As my title says bought a:
Bianchi 1985 vintage in almost mint condition Shimano 600, 12 speed (2x6) with freewheel, friction shifters I'd like to turn it into an index shifter.
Do I just swap out to index shifters Shimano 6 speed? And then get a Shimano SIS rear derailleur, and I'm golden? Are there different sizes I should know about?
Any suggestions? Anything else I should know? I'll be happy if that's "simple". I'll try to tune it up as much as possible if not bring it to a bike shop. I'm very new to modding things and starting to learn and try things myself.
Thanks in advance!
