I have a bit of a mystery on my hands, one I'd like to solve.
I have a Huret Jubilee rear derailleur with what appears to be the original hanger bolt for a Campagnolo drop-out hanger. I also have the special purpose-made "claw"--the stop that fits over the bolt, with adjusting screw, to position the derailleur properly.
The problem is, the hanger bolt appears to have too many threads on it. When I tighten down on the thing it tightens all the way down, rendering the derailleur body immobile. I know this is not how it's supposed to work...it's supposed to work like a Campagnolo or Suntour..the derailleur is supposed to rotate around the bolt, because the threads end and the bolt stops just short of the derailleur body, leaving a bit of room for the derailleur to move.
Any solutions, anyone? Like, a bolt that will actually work right in this configuration?
I'd really like to use this derailleur.
France is a lovely place, but I really hate the french for their insistence on making their stuff *different* from everything else. Different threads. Different steerer-tube sizes. Different SEAT tube sizes. Different seatposts. Different drop-out hangers and derailleur mounting methods. It's just perverse, imho.
