The Cervélo R5 is built for riders who demand the ultimate climbing machine, one that’s not only feather-light but also strong enough to take on the world’s steepest and most punishing climbs. At just 5.97kg in RED and Dura-Ace builds, the new R5 is nearly a kilo under the UCI weight limit, pairing an ultra-light 651g frame with a refined 298g fork. Every detail has been obsessed over, from the all-new HB18 bar/stem that drops weight and adds aero efficiency, to the Reserve 34|37 SL wheels engineered for strength without compromise. Inspired by the victories of Wout van Aert and Pauline Ferrand-Prevot, this is the bike that shines on long climbs, accelerates with authority, and descends with complete confidence. With updated geometry to mirror the race-proven S5, a perfectly dialed fit with 15 cockpit size options, and weight savings across every component, the R5 continues its legendary status as the purest expression of a mountain stage race bike.
