Silca Hiro Side Lever Locking Disc Chuck V2

Yes, as long as your floor pump hose ends in a Schrader-style connection. The Hiro Side Lever is designed to thread onto standard Schrader fittings, allowing you to use it with most high-quality floor pumps.

Absolutely. The Hiro is specifically engineered for disc wheels and tight clearances where a standard pump head might be too bulky or difficult to attach. Its low-profile design ensures you can easily access the valve stem without obstruction.

One of the best features of the Hiro is that it is 100% rebuildable. You can adjust the gasket pre-load to compensate for wear, and if the seal eventually fails, you can simply replace the internal elastomer gasket rather than buying a new chuck.

Yes, it is fully compatible with tubeless tire setups. Because it provides a secure, locking seal on Presta valves, it works perfectly for the high-pressure inflation often required to seat tubeless tires.

The Hiro is designed to lock onto valve stems as short as 10mm. This makes it an excellent choice for wheels with deep rims or unconventional valve setups where other chucks struggle to get a grip.

No, that is the primary advantage of the side-lever locking mechanism. Once you lock the lever down, it creates an airtight seal that stays securely on the valve, allowing for hands-free inflation even at very high pressures.
