I have a few nuts, similar in size to the nuts that come threaded on Presta valve stems, that have a shoulder notched into them. They thread down onto Presta valve stems on Schrader-drilled rims to hold the stems in place. Quite handy, but I can't find a source for more. Does anyone know where they can be found, bags of a few dozen or even 100 if I have to buy bulk?
Thanks! Bill Karow hoarding 27" rims, Schrader or Presta at this point, for his old fleet in Windham, Maine
