Copies of this Document were handed out at the 1987 IHPSC in Washington , DC.

The main points of this invention are: 1) The Trailer does NOT swing side-to-side, but can move up and down, like a Swing Arm, this is better for pushing the Bike, and 2) There are Hangers mounted to the Dropouts, which receive the Trailer Swing Arms, the Device does NOT bolt directly to the Axle Nuts.
