1. Welcome to the forums, and to C&V, in particular.
2. Not too much disdain for folks around here, regardless of what their bike's frame material is, we are equal opportunity here.
3. Scooper, of one of the other Schwinn guys, will be along and they can tell you more details about your bike that you wanted to read.
4. Very nice bike, that looks pristine.
One note, take pictures from the drive side, and get the components as much as possible.
Welcome aboard!
Bill
