The AA Super is first recorded in the 1984 catalog with the words "NEW" across the picture, making it unlikely that we here are looking at a 1982. Also the serial number sequence of this and the currently only other AA-Super we have recorded are totally out of sequence. To Gazelle nuts like us, this is indeed very interesting!

Above: The good old Campagnolo horizontal drop-outs are here replaced with Gazelle's own vertical short version, a necessity to be able to remove the rear wheel on a frame with such a short wheel base.

Other details of interest on this frame includes the brazed-on cable stops for the derailleurs in the vicinity of the bottom bracket shell. This arrangement is a necessity to deal with the shifter mounts on top of the downtube. All in the name of aero-dynamics which was the big craze in the early/mid eighties.

It might also offer an explanation for the off sequence serial number. At this time most high-end frame builders were switching to cable guides under the BB shell. Then suddenly everything had to be Aero, and those newer Cinelli shells with investment cast guides could not be used.
Scrambling to keep up with the fashions of the time maybe Gazelle had to dig up some older bottom bracket shells for their Aero frames, and these would already be stamped with serial numbers. We know that they batch stamped the shells ahead of time, a process that often explains out of sequence numbers.
