The Cervlo R5 Red AXS is purpose-built to get to the summit quickly. While summit finishes bring glory and fanfare, they’re rarely the day’s only challenge. Races might not be won on descents, but they’re definitely lost there. The R5 isn’t just a climbing specialist; it’s a complete mountain weapon that carves hairpins as confidently as it conquers gradients. This latest generation preserves the legendary handling and descending prowess that have defined the R5 from the beginning.

The new R5 frameset comes in at 73g lighter than its predecessor, representing an engineering revolution. The frame sheds weight to just 657g while strategically increasing stiffness for power transfer and compliance for comfort. Every component has been reimagined, from whisper-thin seat stays to refined tube profiles that eliminate excess material without compromising structural integrity. Details like integrated brake mounts and streamlined fork design contribute to the impressive weight reduction.

The standout innovation is the integrated one-piece handlebar and stem system, which saves 134g while incorporating aerodynamic principles borrowed from the S5. Geometry alignment with the S5 ensures consistent positioning across Cervlo’s road lineup, whether climbing mountains or chasing breakaways. Practical improvements include tool-free bearing cap swaps that don’t require re-cabling and direct-mount brakes that accommodate 160mm rotors natively.

Performance improvements extend far beyond weight savings. Bottom bracket stiffness increases 13% for superior power transfer, while head tube compliance improves 8% for enhanced comfort during extended climbs. The redesigned bottom bracket height perfectly accommodates 29c tires, delivering improved aerodynamics, rolling resistance, and cornering grip. Whether pursuing personal records or podium positions, the R5 delivers uncompromising climbing performance that sets the standard.
