Cadex 50 Ultra Disc Wheels: 50mm Aero Profile, Carbon Spokes & 1,349g Weight

Engineered in the wind tunnel to combine high-profile speed with climbing wheelset lightness, the Cadex 50 Ultra Disc Wheels (also known as CADEX Ultra 50 Disc Tubeless) represent the pinnacle of technology for Aero and All-Rounder road bikes. Weighing a total of just 1,349 grams per pair, this carbon wheelset combines a 50mm aerodynamic rim with a 30mm external width, Super Aero carbon bladed spokes, and low-friction R3-C40 hubs with ceramic bearings, delivering superior crosswind stability and explosive sprint responsiveness.

Key Technologies of the Cadex 50 Ultra Disc Wheels

• Super Aero Carbon Spokes & DBL Dynamic Balanced Lacing: Ultra-high tensile strength carbon composite spokes feature a flat, wing-shaped profile that slices through the air and minimizes lateral flex during out-of-the-saddle sprints. Patented Dynamic Balanced Lacing (DBL) technology brings spokes to ideal tension under real pedaling loads (rather than static wheel builds), maximizing power transfer to the rear wheel.

• R3-C / R3-C40 Aero Hubs & CADEX Ceramic Bearings: Precision-machined hub shells eliminate axial load on the bearings. CADEX ceramic bearings are 1.5x smoother than steel and reduce frictional power loss by up to 30%, while the R3-C40 rear hub integrates a 40-tooth ratchet driver for instant engagement.

• Reinforced Carbon Lay-Up & 3.8mm Bead Wall: Utilizing high-modulus carbon fibers and high-TG resins positioned only in high-stress torsional zones keeps weight down to 595g front and 754g rear, while delivering class-leading lateral stiffness.

Hookless Rim with 22.4mm Internal Channel & Tire Matching

The Cadex 50 Ultra Disc wheels feature a continuous carbon fiber Hookless rim structure with bead walls thickened to 3.8mm per side, dramatically increasing impact resistance and eliminating the risk of pinch flats.

The wide 22.4mm internal channel (paired with a 30mm external width) is optimized to work in symbiosis with tubeless tires from 700x25c to 700x32c:

• Pure Aero Setup (25c / 28c): Paired with CADEX Aero Tubeless or CADEX Race GC Tubeless 28mm tires, they create a seamless transition between the rubber and the 30mm rim outer wall, eliminating turbulence.

• Cornering Support & Lower Pressures: The 22.4mm channel gives the tire a rounder profile that supports the sidewall when cornering, allowing you to run lower pressures for increased grip and better road vibration damping.
