vittoria Corsa Pro 29mm tires, Cervélo has delivered a ride that is not only faster but significantly more comfortable. Whether you are sprinting for a World Tour podium or hunting a local KOM, the S5 offers the stability and razor-sharp responsiveness needed to perform under pressure.
