Well, answer me this: When I am in the larger cogs, the chain makes a lot of racket, and when I get into the smaller cogs (straight chainline), the drivetrain is nearly silent. Thing is, the Park go/no-go chain tool tells me the chain isn't even close to worn out. I used to use homebrew chain lube (mineral spirits and used tranny fluid), but was tired of the noise and having to lubricate so often. I bought Prolink and I think it may even be worse than homebrew. After 1 ride, the chain is noisy again.

What gives?
