Yo yo yo everybody.
Went to service an old bottom bracket, and the fixed cup shows very slight "brinelling" (I don't know if that is a word or if it is spelled correctly).
Question is, in general, how much wear is acceptable for you experienced mechanics to reuse a cup? Or is it one of those things that once you see wear it'll deteriorate quickly and warrent a replacement soon anyway.
This is a general question about all bearing surfaces, but for the sake of an example, here's a pic of the cup I took off today. I plan on reinstalling, as it doesn't look too bad to me, and the bike isn't that special.
