Hello All

I know this isn't a very old frame. But I have been
looking, for one like it, for a little bit. The only trouble
is the hole in the seat stay. Did some research, but
can't find out what went in that hole, maybe a rack
mounting screw. Does anyone know, and can I replace
what is missing.It's a 2005 Schwinn Super Sports, frame.

on the 2007 Super Sport there's clearly a screw in the same location (looking at a photo online) but I couldn't tell you what it's for...

I'd imagine you'd have more luck in a different room at bf... maybe I'm wrong.
