Two questions.
1) Will the below derailleur run (index properly) 8 speed ok? or 9? or 10?
2) I can't help but think it's a bit of a cheap way to attach a derailleur - the hanger is inbuilt to the derailleur not the frame. I wonder if replacement derailleurs are available, or does one tend to buy a better frame when it goes wrong?
I'm thinking it'll run 8 ok, as a 6 speed chain is the same size (width) as 8. Another part of me remembers that most shimano derailleurs have the same pull ratio, but I'm not sure if that is affected by chain width. Finally I'm not sure about the quality of the derailluer and it's ability to cope with finer rear gear tolerances, i.e. more speeds.
