Most modern RDs expect to find a Campagnolo-style dropout (or the newer "direct attach" type). If you have a Simplex-only hanger, that will be an issue.
I also have read somewhere that at some point Simplex started making rear dropouts with integral hangers that included the Campagnolo-style "tang". If that is correct and your frame has one of those (or has a Campagnolo-style dropout), then the hanger issue shouldn't crop up.
Well that really chaps my hide. I was wondering about that... If it's not compatible they do say I can chop it down and put a campagnolo mounting claw (not sure if thats even the right one though for a modern rd) on it. I'm not entirely opposed to it. A little worried I'll mess it up. Maybe I'll buy the rd and just check it before anything else. I can always sell it.
Just to check again since no one replied to that part of my earlier message.. I can use an 8 speed rd on my current 6 speed right?
