The R5 tips the scales at just 5.97 kg / 13.16 lbs in a size 56, making it one of the lightest road bikes Cervélo has ever built. Every detail was reconsidered—the frame, fork, cockpit, and small parts were trimmed down, saving hundreds of grams while maintaining stiffness. Its updated tube profiles use a more defined blend and squared-off tail, smoothing airflow while reducing surface area for added efficiency. The result is a bike that accelerates instantly uphill, descends with composure, and retains the clean, classic look the R5 is known for.

The R5 now mirrors the geometry of Cervélo’s fastest race bike, the S5, with a longer reach and lower stack. This puts riders in a position that’s efficient on climbs and balanced on descents, while still comfortable enough for long days in the saddle. The top tube has been rotated up to boost stiffness in the rear end, bringing the frame more in tune with the S5. A slightly lower bottom bracket accommodates larger modern tires, improving aerodynamics, traction, and rolling efficiency. It’s a fit that doesn’t just look pro—it rides that way too.

The new HB18 one-piece handlebar and stem is lighter, stiffer, and more aerodynamic than its predecessor. Shaped with input from the S5, it now features narrower hoods and a modernized drop for improved comfort and control. At speed, it feels more stable, while multiple width and length options make it easier than ever to dial in your perfect fit. Every bar size remains fully UCI-legal under the latest rule changes.

The Reserve 34|37 SL wheelset trims 60g from the build, but its real strength is balance. Designed specifically for the new R5, the 34mm front delivers agility and control on technical climbs, while the 37mm rear keeps the bike planted and efficient at speed. Together, they create a ride that feels fast, stable, and composed across every road. These wheels make the R5 a complete package for riders who want confidence on both sides of the mountain.
