How old is your bike?

[Heifzilla]

Oooh! A twin or near twin of my 1985 World Sport!

According to Schwinn catalogs I found online, the World Sport came in "Charcoal" in both '85 and '86. It looks like the way tell the year is by the components: 85's have an SR crank and Sun Tour shifters/derailleurs while 86's have a Sugino crank and Shimano shifters/derailleurs.

I'm rebuilding mine for indoor trainer use. It is getting all new components - only the frame, fork, and seat binder bolt are getting reused. I don't quite know what to do with the original components...

Ah, so that's how you know which year. DH wasn't sure, he was "15 or 16" when he got it and couldn't recall for sure. His bike is pulled up on the rack in the garage and I don't feel like pulling it down to see what he has right now. He changed out the handlebars & rims, but I think everything else is original. When I look online I don't see many charcoal ones, so it's cool that you have one...is some of your lettering pink? The charcoal ones I have seen have yellow lettering. DH's is pink and white. He says he's manly enough that a little pink doesn't bother him, lol.
