Yeah, it's a biopace crankset, but it's bent...

And I don't mean in a good way. I was really kinda upset about that - I wanted to see what the fuss was about!
Anyway, I've got the thing half apart - it's all coming apart really nicely, and the frame looks super solid. Kinda wish the top tube was prettier, but it doesn't look too bad. I'm wiping it down with vinegar as I go, and it's making everything shine up really nicely.
