I have an old Cannondale that I still ride 4-5 times per week. I was just wondering how old it is. I've had it since new but can't remember the year I bought it. It has the rear drop-out that is one piece, derailleur hanger is integral to the drop-out. I remember Cannodale had a promotion to bring in any bike frame and you would get the Cannondale for a very good discount.
