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

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.

So finally decided to get it. I've had a working Specialized pump for years & it recently wasn't clamping well onto valves especially the new non threaded TPU tubes without leaking. Was looking into replacing it. Got this instead. Love it. Works great with the TPU tubes. No leaking, very secure and easy to clamp on. In addition works well with pumps (like a Lezyne) that have a schrader threaded piece. Lightweight and can see possibility of carrying for long rides for in the fired flat with small pump.

Worked great on getting to my full carbon wheel. Was a little tricky at first. Very sturdy and seems like it will last. For the price, would have been nice to throw in another gasket, which seems to be the only real wear part. $10 for an extra one was less than ideal. I tried a basic stove pipe valve and it was junk compared to this. I am very happy with it overall.

Love this thing - so much easier to use than an adapter for TT disc wheels.

I have another copy of the Hiro side-lock chuck and it is very good, easy to use and doesn't leak. However, due to someone applying the wrong bar code sticker on the box, I could never get Amazon to deliver the Hiro chuck as ordered--the standard Presta chuck was delivered instead. I returned two of them, and finally ordered Hiro chuck directly from Silca.

Bought this chuck after reading about the most expensive Chuck on the Planet and found that it is (almost) worth it's high cost. There is nothing else like it, and it really does work. Do you need it? Probably not, but if you can spare the change, it really is a game-changer when it comes to convenience and ease of use. No more fumbling around to keep a lesser chuck on the valve, this one works the first time, every time. It does take some adjustment to get it to bite on the valve stem, and the polymer seal will last a lot longer on unthreaded stems, but is easily replaceable when it wears out.
