Years ago while Josh was working with the Team CSC at the Dauphine Libere, he noticed one of their mechanics using the most amazing little chuck to manage the disc wheel inflation. Unlike anything he had seen before, it was all metal and used a 'lollipop' lever on the side to lock onto the valve stems in disc wheels. The mechanic explained that these were made in Japan and were coveted by all the Euro-Pro mechanics due to their scarcity. So Josh set out to improve the design and make it available to cyclists everywhere.
