Cervelo S5 Road Frameset

Race-bred aerodynamics meet modern versatility in the S5 Road Frameset for all-out speed on open roads

What Our Gearhead® Experts Are Saying:

"I start with the S5 frameset any time the goal is outright speed. I’ve ridden aero frames that feel harsh or overly specialized, but this one balances stiffness, clean integration, and real-world tire clearance better than most. The front-end integration keeps the bike quiet and stable at high speeds, and it rewards strong efforts without feeling nervous when the road surface deteriorates."

We look to the S5 Road Frameset when speed is the priority and every watt matters. Cervelo built this platform for riders who want to push the pace in fast group rides, high-output training blocks, and race-day scenarios where aerodynamics make a measurable difference. From long, exposed straights to rolling terrain where momentum is everything, the S5 thrives when the pace stays high and the effort stays committed.

Cervelo pairs its aero carbon frame with a fully integrated cockpit and fork to create a front end that slices cleanly through the wind while staying composed under hard braking and sharp cornering. A stiffened head tube and BBRight bottom bracket maximize power transfer, while clearance for tires up to 34mm opens the door to wider rubber for rough pavement, endurance racing, and modern road setups that prioritize speed without sacrificing control.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.

The Cervélo Difference

Cervélo was founded in 1995 by engineers with a singular focus: measurable speed. From the start, the brand has taken an uncompromising, data-driven approach to bike design, defining clear performance goals, validating them through testing, and refining every detail until gains are proven.

This process has produced some of the most aerodynamically efficient, lightweight, and stiff bikes in the sport. Across road, aero road, triathlon, endurance, and track platforms, Cervélo continues to set benchmarks for performance and efficiency, trusted by professional teams and riders who demand results they can feel on the road.
