I have a similar problem as well. I have an 8 speed record shifter, 8 speed campag cassette and 8 speed chorus rear mech. I have spent hours trying to get it to shift properly but its still not working. When shifting of bottom gears are perfect (1 to 5), the top gears (6 to 8) are fucked. If I adjust the top to shift perfecty the bottom gets fucked. The rear hanger has been checked by my LBS and it is perfectly alligned. The rear mech is shifting more distance than necessary. Any ideas?
