Silca HIRO v2 Side Lever Locking Presta Chuck : Silver

Season:0

Brand:Silca

Code:SIAMPUCHUASY006

Whilst working with Team CSC at the Dauphine Libere, Josh Poertner, now owner of Silca, noticed one of the mechanics using the most amazing little chuck to manage 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 as they were very hard to come by, and even harder to get replacement parts for. He followed all of that up by refusing to let any of the other mechanics even touch the thing!

Fast forward 10 years and Josh - and by extension Silca - has been fascinated with creating a better, disc wheel compatible locking chuck. One which can hold 300psi (not that you would do that..) one that was made from even finer materials, like Stainless Steel, and one that had the history and legacy of SILCA behind it so that it could be purchased and used knowing full well that replacement parts would be available for the next 100 years.

When taking the new SILCA side-lever prototypes to Europe, the mechanics were very clear in their demands: single hand usage, 250+psi capability for road and track situations, 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 as well as on innovating some 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.

Silca decided on stainless steel as the primary material for it's environmental friendliness compared to chrome plated steel and for it's extreme durability and chemical resistance when compared to all other metals. They obsessed over the right amount of knurl, rough enough to be handled very precisely even when covered in grease or wet, yet not so much that those of us with office jobs during the week end up with shredded fingers. By the end of the prototype period, the mechanics nicknamed the chuck 'Hiro' partially as a nod to the Japanese heritage, but also due to the shared pronunciation with the English word 'Hero'. 

The Side-Lever Locking Chuck is classic SILCA quality and manufacturing in every detail.  100% made in the USA from fine stainless steels, 100% re-buildable, and utilizing a new, high-tech elastomer gasket design - the 254 - which is already available for replacement sale and like all other SILCA gaskets, will remain available for the next 25 years and probably longer.

Despite being ideal for Disc wheel applications, the Hiro v2 is also just as satisfying to use on non-discs!

    It is a tool which 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. It is not a screwdriver or a hammer, it is an intricately machined, high-precision device with very unique features and user adjustability, learn how it works and you will find great pleasure in it's operation. 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.
