I have a friend with a mid-90's Trek 8xx bike that has grip shifters. He broke his RD this weekend and needs a replacement. I know that there is little to no difference between an 8 and 9 speed RD. What about a 7-spd RD? My understanding is that the hubs are smaller on 7-spd's but I did not know if that would affect the RD. Also, given the age of the bike, would he notice any difference between any of the lower-end SRAM RD's? Thx.
