Silca Hiro Side-Lever Locking Presta Chuck

Bullet-proof high-pressure, disc compatible chuck for high pressure situations.

Years ago, SILCA's owner was working with the Team CSC at the Dauphine Libere when he noticed one of their mechanics using the most amazing little chuck to inflate disc wheels. It was unlike anything he'd 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 they were made in Japan, and coveted by all the Euro Pro mechanics because they were very hard to come by, and even harder to get replacement parts for.

Fast forward 10 years and SILCA has developed a better stainless steel disc wheel-compatible locking chuck, that can hold 300psi and has the history and legacy of SILCA.

During development of the the new SILCA side-lever prototypes in Europe, mechanics were very clear in their demands: single hand usage, 250+psi capability for road and track, and at least a year of service before replacing gaskets (the equivalent of 10 lifetimes of use for the rest of us), and NO hose clamps!

SILCA worked tirelessly on these requirements and new features, like a unique rotating head which allows the chuck to more easily align with the valve stem and eliminates hose twist, regardless of wheel orientation. By the end of the prototype period, the mechanics nicknamed the chuck "Hiro" as a nod to the Japanese heritage and the shared pronunciation with the English word "Hero." Team mechanics joked, "I have 5 minutes to fill 9 disc wheels to 9 different pressures using compressed Nitrogen before the TTT. I need a Hiro!"

Please Note: The Hiro Chuck is a finely crafted tool for those obsessed with the details as well as the experience of cycling. It's a tool that rewards knowledge and understanding of how it works; please expect to spend some time acquainting yourself with the function of the Hiro before you use it. You will smile every time you use it and you will amaze onlookers in the track infield at your ability to achieve any pressure without holding it in place, and you will someday hand it down to your children, who will replace the gasket and use it for another 25 years. Passion. Precision. Performance.
