I purchased this 1973 P10-9 Schwinn Paramount in July 1998 at a Yard Sale in West Lafayette Indiana. I am the second owner. 24" frame size (61cm) . This is a never restored pristine condition bike, one of my favorite riders. Since this image, it now has a Selle An-Atomica Titanico X saddle. I rode it about 500 very careful miles this past summer..
