The Cadex 50 Ultra Disc Wheelsystem: New ultralight aero wheels

Cadex is a brand under the Giant umbrella but the new Cadex 50 Ultra Disc Wheelset is not a Giant house brand wheelset. Although we’ve talked about it in the past, Cadex is a brand with roots back to the mid-’80s. At the time, Giant was looking to build a carbon fibre bike frame and it needed a group who could untether themselves from day-to-day business realities. 

Giant needed a moonshot group and Cadex was the answer to the need. Then the brand disappeared until 2019. This time with a range of wheels but with a mission statement that hadn’t changed. Described in their own words, “CADEX is the pursuit of what many see as improbable, even impossible.” As the lineup has expanded from the initial release, it has continued to mean stunningly light and highly aerodynamic. 

Cadex wheels are some of our favourites and we’ve included the 65mm depth in our list of the best road bike wheels. So far though there’s been a hole in the brand’s lineup right at the most popular modern depth and today’s launch is changing that. The Cadex 50 Ultra Disc Wheelsystem represents an expansion of the available wheel depth. It brings the latest aerodynamic tricks and a new aero-optimized tyre to market for a complete wheel system.
