Odd-ish request I know, but I am after some white inner tube dust caps, a pair of, dont need to be new, but do need to match and not be dice, or bullets etc.
I have some off white ones, would match Wildgrippers or Magics, but not porc's as they are not actually white. Only for schraeder valves though, you didn't specifiy which type you needed. PM me if these sound like they would work for you.
or find a mate who's getting a frame p/coated white and stick some alloy caps in with it (I did this with 'bars, forks and brake boss bolts and wish I'd stuck all the shed junk in!)
