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

Bought these for my Giant Trance 2 with stock wheel set. They fit perfect. Round base so no worrying if the stems are still aligned after installing the tire.

These are working very well in my WTB i35 tubeless 2.8 set up, the rubber O-rings are a plus to get that extra seal.

Bought Stans no tubes version, fought them for a week with no luck. I ordered theses and they worked out great for me, sealed up right away no issues. 2 months in now all good.

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

Its been a month and holding good!

It appears to be well built, but the seal is too small for the valve stem hole on my wheels, and no matter how tight I tried to tighten the nut, it wouldnt seal. Had to buy something else

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

Arrived promptly with no surprises. What more could a customer ask for?

They installation was simple. The rubber ring was a nice addition to keep the seal air tight. Good to know you can get good quality tubeless components without spending a small fortune.

Very nice quality and reasonably priced .. worked perfect for my tubeless tire conversion !! .. will definitely buy again for the next set
