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

A much better valve than Stan’s. The oring under the nut fixes another source of leaks and keeps the nut tight.

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.

As described.

Works great, great price
