I recently picked up a 1985 Schwinn Le Tour with Suntour ARX GT components. The rear derailleur is a 6 speed and has friction downtube shifters. Is it possible to add 6 speed Suntour Accushift downtube shifters to be able to have the index capability, or am I SOL?
I have received conflicting information, because some sites say that the rear derailleur is not index compatible, whereas one site stated it was compatible. I thought the index function is all in the shifter and not in the derailleur itself? Thanks for your help.
