Default Re: Does this chain need replacing?

Surface rust isn't an issue, it may look unsightly but it won't be a problem for the chains operation. What is more important is that the O rings remain well lubed so that they can do their job of keeping the water and crap out of the bits that actually do the work. Lift the back wheel off the ground (get someone to pull it up on the side stand for you) and spin the back wheel. If the chain runs freely without any tight spots it's probably fine.
