CADEX 50 Ultra Disc Tubeless

A fast road wheel is a wheel that best manages the various, ever-changing forces of road riding. One of these forces, especially at higher speeds, is drag. Every aspect of this WheelSystem is engineered and designed to minimize drag, no matter the course profile. From the aero profile of the 50mm carbon rims to the Super Aero spokes and all-new aero hubs, it’s a complete system that was developed through exhaustive wind-tunnel testing and proven fastest in its category in real-world conditions.

Whether you’re sprinting, attacking, or taking a big pull on the front, efficiency is your friend. Small gains help you shave seconds, up your average speed, and conserve energy. Nearly weightless CADEX Super Aero carbon spokes deliver wind-slicing speed. Dynamic Balanced Lacing (DBL) technology boosts efficiency by using a wider bracing angle that evens out spoke tension under pedaling forces. An industry-leading weight of 1349g helps improve the system’s lateral stiffness-to-weight ratio up to 41.4% compared to competitor wheels. And an all-new low-friction freehub with ceramic bearings further reduces power loss by up to 30%.

To ensure that the least amount power is wasted, the lateral and torsional flex of wheels must be minimized. On the front wheel, the CADEX 50 Ultra has the highest lateral stiffness among its competitors, beating the Zipp 454 NSW by 18.8% and Roval Rapide CLX by 40.6%, all while remaining the lightest of the group. For the rear, the CADEX 50 also has the highest lateral stiffness among competitors, more than 14% stiffer than second place. In terms of transmission stiffness, the CADEX 50 Ultra Disc beats the next best by more than 27%, guaranteeing superior power transfer.

Aerodynamic efficiency and ultralight weight are important, but a truly transcendent road wheel must also inspire confidence while descending, cornering, or battling nasty crosswinds. The 50mm aero rim profile and Super Aero spokes balance straight-ahead speed with total control in all types of conditions. In addition, a broad inner rim width (22.4mm) and increased hookless bead width (3.8mm) provide greater support for higher volume tires and enhance sidewall stiffness for better tracking and cornering performance.
