Featuring an all-new 50mm aero rim profile and next-generation R3-C aero hubs, the Cadex 50 Ultra Disc wheel offers superior aerodynamic performance and stability, as well as control in all conditions. The innovative Carbon Super Aero spokes improve efficiency and minimize weight, while the ceramic bearings reduce power loss by up to 30%. The increased internal width of 22.4mm, in combination with the hookless design are optimized for large volume tires. This ensures increased sidewall support and the ability to run lower tire pressures for better grip as well as a more comfortable road feel.
