Hiro Side-Lever Locking Presta Chuck | Presta valve | small space | short valve | secure universal fit

It does a good job

I've read all the positive reviews on this with the only negative being the price. Price didn't bother me as long as it was a good product. I've watched the online vids, I'm deffo using it correctly but this is the leakiest thing ever. It's worst than our defence and I'm a Liverpool fan. It's going back.

Sehr guter Artikel, kam allerdings mit eindeutigen Gebrauchsspuren bei mir an.

Works very well on TPU tube valve stem, adding significant value, but great on standard valves for tubeless setups and butyl tubes, too. No stressing stems with traditional clamp on heads, no unscrewing valve core when using screw on heads. Adjust preload, push on, turn lever, get immediate pressure reading, and pump. Easy to use, versatile, and better for valve stem health.

Prachtig stukje techniek! Sluit het ventiel goed af en de klemkracht van het rubber is instelbaar.

Tut genau das für was es entwickelt worden ist. Und weil manche schreiben, dass der Kopf nicht dicht sein soll, man kann vorne durch drehen die Abdichtung vor dem schließen des Hebels anpassen. Benutze diese auf einer kleinen elektrischen Pumpe und so werden alle paar Tage die Reifen vor der Ausfahrt auf Solldruck gebracht…

I was dealing with a lezyne thread on pump head, either using tubeless or latex tubes im constantly adding 4-10psi. Not only the threading, i have two tubless valves on my wifes gravel bike that it just would not work on. This silca chuck head solved ALL my issues, it has never failed to seal the first time. I ride 3-4 times a week, with airing up 4 tires i save 5-8 minutes a day on top of being completely frustration free. One of the best cycling related products I've purchased.
