I have a KMC X10SL with about 2500 'hard' miles on it; training and racing.
I generally use wax lube; it's usually very quiet. I have done major cleaning on it before with dish soap and a toothbrush, and it's been generally fine.

Recently i used a spray degreaser (same company as the wax lube) and it got the chain amazingly clean very fast. so i wiped it off, applied new lube, let it dry, and applied new lube again. twice.

the chain has since become extremely loud. the RD is adjusted properly.
I feel that i have re-lubed it enough now that it really shouldn't be a lube problem. it's still very clean.

i searched and read that degreasing a worn chain will loosen the grit in the links and kind of "expose" how worn it really is.

what do you think? a sign the chain is done for?
