I have got my Fuso working as a nine speed with Campy Ergo brifters, Shimano 10 speed cassette, Shimano 7400 (six speed) derailleur and a Shiftmate. All is good except the 7400 can't quite reach the biggest cog, giving me a nine speed in effect. I really need that last gear, especially till I lose a little more weight. My lbs owner tells me that a 7402 (eight speed) rear derailleur should get me the extra throw I need to get into the low gear...it will grind away with the 7400 so it doesn' need much. And the 7402 looks almost identical to the 7400 and that would make ME happy. Has anyone here done this successfully with a 7402?
