The Cadex 50 Ultra Disc Wheelsystem: New ultralight aero wheels - Cyclingnews

Cadex is a brand under the Giant umbrella but the new Cadex 50 Ultra Disc Wheelset is not a Giant house brand wheelset.

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. .

It makes sense to start with the tyre because it informs the design of the wheel as well.

As with all Cadex wheels, the latest iteration uses a hookless design and focuses on lightweight and aerodynamics.

Cadex already has tyres on the market for general riding but in an effort to move the goalposts even further, the Cadex Aero tubeless tyre meant specifically to cut through the air. .

The new tyres specifically pair with the wide, 22.4mm internal profile, of the latest wheels for a more oval tyre shape when inflated.

For those looking for an advantage with other wheels, the brand states that the "optimized aero profile improves the overall aerodynamic performance of many commercially available wheels.".

The Cadex Aero tubeless tyres use a micro file tread and pairs that with the RR-A Compound rubber.

When it comes to aerodynamics every new wheel has claims of being the fastest but Cadex has a rather transparent and rigorous testing procedure to share along with the claims.

The first step is using the same Cadex aero tyres paired with Cadex 50 Ultra Disc, Enve SES 5.6, Zipp 454 NSW, DTSwiss 50 Arc 1100, and Roval Rapide CLX.

For the last test, the wheels and tyres are the Cadex pieces while three industry-leading race bikes swap out the Giant Propel.

Although the wheels in use are not all the latest version, Cadex shows improvement in every instance. .

To get these results, the Cadex 50 Ultra Disc Wheelset relies on a couple of innovations.

Less visible but just as important, the hub used in the Cadex 50 Ultra Disc Wheelset sees an update as well.

Cadex again claims an advantage here stating that "the CADEX 50 Ultra Disc beats the next best by more than 27%."
