Paramount Track Tandem's were a total custom item for Schwinn. I'm sure they were offered to the racing community at the time "as a service", not because Schwinn made any money on them. They sponsored, built, and raced them in Pan American, and Olympic games. Schwinn built a couple for each Games, raced them, then the tandems found there way to a local "racing Schwinn Dealer". The dealer looked after the bikes, maintained them, and transported them to the local Velodrome track for rider use. I think Jack Disney kept his own Paramount Track tandem? I remember games tandems in white, silver, or kool (opaque) blue colors. There could have been other colors.
Jack and Bobby Kemp owners of North Hollywood, and Bob Hansing owner of Montrose Bike Shop were two local Southern California Schwinn dealers that looked after the Schwinn tandems raced at Encino in Southern California. I'm sure Schwinn planted some of the other Games Tandems over the years at other Schwinn dealers near their local area velodromes. It was a way of Schwinn's grass roots support for bicycle racing.
The Kemp's were hard core bicycle racers. Not only did they run their Schwinn Dealership and Race at Encino, but they were the United States wholesale importer for Mondia and Allegro bicycles. If you have ever seen a bicycle with a smoked paint job, that was a Swiss made Mondia or Allegro. The bikes were a work of art and sold at the price of a Paramount.
Bob Hansing left his dealership in Montrose to be run by Dennis Hansing his son. Bob went on to run Shimano American. He took his bicycle racing and industry experience and developed the Dura Ace product line, that we all loved.
