CADEX Aero Disc Tubeless Wheel


  • Super Aero Rim Shape features wider external dimensions for a maximum aerodynamic advantage in the most common wind directions when paired with CADEX Aero Tubeless tires
  • Ultralight 18k carbon composite creates a stiff and stable wheel structure with class-leading torsional and lateral stiffness.
  • Precision machined CADEX R3-C40 aero hub significantly reduces bearing load
  • CADEX ceramic bearings produce 1.5 times less friction than steel bearings.
  • Unique asymmetrical disc profile augments structural balance.


There is no greater proving ground for an aero wheel than an Ironman triathlon. It’s 180km, just you against the wind. No drafting, no hiding. Chosen by some of the world’s fastest pros including Olympic Ironman and Sub7 champion Kristian Blummenfelt, the all new Aero Disc WheelSystem is the fastest wheel ever created by CADEX. The superlight and stiff carbon rims have an asymmetrical design shaped by exhaustive wind-tunnel testing and data. The all-new R3-C40 aero hub with ceramic bearings reduces friction by up to 30 percent over the previous generation. And the 22.4mm wide hookless rims create a seamless integration between the rim and tubeless tire for improved rolling resistance, increased sidewall support, and better cornering grip. It all adds up to best-inclass aerodynamics, unbeatable efficiency, and total control in all conditions.
