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.

OUTSTANDING!
Though it is a little on the big and heavy side for an air chuck, this thing is exactly what an air chuck should be! No screwing around threading on lesser chucks that always seem to leak, as well as being supremely well made. If you’re on the fence about spending on an air chuck more than what some people pay for an entire pump, don’t be. One use and you’ll wonder why you didn’t know about this chuck sooner.

Craftsmanship is fantastic
Beautiful design and craftsmanship . Does not "pop" off at high pressure (170PSI). Worth the money. Looks as if it will last forever.

Hiro is a hero
Just a very simple, easy to use, hands free Presta valve inflator. I now have one on my floor pump and got a second to use with an air compressor and inflator set-up.
