I have a circa 1994 mountain bike with Shimano alivio components
the rear gear shifter no longer works. I took it apart and put it back together but did not get it to work. I wanted to get a replacement shifter. so I was wondering :
will any shimano 7 spd index shifter work properly with the existing Shimano alivio 7 spd rear derailleur and rear cogs that the bike came with? will another brand 7 spd index shifter work?
