Wow. Thanks so much, cb400bill, for finding that info. Also, thanks to TheDL for the link to the catalogue. I was able to find a photo of my exact bike in the 1984 catalogue (under the Sport 10FF in Sunrise Red, except mine is in the womens style).
Does anyone happen to know what T-Mar means about "The 1984 model had a plain gauge main triangle made of hi-tensile steel." I don't really know anything at all about bikes so this is sort of a foreign language Also what are "stays?" Lastly, I have no idea what any of this means: "The crankset should be a swaged, cotterless design with what appears to be steel chainrings. Derailleurs are respectable SunTour Seven with stem shifters. Brakes should be Dia-Compe 730 or Shimano Z-series side-pull with safety levers." If anyone could help me out I would appreciate it.
Oh, also from what I can tell, Shimano's Front Freewheel system makes it so you can shift gears while you're coasting, not just while your pedaling. Is that right and is that the only significance? Pretty cool.
Thanks!
