Excelling across race conditions, the aerodynamic DURA-ACE C50 balances low weight and responsive handling. Carbon spokes, a refined rim profile, and updated hub architecture create a wheelset equally at home on climbs, rolling terrain, and high-speed racing.
New cup‑and‑cone bearing design remains at the heart of DURA‑ACE because it delivers what performance riders value ride after ride: smooth rolling under real-world cornering and sprint loads, long-term durability, and the ability to keep everything precisely adjusted.
The result is a wheelset that stays smooth, reliable, and confidence‑inspiring. Not just when it’s new, but season after season, with new waterproof sealing to keep performance consistent in all conditions.
The R9300 DURA‑ACE cup‑and‑cone system is fully serviceable, allowing the bearings to be removed and maintained individually. Instead of replacing the entire hub, worn components can be refreshed as needed, helping preserve performance and extend the life of the wheel.
