Silca Hiro V3 Carbon Steel Side Lever Locking Disc Chuck

The Silca Hiro V3 Carbon Steel Side Lever Locking Disc Chuck is unlike anything you have  seen before - it is all metal and uses a 'lollipop' lever on the side to lock onto the valve stems in disc wheels. Leaking chucks are a thing of the past with the HIRO locking chuck. Use it on short valves, disc wheels, and any other Presta valve you can throw at it.

• Full metal construction
• Can seal on as little as 10mm of valve
• Adjustable pre-load for custom fit
• Disc-wheel compatible - Must have valve access from both sides
