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. Featuring wind-tunnel tested asymmetrical shaping, an all-new CADEX Low Friction R3-C40 aero hub with ceramic bearings and a broad 22.4mm inner rim width, it delivers best-in-class aerodynamics, unbeatable efficiency and total control.
