Man this bike wrenching research is hard stuff! If it is true that even a campy long cage RD will not handle a max 32 and I need to get a RD anyway, how about I get a SRAM X.7 long cage which absolutely says I can go to 34 max? Throw in a ShiftMate to keep the indexing correct, slap on a SRAM PG-970 9 speed remembering to adjust the limit screw or slap on an IRD 10 speed 11-32 with no adjustment needed?
Bonus question: I have Zipp team CSC wheels with a SRAM 11-28 cassette so I think I have a shimano compatible hub/freewheel and not a campy one?
