RonnieP,

The font will help to tell the age, but it sounds like 85-86 era, with those rims.
That was a really nice all-around bike, and raced by lots of folks.

If the font is the blockier CENTURION with some contrast shading on one edge of the letter, it's 85 or earlier, most likely. If the font is thinner with decreasing thickness (increasing thinness?) as the word progresses, it's probably 85 or newer. As the years go up from '85, the decals tend to get a little "busy."

You should be able to swap the Deore LX triple crankset (include the BB) for a nice Shimano double, in 600EX or 105, with BB.

Welcome to the forum, and we're glad to have you on board. Especially with that bike.
