In restoring a vintage bike you always come to that moment when in sourcing parts-unobtainium.
Such is the case for my Nishiki Cresta grand touring bike currently under reconstruction, it came with a unique and funky rear derailleur the Suntour Mountech Tri-pulley. Yes, it has three pulleys which allowed a longer length of chain to be wrapped and the derailleur arm to be raised a little higher to be safer from damage. From threads in the forum people are well pleased with this derailleur and note that its innovation worked for its time.
But with all vintage restorations that time has passed and finding a source for a part that was unique in its age is...
.
So any help, suggestions, secret places to look you can recommend would be greatly appreciated.
And since I have none, sorry can't post a picture of this derailleur, other that from this catalogue page.
