I forgot about this post then rediscovered it looking for something else. Better late than never, I guess.
@zandoval It's a Sears Free Spirit, but it has a one piece crank. The range was pretty wide with a few of their top bikes getting aluminum and a few with Campy components. My bike has center-pull brakes and a Shimano Eagle derailleur with its monster guard on the back. Overall they're somewhat better than most of the sewer pipe bikes coming out of department stores at the time.
