Side Lever Locking Disc Chuck

A locking Presta valve chuck that stays securely connected at 220+psi for road and track situations, allowing both hands to remain on the pump handle, even when inflating disc wheels.

Who’s it for?

The Hiro Chuck is a finely crafted tool for those obsessed with the details as well as the experience of cycling. For high-pressure Presta valve applications, there is no better chuck.
