Hey guys I'm still in a pickle of setting up my 1940's Simplex Tour de France changer aka derailleur (this derailleur was called changer back in the old old days) and cycleops recommended me to ask someone on here who has messed with this type of derailleur before to get some tips and guidance. I'll post pictures of the derailleur a little later. Also, do you think it'll work on my vintage Fuji S12-S LTD road bike? If not then what kind of bike do I need to look for (or possibly build or make)? Thanks a bunch!
