I just bought one of these two days ago, I got it for $75 through Craigslist, it needs tires and that's it...traced it down to a 1986, it's hard tracking the years on these things though, I finally scoured through the Centurion serial number database here on the forums to get that info. Mine has the Shimano "Light Action" RD and Sugino VP crank, double butted tubing, (mine says " made in Taiwan...lower end model for sure but the price was very good for my location.

here's a cell pic as it looks as bought.
