Hello Welcome to the forums. Better pics are needed as well as perhaps some information on the parts. I am pretty sure this is an '87 because of the style and location of the Colorado Springs decal. What I am having trouble with is a Sport SX or Premio. That cable for the front derailleur has me leaning towards a Premio.
