Zipps 303 Firecrest wheelset features rim technology that has been designed to make handling top-class, especially when cornering. This rim design also provides good stability when riding with internal ridges that lock the tyre's bead in place, improving overall performance and making for a faster and more reliable ride. By going tubeless, the 303 Firecrest's remove any risks of getting a pinch flat, providing peace of mind when racing. By being tubeless, the 303s can be ridden at a lower tyre pressure without hindering performance.

Featuring 77/177D hubs, the 303s are versatile and compatible with any bike with the ability to switch the end caps and tailor to either QR's or thru-axles.
