18 speeds, top tube shifters, 25 pounds (without the chain/lock), san marco leather seat (might help date it)

does the tubing sticker say "Tenax"?

close-ups would help. post in the c&v forum for definite answers, but from what i can make out it looks a lot like my 1980's schwinn world. are the rear dropouts stamped or forged (thin metal or thick?) seat is not stock- schwinns from that era all said "schwinn approved". how many speeds? it should be a 12 speed, not an 18 speed. there is no way that has a triple up front, and even less chance its a 9 speed rear. if it is a world, it should say it right under where your chain is wrapped, in dark blue with white stripes behind that.

You're right about the speeds, there are only 12. says tanax on the frame. I couldnt find a model name on it anywhere. Dropouts are stamped.

mid to late 80's, possibly a Traveler or LeTour. Tenax was used on their mid to lower lines during this time. Possibly built at the Mississippi plant as was the Schwinn Passage touring bike I had for a while. I'm going to move this thread to the C&V section where we may get more suggestions and ideas.

ill get some better pictures up today, too.
