I have a 1986 Schwinn Prelude road bike also (black),bought it new then. You must have a lot flat land around there.It's very hilly here and being that my legs are are over 20 years older then when I bought the Prelude it would be hard for me to get up some of the hills here.
The Prelude is a nice light bike and I always liked riding it on select roads.It's currently my 3rd back up bike,haven't rode for I don't know how many years.
