I am finally done rebuilding my '87 Schwinn World Sport. I found it on Craigslist in January for $35, it was in pretty good shape for a 24 year old bike, but needed some work. I replaced the tires, bartape, brake levers and cables, shift cables, and chain. Fully disassembled the bike and re-lubed and greased all moving parts. Polished all the chrome and aluminum and now the bike is rust free. I still have to adjust the deraileurs but other than that the bike is now rideable. I'm stoked with how it turned out, not bad for a bike that was built when I was three years old! Before: After!
