In any road race or ride, you face ever-changing situations. Climbs and descents. Fast, flat sections and tricky corners. Group dynamics and solo moves. The new CADEX 50 Ultra Disc WheelSystem targets all these factors. Every component, from the rims to the spokes to the hubs, is engineered to minimize drag with zero compromises. It beats the competition in aero performance, weight, stiffness and overall efficiency.




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.


Baleros Cerámicos

Los baleros cerámicos CADEX duraderos y ultraduros aumentan aún más la eficiencia de rodadura de la maza con menor resistencia a la rodadura y una acción 1,5 veces más suave que los baleros de acero.

Tecnología Hookless CADEX

La tecnología de rin hookless CADEX, que presenta un amplio rin interior y una estructura de fibra de carbono continua y duradera, ayuda a crear una forma de neumático más redondeada para un agarre y manejo superiores, además de soporte adicional en las paredes laterales para tomar curvas, todo sin comprometer el peso.

Tecnología DBL Personalizada

La tecnología Dynamic Balanced Lacing coloca los radios en un ángulo de refuerzo más amplio y para el mismo nivel de tensión bajo la fuerza de pedaleo, produciendo una rueda más rígida y eficiente con una transferencia de potencia sobresaliente.

Lay-up Reforzado con Precisión

El laminado reforzado con precisión CADEX coloca fibra de carbono de alta resistencia a la tracción solo donde se necesita, creando una estructura de llanta fuerte y rígida con un peso mínimo.

CADEX R3-C40 aero hub

La maza aerodinámica CADEX R3-C40 mecanizada con precisión reduce significativamente la carga del balero, y los baleros cerámicos CADEX producen 1,5 veces menos fricción que los baleros de acero.

CADEX Super Aero Carbon Spokes

Los radios de carbono CADEX Aero, ultraligeros y de alta resistencia a la tracción, minimizan la flexión lateral para una aceleración y ascenso más eficientes y cuentan con una forma aerodinámica diseñada específicamente que ofrece características aerodinámicas líderes en su clase, así como una estabilidad superior en vientos cambiantes.
