converting to tubeless - valve stem hole question

[Joe Garfield]

This thread has been helpful for me. I brought my wheel to a 'motorcycle shop' to get a new valve stem, and the guy said my wheel had an odd-sized hole (smaller than he expected) and therefore he didn't have the right valve stem. It sounds like he had the 'car' sized stems which are also used on newer bikes. This, along with the hack job performed on my steering stem, proves to me this guy should not be in business (or at least never get my business).

So will any 'motorcycle' valve stem work? I want to get an angled one for my rear wheel.

Yes - the motorcycle valves shown here should work. ( I hesitate to say 'any' since I am not aware of all)

BTW, my valve install and mounting went well. for the concave F wheel I pictured above, the countersinking worked well. Also on that same bike the rear had a flat center section so I could have gone with the flat washer motorcycle valve if I had it, since I had the one with the center rubber part, I make a small diameter countersink to accommodate the small rubber part and let the large rubber washer part rest on the flat of the rim.
