Hi gang, Thanks to everyone who provided info on the Huret Duopar mounting. I dug out my steel version, purchased somewhere (i-bob list maybe?) a few years ago out of curiosity. It appears to have the funky washer with the tab, so I suspect it'll fit on my conventional dropout. The only remaining question is: how does this stuff all go together? Does anyone have any instructions, or perhaps an exploded-view diagram?
many thanks, Steve Kurt Peoria, IL (deciding it's better to read the instructions instead of botching it and trashing the derailleur)
