okay first let me say that this is my chain. i bought this 85? miyata 310 off a guy who said it had been in his garage for the past couple years, but it was ~$1200 new (can't remember exact amount). anyways here are some pics of the chain, freshly cleaned chainrings, and dirty freewheel:
wait, before you post that my chain is toast, in general how can one remove rust from an old chain?
