Recently replaced the cables on this old road bike. When indexing the cable I notice how compressed this derailleur is and the two cogs are almost touching - it certainly doesn't look right to my untrained eye and when compared to my modern bike, but the bike is shifting nice and smoothly after much messing around. Is this something I should correct or be wary of?
Inherited this old bike and I'm trying to improve my bike mechanic skills, so any explanations or advice is immensely appreciated.
Thanks
