I have a lovely Pinarello with a 7400 dura ace groupset, however the shifters recently gave up working properly. Rather than buying some more expensive Dura Ace downtube shifters, I tried to fit some more modern SL-R400 shimano 8 speed shifters. Trouble is, I can't get them to index properly with the old Dura Ace derailleur. Should this be a problem? Are they likely to be incompatible?
