OUR STORY MAKES THE DIFFERENCE

In 2022, our adopted VONOA carbon spokes made their debut at the UCI WorldTour and Tour de France—proving their performance on the sport’s biggest stage. Today, as PHi, we carry forward this legacy: blending professional-grade engineering with everyday accessibility. Our mission? To “Explore the Limits of Carbon” and bring high-end, patent-backed carbon fiber components (including wheel sets and spokes) to every rider across Europe—without the luxury price tag.

HANDMADE QUALITY

We are proud to deliver handmade quality from China – it’s all about craftsmanship. Craftsmanship lives through the people who ply their trade; through their experience, knowledge and commitment. We believe that quality lies in understanding every step of the production process. This is the only way that we can manufacture unique products and guarantee consistent quality. We believe that quality is defined by top-class workmanship, durability, unparalleled performance, and of course how the product looks! At PHi, components are simply demoulded, the protruding burrs are removed and finally they are finished. The result is that the fibre structure of the carbon remains clearly visible. This procedure is mercilessly honest and there is no margin for error during the laminating process. The only way to get this classy look and to get the most out of carbon is to work with precision. You get what you see – pure carbon! We don’t need to hide our components under a layer of paint.

BEHIND PHi

At PHi, we merge decades of production expertise, uncompromising quality control, and innovative spirit to redefine what’s possible. For us, carbon isn’t just a material—it’s a promise: premium performance, built to last, for riders who demand the best.
