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.

Great upgrade for my Superpista, except...
This works exceptionally well and is a fabulous upgrade for my Superpista pump. However, it would be great if Silca could make/provide a locking mechanism that secures this to the pump. It doesn't fit the standard attachment that came with the pump and now the cable flops around, falls on the floor, scratches the pump up during travel, etc. It's an annoying oversight which doesn't square with my general experience or impression of Silca products.

Hiro Presta Valve Adapter
The perfect solution for my TT rear-wheel disc, and for all my other Presta valve pump head usage. No other Presta valve adapter performs as fine as the Hiro. Highly recommended.

Not usable
I bought this expecting to be able to attach it to my air hose quick release. It has threads.
