i just have a really worn big ring on a bike that i would usually just replace, but its weird 122 bcd is difficult to find on the cheap. i know a newer ring would help the upshift from small to big ring, but didn't know if making these rounded teeth 'sharper' (more defined) would help. taller, would definitely help, but i can't do that without a time machine.
removing the little hook that forms on the back side of each tooth and letting a new chain settle properly on the worn cog rather than hanging up on the hook and then skipping.
interesting. i also haven't tried a new chain. it's a flip bike i completely overhauled, but i'm trying to keep all costs down.
