R5

The R5 is Cervelo's classic climber, descended from the R-series that Carlos Sastre rode to victory in the 2008 Tour de France. The latest generation unveiled mid-2025 was first spotted under Matteo Jorgenson at Visma-Lease a Bike's team hotel and made the obsession with weight loss its headline: complete builds in size 56 come in at 5.97 kg, well under the UCI's 6.8 kg minimum. The new HB18 integrated bar/stem shaved nearly 150 g while making the bike claimed to be 2 W more aerodynamic than the predecessor, and the matching Reserve 34/37 SL wheelset trimmed another 60 g. Pauline Ferrand-Prevot raced the 2025 Tour de France Femmes on it. It is now positioned as the lightest production road bike in the World Tour peloton.
