Hi folks,

My friend borrowed my fg and decided that my chain was too loose for his taste. He pulled the wheel as far back in the dropouts as he could and cinched it down. He did this at the loosest part of the chainwheel's warp, meaning the tight part ended up really tight. It was slightly noisy but nothing crazy. A few days later I noticed that when I tap the chain it makes a little rattle noise as if something has changed. The chain looks like it's in decent shape but I have not checked for stretch. Do you guys think I have a damaged chain?
