The HIRO locking chuck is the ultimate solution for secure, leak-free inflation on any Presta valve setup. Built from full metal construction, the HIRO is engineered for precision and durability, putting an end to the frustrations of leaking chucks once and for all. Its sleek, compact design allows it to seal tightly on as little as 10mm of exposed valve, making it ideal for hard-to-reach valves, including those on deep-section rims, disc wheels, and short-valve tubes. Whether you're inflating race-day wheels or working on your training setup, the HIRO delivers flawless performance every time.

One of the HIRO chuck’s standout features is its adjustable pre-load mechanism, which allows you to fine-tune the clamping force to your specific valve and setup. This ensures a secure hold without the risk of over-tightening or damaging the valve stem. It's especially useful for disc wheels, provided you have access to the valve opening from both sides. With the HIRO chuck, you’ll get a consistent, airtight seal—no more wasted pressure, no more second-guessing your inflation accuracy.

Designed for versatility and ease of use, the HIRO threads directly into any standard Schrader-style chuck, making it a universal upgrade for nearly any pump setup. Whether you're a pro mechanic, competitive cyclist, or just someone who demands the best from their tools, this compact, high-performance chuck is a must-have addition to your inflation arsenal. With its smart design, rugged build, and flawless seal, the HIRO locking chuck makes every inflation smoother, cleaner, and more efficient.
