The Cervlo R5 Ultegra Di2 has one purpose: get to the top, fast. But summit finishes are only part of the story. Climbs may win glory, yet races can just as easily be lost on the way down. Thats why the R5 isnt just a climbing machine; its equally confident carving through hairpins as it is powering uphill. This latest generation continues the legendary handling and descending stability that riders have trusted from the start.

Now even lighter, the R5 frameset sheds an impressive 73g overall, weighing in at just651g (size 56), delivering increased stiffness where it matters most while adding comfort where you need it. Cervlo re-engineered every detail, from ultra-thin seat stays to refined tube profiles that shave grams without sacrificing strength. Even subtle updates, like eliminating brake adapters and refining the fork design, contribute to meaningful weight savings.

A standout upgrade is the new one-piece handlebar and stem, saving 134g while borrowing aerodynamic shaping from the S5. The geometry now mirrors the S5 as well, ensuring your riding position remains consistent whether youre on your climbing bike or aero rig. Practical touches, like a bearing cap system that allows component swaps without re-cabling and direct-mount brakes designed for 160mm rotors, round out the smart refinements.

But the R5 isnt just about cutting weight. It is about elevating performance. Bottom bracket stiffness is up 13% for more efficient power transfer, while the head tube is 8% more compliant for comfort on long ascents. A lowered bottom bracket accommodates 29c tires, improving both grip and aerodynamics. Whether youre chasing a KOM or aiming for the podium, the new R5 sets a new standard for climbing performance.
