I have used Stan's rims, sealant, rim strips and now their valve stems. Stan's tubeless products have always performed well and have set the standard that other companies follow. The competition is getting better at their game because of Stan's reputation, and that's good for all riders.
As usual a great product!!
These work on rims with both schrader and presta valve holes, and so can convert a schrader rim to a tubeless wheel with a presta valve.
I've used a lot of different valve stems for tubeless over the last 14 years. Stans are the original and best. I've had cheap Chinese stems fail but not the Stans.
Works perfectly
Valve stem work great and fit the rim
Work fantastically on the first try. Highly recommended. Easy to use and reliable! You'll spend far more time wrestling with your tire than you will messing with these guys.
