Cadex is a wheel and components manufacturer founded by Taiwanese bike company Giant in 2019 with the aim of creating the best-performing cycling components.



In its current iteration, Cadex has only been around since 2019, but the name has a much longer history dating back to the late 1980s when bicycle brand Giant unveiled a new carbon fibre frame, the Cadex. The new bike was one of the first carbon fibre bikes to be produced on a mass scale, one of the forebears of the now carbon-dominated cycling industry.

After a long spell on the sidelines, Giant revived the brand in 2019 as it became the name for a new collection of carbon fibre wheels. Like many dedicated wheel brands, this operation has since expanded to include multiple other components, including handlebars, saddles, tyres, and it’s even revived its frame heritage with the Cadex Tri frameset.

Behind all of these products is the brand’s aim of creating the best cycling components available, something achieved through extensive research and collaboration with professional athletes.

This approach has led to multiple developments, including the brand’s state-of-the-art, high-pressure moulding process, aero carbon spokes, and an asymmetrical disc profile.

Cadex’s products are now regularly used in elite-level competitions across multiple disciplines including road, gravel and triathlon.

  • The Cadex name first emerged in 1987 when Giant used it for its new carbon fibre road bike. It was one of the first carbon fibre bikes commercially available.
  • In 2019, after a long stint laying dormant, the Cadex name was revived by Giant who used it for its new brand of bike wheels. Although sitting under one umbrella, Cadex is a separate brand to Giant.
  • Despite only being revived in 2019, Cadex wheels were being used in the WorldTour peloton as early as 2016 when CCC where spotted using unbranded wheels with “#overachieve” on them.
  • From the start, Cadex introduced a range of new technology, including Dynamic Balanced Lacing (DBL) technology which is used to custom calibrate the spokes.
  • Alongside the wheels, Cadex also unveiled the Boost Saddle and has since expanded its range to include handlebars, tyres and a triathlon frame.
