Maxxis Ultralight tube question

[piano,piano]

Could anyone please tell me if Maxxis Ultralight 700C tubes have threaded or smooth valve stems? I tried looking around online but couldn't find a decent enough image to tell. Thanks.

Pretty sure they're threaded. Been a while since I bought any but if I recall correctly they're threaded.

All of them I ever used were threaded. I'm now using lightweight Michelin tubes that are non-threaded.

Thanks. I used to use threaded (Continentals) until I realized that they were destroying the gasket in my pump. I've been using Michelin Airstops, but wanted to try a lighter tube. I think that I'll try the Aircomps.
