To win races and break world records, you have to shake up the status quo. That's the thinking of Ironman world champion Kristian Blummenfelt. And that's exactly the vision behind the new Cadex Aero Disc 4-Spoke wheels. Developed with the help of extensive wind tunnel analysis and proven in triathlons, they are the fastest wheels Cadex has ever developed!

The 3mm wider hookless rim improves stiffness, provides more support for the tires during cornering and optimizes airflow from the tire to the rim, for lower drag. The rim inner width of 22.4mm and a continuous routing of Carbon fibers create a more optimal shape of the tire for improved grip as well as handling characteristics, without adding weight.

With its optimized Carbon construction, the Cadex 4-Spoke wheel achieves the best-in-class stiffness and stability-to-weight ratio. Combined with the all-new R3-C40 hub technology and race-proven CADEX Low Friction hubs, the result is unmatched power transfer and efficiency. Disc brakes also add confidence in all weather and road conditions.
