Hi, just recently came into possession of my dad's old Schwinn Continental and I have been working to make it my daily commuter. So far i disassembled it, cleaned everything, lubricated and packed the bearings, put it back together, replaced the brakes and handgrips, readjusted the derailers, and got the wheels trued. I have been riding it for a week now and I can tell the chain is stretched. I was wondering if anyone could recommend a good chain that would work. It's a 10 speed and I dont know much about chain compatibility. I am trying to stay relatively cheap and just get everything working well.
Also here is a list of other less important issues that I would like some advice on. Some might need to be addressed while others I could live with possibly.
-Tires are very old (they are Sears brand) cracked on sidewalls but ive been riding on them
-rims are a little dinged up (causes some rough braking)
-fork has a little play in it (don't know what to do to fix this)
