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

As described.

Worked great with Stans tape on a road bike rim. No issues - sealed on the first try.

Good stuff

Was as described and shipped fast

No surprises here. Great price. Valve core was easily removed. Feels good quality. Holds the air like its supposed to. Im happy.

Best Tubless valve stems at a Great price. The 40 mm length is perfect. Much better than the standard length. The Buyer gets you the items super fast as well.

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

Good

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

These are better than the Stans valve stems. The extra o ring seems to help seal the rim up from air leaks. They also seem physically more robust.
