Description

The new 2026 Cervelo R5 is an incredibly light road bike that’s also stiff enough to compete at the highest levels of professional cycling, as Pauline Ferrand-Prevot proved when she rode it to victory at this summer’s Tour de France Femmes.

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.

Only 5.97kg in RED and Dura-Ace builds, a full 900 grams under the UCI’s minimum weight limit.
