I've got a 2001ish Schwinn Suburban that I'd like to find a spec sheet for so I can figure out what sizes things are to decide if it's worth upgrading (if parts are still common enough) BB looks pretty small for instance. But bikepedia doesn't list the suburban. I know, it's an x-mart high-ten frame, but it's been plenty sturdy, and it's a lot easier for me to sneak an upgrade every month or so in than to come home with a new bicycle.

It'd also be nice to have the specs sheet so I can determine sizes of tools to buy to work on the bike.
