Hah! When I was about 17 years old I retired my Schwinn Varsity and ordered my first high end bike ... a Schwinn Paramount! My local Schwinn dealer said, "Boys your age usually ride a 23" frame" and he ordered one. I was (and still am) about 5'6". I rode the bike maybe two years with the seat as low as it would go right down on the top tube. I sold it to a buddy.
