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.
