I've used these types of valves on both cast wheels of my old Fireblade and the spoked wheels on the Adventure,
When I bought these types back in the late 90's I had to source them from Italy. They were kind of expensive to do that way.
These I got from Wunderlich.
These have been in my wheels since about 2005 I think. I can't remember for sure. I have replaced them once each end.
