From the winds of Kona to training rides in unpredictable conditions, the CADEX Aero 4-Spoke combines proven aero performance with confident handling and control. The added crosswind control of the 4-spoke design makes it a top choice for pros like Ironman World Champion Kristian Blummenfelt, who often uses this as a front wheel combined with a CADEX Aero Disc in the rear. The superlight and stiff carbon rims are 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 grip. It all adds up to best-in-class aerodynamics, unbeatable efficiency, and total control in all conditions.
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.
