SILCA HIRO Presta Chuck | Grips Presta Valves Tightly for No-Leak Pumping

All metal locking chuck  |  Seals on as little as 10mm of valve  |  Adjustable pre-load  |  Threads into any Schrader chuck

Leaking chucks are a thing of the past with the HIRO locking chuck.

It locks onto Presta valves with a lollipop style side lever, the same mechanism Josh spotted a Euro-Pro mechanic running on disc wheels at the Dauphine Libere, on chucks that were nearly impossible to find outside Japan.

HIRO brings that design to the rest of us, refined and made available for any Presta valve you throw at it, including short valves and disc wheels.
