thanks for doing the search. The previous owner did a lot of mods (biopace cranks and slicks among other things) so I don't know what's original. Having a hard time finding shimano model names on the shifters/deraillers. They are the older (thumb) shifters that used to be on mountain bikes though, not the grip shifters listed. The shifters got moved to the stem (a pretty good way of modding old mountain bike shifters to make them stem shifters). Basically he was trying to make a touring/commuting bike for himself and then for reasons he didn't want to discuss had to sell it.
