I feel pretty silly asking this, but everywhere I look only offers 8, 9, and 10 speed chains, mine is 7 and I cannot find any "7 speed" chains.
I seem to recall the width of the chain was different between 7 and 8, so I'm assuming I have to get a 7 speed chain but I'd prefer to not get a cheapy from a store. Amazingly my current chain is 10 years old and has thousands of miles on it and it's not stretched at all so it's probably not something I need to immediately replace but since it has so many miles on it I'm thinking it's probably something to think about in the near future.
BTW this is on a 1992 (ish?) Cannondale M400 with Shimano LX/XT mix of components. I had considered replacing the bike this year but I couldn't find another bike that I felt right on, so I've started doing additional maintenane.. Bottom bracket is something I have to tackle too, but anyway.
Appreciate feedback!
