Back in '90 I bought a Schwinn 754. Total piece of crap. The rear wheel had to be warrantied. Even broke spokes on the front wheel.. The seatpost had an internal quill that was not up to the task, at least for someone of my weight at the time (6' 2", about 180). The post would slide down a bit. Was in law school at the time. Took the bike home for the summer and brought it back to school on Amtrak. Went back later to ride it home from the train station. I can still visualize me climbing a long hill in Pittsburgh heading for my apartment and hearing intermittent pings. Discovered later that those pings were bearings falling out of the freewheel and hitting the aluminum frame. Seriously?
