Okay so I've broken down the bike components to the frame, stripped the paint, and am ready to order parts. The only thing: I have no f**ing idea where to begin! The paint process I have covered, but as far as wheels, bottom bracket, hubs... I have no idea where to go next. How do I find out if a bb is compatible with my bike? Its an older Schwinn World Traveler by the way. I think Japanese made. How big of tires/rims do I get? Do I get the hubs / spokes / rims separate? Please drop knowledge... I need it!
