Except that the Dura-Ace 7400 rear derailleur has a unique cable pull/throw with respect to other Shimano 8-speed derailleurs. So when you use the 9-speed shifters, you get the correct spacing for an 8-speed cassette WHEN you use a DA7400 RD. Look up instructions for the BS-77 bar end shifters. They also come with a sticker that explains this.
