Pars I was considering learning how to do this stuff... I mean, if it was a situation where I had been doing it all my life, or at least as a kid, I would do it. I've always done minor repairs on it. But nothing like this. I saw a YouTube about greasing the hubs, and I don't live near a bike co-op that I know of, so I would have to buy the tools. I know this is probably sacrilege in a forum like this, but I'm going to have the bike gone over professionally. Found this service that comes to your house and does it: Velofix. I chose the package where they basically disassemble and inspect and service the entire bike in a day. I have an appointment for this Saturday AM. I'm going to have them put on a new chain, replace any worn parts and fit it to me. I'm going to hold off on replacing the derailleurs until I can see how they are after they've been serviced. They are plastic Simplex, but I don't see any cracks and the cogs look good.
