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

I have a standard rim and the rubber part was slightly too big to fit in the hole. I ended up tightening the nut really tight and it still seals so it isnt a huge deal. The stems seem solid and durable. Pretty happy with this product. Only knocked a star off because of the fit.

Good price, fast shipping. Now, if I could only remember where I put them ...

As expected.

Great valves for the price! Get these instead of the premium brands!

I love the stems they are just what you need to go tubeless on your bike.

Was reasonable

Valve leaks around the base like a few other reviews said. Spent hours trying to figure out the problem, thought leaking at spoke nipples was due to a leak in the tape but came to realize it was the valves. Adjusted multiple times and added sealant but nothing will get these valves to stop leaking. Don’t waste your money or time buying these!

The thing that sets these valves apart is the tiny o-ring thats inset within the threaded nut, adding extra seal outside the rim. This also keeps the valve from wobbling loose. These will be my go-to valves for tubeless. Better quality than Stans, imo, and thats saying something.

Could never get them to stop leaking.
