So, on my early 70's Collegiate I'm trying to find information on the gear system. I see the derailer is a Schwinn GT 100, how long did Schwinn use this setup and is it at all rare? I'm wanting to find a NOS derailer if possible because mine is rather beat up, anyone have an idea of what one may cost? The current one works just fine, but is ugly as hell and beat up looking!
Is it worth searching for a GT 100 derailer or is there something more readily availible from the current time period? I'm looking to make the bike look as stock as possible, but if I cannot find NOS stock parts I will make due with items I can find.
