Alas, pics will not be forthcoming; it's in Wisconsin, and I'm in Northern Virginia. I found a few pictures of me riding it in a century (about ten years ago), but they only show the bike from head-on and would provide no useful information to anyone.

That said, I went back and looked at the catalogs that someone kindly posted above (they are the same ones I had looked at earlier).

On closer examination, the Sky Runner piqued my interest -- but the "Runner" decal is in a different location (the back of the top tube instead of the front on the Sky Runner) and the font is completely different (block letters instead of the script shown on the Sky Runner). Also the Sky Runner doesn't have braze-ons for downtube shifters, which mine has. Mine also has side-pull brakes and the fork has no canti-posts (although the fork could have been swapped out).

Looking closely at this page http://4.bp.blogspot.com/_whtVpXkKwl...0-h/img110.jpg however, makes me think it's a 1986 Omnium with components swapped out. The frame shown in the background looks exactly like mine (ugly welds, white frame, little hole on the inside of the headtube) -- only the graphics and color scheme is all wrong (mine has the red decals, a silver stem with white handlebar tape, white brakehoods, and red cable housings).

I think I have the right frame, but nothing else seems to add up. Guess my bike will remain a bit of a mystery.

Thanks for the help!
