The Cervlo R5 Dura-Ace Di2 exists for one reason: to conquer climbs. While summit victories grab headlines, races also include technical descents where leads can slip away in an instant. The new R5 is designed to carve through descents and switchbacks with the same confidence it displays on climbs. This new generation preserves the celebrated handling characteristics and downhill confidence that have defined the R5 legacy.

Cervlo achieved a dramatic 73g overall weight reduction to the frameset through a comprehensive redesign while enhancing stiffness where power matters and improving compliance for rider comfort. The reimagined 651g (size 56) frame showcases advanced engineering through ultra-slim seat stays and optimized tube geometries that strip away unnecessary material while maintaining structural integrity. Weight savings accumulate through countless refinements, from integrated brake systems to streamlined fork construction.

The breakthrough one-piece cockpit integration eliminates 134g compared to traditional setups while adopting aerodynamic principles from the S5 platform. Updated geometry ensures consistent position between climbing and aero configurations, allowing for seamless transitions between different riding scenarios. Intelligent engineering touches like the updated bearing system enable maintenance without cable disruption, while integrated brake mounting eliminates adapter weight.

Enhanced ride quality accompanies the weight reduction. Bottom bracket stiffness jumps 13% for superior power transmission, while head tube flexibility increases 8% for improved comfort during extended efforts. The revised bottom bracket height optimizes 29c tire integration, boosting both aerodynamic performance and road contact. Combined with Shimano’s premium Dura-Ace Di2 electronic drivetrain and 4iiii’s dual-sided power measurement, this R5 represents the ultimate expression of climbing bike evolution.
