Schwinn Paramount tandem track bicycle (c.1956; Chicago) I'm told this is a U.S. Olympic Team bike, equipped at John's in Pasadena. Several tandem sprint national titles have been won on it. Black finish, filet-brazed marathon-braced chrome molybdenum frameset, Campagnolo Record headset, bottom brackets & cranksets with inch-pitch chainrings, BH Airlite high-flange hubs, Super Champion Arc-en-ciel rims, Clement tires.
