Thanks for the reply. The chain is a KMC stainless steel chain from 2008 - factory original on Downtube Mini. I checked all the links and didn't see any that look different from any other - I'm not sure what exactly to look for - I was looking for a link with a higher profile, or perhaps some cutouts or a spring clip. Didn't see anything. Of course, the chain is kinda grungy (which is why I want to remove it in the first place...) I could take a few pictures of it if that would help.
