The Cerve;lo R5 is legendary for good reason. This all-new edition continues a storied heritage dating back over two decades, recently proven on cycling&';s biggest stages by Pauline Ferrand-Prevot&';s victory at the Tour de France Femmes. The R5 isn&';t just another lightweight road bike; it&';s a race-winning machine that proves you can achieve both extreme lightness and the stiffness required to compete at the highest levels of professional cycling. At just 5.97kg in a size 56, the R5 sits a full 900 grams under the UCI&';s minimum weight limit, making it the lightest road bike on the market. This featherweight construction doesn&';t come from cutting corners, it comes from Cerve;lo&';s relentless refinement of every component. The carbon frame weighs just 651 grams while the fork is a mere 298 grams, combining for a frameset that delivers the responsiveness and acceleration demands of elite cycling without the weight penalty. The all-new HB18 one-piece handlebar and stem represents a watershed moment in cockpit integration, shaving nearly 150 grams compared to previous generations while also making the bike two watts more aerodynamic. Developed from insights gained on the S5, the HB18 provides the comfort and stiffness needed for sustained efforts and sprint finishes, with every bar size remaining UCI-legal even under the most recent regulations. What truly sets the R5 apart is how Cerve;lo has achieved this weight reduction without sacrificing the handling precision and power transfer expected of a world-class climber&';s bike. The fit geometry now matches the S5, positioning you stronger for fast group rides whether you&';re switching between models or committing fully to the R5 as your only race machine. Engineered to excel on the most punishing mountain stages and technical descents, the R5 is built for riders who demand the absolute best when the mountains get steep and the competition gets fierce.
