1993 you could still get those shifters possibly 94, so if your going with the M732 shifters and the M733 brake lever set up any of those parts in those pictures will go will go with that set up not to much changed between 91 and 93 with the Deore XTI have some XT thumb shifters which I'm keen to use. what was the latest date they sold these?
whatever that year is, is the same era I'd like the rest of the groups to be.
