The World Sports were the bottom of Schwinn's road line. Better than a Varsity or Collegiate, but nothing like a Prelude or Paramount.
I received an '85 WS as a high school graduation present from my parents and rode it all through college and law school. Even did a few triathlons on it. It got stolen one night in the mid-90s when I drunkenly forgot to lock it up during a barhopping excursion.
I'd love to have that bike back but mostly from sentimentality. They're not worth much as a serious road bike. On the other hand, they make great beaters, especially as a SS or FG.
