Who makes tubes with no threads
 

I am looking for a lightweight tube that does not have threading all the way down the valve. I usually do not use that silly little knurled nut and the threading just tears up the rubber gasket in my pumps. I thought I bought some Vittoria tubes this way but I just checked my stash and they were all threaded.

Michelin, for one. There are others.

yep on michelin, also torelli

Exactly what I am NOT looking for.

CORRECTION: I didn't pull the link down, they also have 60mm smooth stem tubes.
