Cervelo R5 Dura-Ace Di2 2026 - Road Bike

The R5 Dura-Ace Di2 is the ultimate expression of lightweight performance, engineered for riders who demand total efficiency on the toughest climbs. Built around an ultra-refined carbon frameset weighing just 651g, the complete bike tips the scales at an astonishing 5.97kg, making it one of the lightest production road bikes available.

This premium build features Shimano’s flagship Dura-Ace Di2 12-speed electronic groupset, delivering lightning-fast, accurate shifting in all conditions. A 4iiii dual-sided power meter provides detailed performance data, while Reserve 34/37 SL carbon wheels paired with DT Swiss hubs offer outstanding responsiveness and stability.

Cervélo’s integrated HB18 carbon cockpit enhances aerodynamics while reducing weight, and high-performance finishing components—including a CeramicSpeed bottom bracket and Vittoria Corsa Pro tyres—ensure a smooth, efficient ride. With clearance for wider tyres, the R5 also brings added versatility and comfort to long days in the saddle.

Blending legendary heritage with cutting-edge engineering, the R5 Dura-Ace Di2 is built for one purpose: to reach the summit first.

It’s easy enough to make a light bike, but to make a light bike that’s stiff enough to accelerate quickly and transfer power from the sport’s biggest motors? That’s another challenge entirely. R5 is the bike for big days in the high mountains of the Tour de France, and the punishingly steep climbs of the Vuelta a Espana. Bikes built for the mountains must not only accelerate rapidly and climb exceptionally, but descend confidently and predictably. While the UCI mandates a minimum weight of 6.8kg, those of us in the ‘mere mortal’ category will benefit from having the lightest road bike on the market.
