i72 Tubeless Valve Stems 40mm Presta Pair - Brass Made with Core Remover Tool, Round Rubber Base with O-Ring for Better Sealing

Great if youre trying to do the Gorilla tape method

Product is great, as expected

Outstanding product at a fraction of the “price”..!

Seals perfectly

As expected.

These are better than the Stans valve stems. The extra o ring seems to help seal the rim up from air leaks. They also seem physically more robust.

Exactly as expected, the core removal tool is perfect and a nice plus

No surprises here. Great price. Valve core was easily removed. Feels good quality. Holds the air like its supposed to. Im happy.

It works. The little black o-rings seems useless.

Yes I will admit these things are a great deal. But with their low price they lack durability. I set them up with no problems but soon realized their weak points. If you do not fully tighten them to the rim they will leak a lot of air quickly. Overall if you are looking for a quick way to go tubeless these are a good options but if you are serious about cycling I would dish out an extra 10 dollars and go with a nicer pair
