If it was the rear cogs/gearing it will likely wear out your new chain very quickly.
It's the first time I've ridden the bike in over 15 years. (Pertinent thread here:

I never replaced the chain when I was originally riding it in the 90's (because I was a kid in middle/high school and didn't know such a thing), and I don't feel like it was ridden enough to wear down the cassette that badly. But, I mean, anything is possible.
This past weekend I put on the new chain, after cleaning the hell out of the entire drivetrain. I did not adjust the cables or the derailleurs though because they still shift perfectly and also I don't know how. The cables need to be replaced since they are original but I'm mostly still shaking the jitters out of the bike before doing too much overhaul.
I will take a few pics of the cassette teeth before I commute home and post them here for y'all to take a look at.
Thanks everyone.
