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

Received the tubeless valve stems promptly but haven’t used them as yet. Appear to be solid quality and the perfect size.

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.

Quality was good and conveniently came with the core tool. My only problem was that the valve stems wouldnt seat completely when installed (WTB i19 wheels) as they were slightly too wide and the rubber too hard make an airtight seal, even when the nut was tightened with pliers.

They leak at the base no matter what you do. After spending hours and hours trying to fit these valves (where other valve types would do), I took time to actually review all these 5 stars reviews and realized they are almost all fake. These valves are garbage. Invest few more bucks and get Stans.

These valve stems do not work with the Shimano rims so they were useless to me.

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.

Worked great. Making wheels tubeless isnt for the faint of heart, but these stems worked great.

The valves are absolute garbage.. Wish I could leave no stars at all. They leaked, tried everything under the sun to make it work but they’re useless.. I would not never buy it again..

Works great !

Its cheap and it worked!
