SILCA 'Hiro' Side Locking Lever Chuck - Carbon Steel

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.

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.

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.

Perhaps I will get better at it over time. Right now I have a hard time with one handed operation and two hands between the spokes is hard to do.

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.
