What's the issue with Simplex drops, DR's?
This is a great, but infectious forum. Browsing this board has piqued some interest in European bikes, but my knowledge of them is worse than pathetic. (Ever since the 70's, all my bikes have been Asian.) I keep seeing offhand comments to the effect that Simplex dérailleurs are required for certain dropouts on Peugeots and maybe some others. Am I reading that correctly? And if so, what's the reason for that?
