The R5 is a legendary bike. From the mythical R5CA, capable of breaking every limit, to Wout van Aert’s historic victory on Mont Ventoux, this bike has been an integral part of Cervélo’s history for over twenty years.
The new R5 is an incredibly lightweight road bike — under 6 kg in RED and Dura-Ace builds — yet stiff enough to compete at the highest level of modern professional cycling, as demonstrated by Pauline Ferrand-Prévot when she rode it to victory at this summer’s Tour de France Femmes.
Nowadays, building a lightweight bike is relatively easy. The real challenge is creating one that combines lightness with the stiffness required to transfer all the power of the sport’s top champions to the road.
Designed for the great mountain stages of the Tour de France and for the steep, demanding climbs of the Vuelta a España, the R5 excels both uphill and downhill. A bike built for climbing must accelerate instantly, climb efficiently, and also deliver confidence and predictability on descents.
Although the UCI imposes a minimum weight limit of 6.8 kg for Pro races, we “mere mortals” can benefit the most from having the lightest road bike on the market.
CERVELO R5 ULTEGRA BIKE – KEY FEATURES:
- Only 5.97 kg in size 56: The new R5 in size 56 weighs just 5.97 kg, a full 900 grams below the UCI minimum weight limit. The frame alone weighs 651 grams (size 56) and the fork 298 grams. In addition to a 100 g reduction in frame and fork weight, attention was paid to every single component, resulting in a total weight saving of 326 g across all Cervélo proprietary components.
- Race-ready geometry: In terms of handling and ride quality, the geometry of the new R5 remains virtually unchanged, aside from a slight adjustment to the BB drop that allows for tires up to 29 mm. The fit, however, has been updated to mirror that of the S5. This means that if you switch between models, as Team Visma | Lease a Bike does, you’ll always maintain the same position and riding feel. If the R5 is your only bike, you can count on a modern, performance-oriented riding position.
- One-piece handlebar: The brand-new R5 one-piece integrated HB18 handlebar not only reduces the bike’s weight by nearly 150 grams, but also improves aerodynamics by 2 watts compared to the previous model. Drawing on knowledge gained from the S5 handlebar, we developed a bar that is comfortable, fast, and stiff—ideal for long days in the saddle and hard-fought finishes. All handlebar dimensions comply with UCI regulations, including the most recent rule updates.
- Ultralight Reserve 34 | 37 SL wheels: Designed specifically for the R5, the new Reserve 34|37 SL wheelset allowed us to save an additional 60 grams. The new wheels deliver the same strength and stiffness as before, thanks to a revised structure that reduces weight without compromising performance.
- The one-piece handlebar and stem of the new R5 have played a key role in reducing overall weight, but we also know that a perfect fit is essential to get the most out of your new bike. That’s why we offer 15 different size combinations, and when you purchase an R5, your authorized Cervélo dealer will help you find the right setup at no extra cost.
