I'm such a bike noob, I feel like I should know the answer... but I don't.
I noticed a while back that one gold side of the master link was bent out a bit more than the others. I'm not sure if that's normal, but now looking at it today I noticed that the other gold side has a gap in it now. I'm not sure if this is normal, but I figured I'd ask.
Sorry for the dumb question. I just figured I'd ask and learn while doing so.
