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 CADEX Aero Disc WheelSystem is their fastest wheel ever created.

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-in-class aerodynamics, unbeatable efficiency, and total control in all conditions.

Features:

• 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, and CADEX ceramic bearings produce 1.5 times less friction than steel bearings.
• A 22.4mm inner rim width and durable continuous carbon fiber structure creates a rounder tire shape for superior grip and handling as well as added sidewall support when cornering, all without compromising on weight.
• Increased rim bead width of up to 3mm per side enhances rim bead stiffness, offering better support for tires when cornering and improving air transition from the tire sidewall to the wheel for improved aerodynamics.
• Unique asymmetrical disc profile augments structural balance.
