A Heritage of Speed
The Cervélo R5 has been the benchmark for climbing excellence for over two decades. Whether it's proving its worth at the Tour de France Femmes or helping you conquer your local gradients, the R5 is built for the obsessed. By refining the fit geometry to match the aerodynamic S5, Cervélo has created a bike that feels as fast on the descents and flats as it does on the steepest peaks. With the HB18 carbon cockpit and refined tire clearance up to 34mm, this is the most capable and comfortable R5 ever built.
