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

Not much to report. I screwed these valves in, put some sealant into the bottom of the tire, seated it on the rim a little bit, compressor on, et voila, I am riding tubeless (with tubeless-ready wheels, of course). No leaks from the valves or anywhere else after 2 weeks.

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.

The headline says it all.

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

Love the rubber o-ring that keeps the tool on where you need it! These worked great for my tubeless tire conversion

Good for the price

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.

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

Perfect fit for going tubeless

Works great !
