Cervelo S5 Road Frameset Five Black 2, 51cm

What Our Gearhead(R) 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.
