A friend emailed me about a bike called an "SST Jumper". He never sends me photos, but his description was "80's BMX all original appearing, needs tires, and a good cleanup as there is some surface rust on the welds, Plastic KKT pedals , steel freewheel rims with heavy spokes, one piece crank with 5 point spider and removeable sprocket, yellow plastic seat with some name starting with a K". Anyone hear of such a thing?
