Schwinn Frame Identification Help Needed
 

This is a 27" frame ten speed. I bought used 16 years ago and am painting it for the second time. Now, however, I am interested in figuring out just what it's pedigree is. All I know is it's really light for it's size and I love it. See pics for the clues. any help is welcome.
Thanks!

Chris.

Sorry, the pics are too small to see well. Serial number is IA11452
There is a small number also on front badge 0191

Is it "IA" or "1A"? If 1A11452, the frame was made and the bike assembled in either January, 1981 or January, 1991. Normally, the decade is determined by the decals on the frame and the components, but that doesn't seem possible because of the repaint and lack of components. The head badge number (0191) indicates the bike was assembled on the 19th day of a year ending in 1; either 1981 or 1991. The fact that the rear dropouts are stamped and not forged says it's not a high end frame.

You can browse the 1981 catalog starting HERE and the 1991 catalog starting HERE.

Here is a better shot of the serial number. I am sure it is IA. Thanks for the reply.

I would say so too, from that picture
