R5 Ultegra Di2 (2026)

The 2026 Cervélo R5 Ultegra Di2 is the latest evolution of Cervélo’s most iconic climbing platform — engineered to be lighter, stiffer, and faster where it counts. With a frame heritage that has conquered Mont Ventoux and the Tour de France Femmes, the new R5 continues its legacy of performance at the highest level.

At just 5.97 kg in top-tier builds, the R5 delivers explosive acceleration and precise handling on climbs and descents alike. Its advanced carbon construction offers pro-level stiffness and responsiveness, while Shimano’s 12-speed Ultegra Di2 wireless groupset provides seamless, instantaneous shifting and integrated dual-sided power measurement via 4iiii Precision Pro. Paired with Reserve 34/37 carbon wheels and Vittoria Corsa Pro Speed TLR tyres, this setup blends lightweight efficiency with confidence-inspiring control.

Whether you’re chasing elevation PRs or racing up alpine passes, the R5 Ultegra Di2 redefines what a climbing bike should feel like — agile, composed, and relentlessly fast.
