Well I realized the noise is coming from the cylinder shaped things that looks like it helps guide the chain around in its path, it is a perfect cylinder up until one point it looks like my chain took a bite out of a part of it (it is like perfectly shaped to my chain so it looks like it took a perfect bite out of it) Does this mean I need to replace my roller or is it supposed to be like that? I can really use some help because that noise comign from the chain bothers me, it's not too noticable when I'm past second gear but I does bother me knowing it is there.
