I will try to express in words what I rode in high school.
10 speed. Probably weighed more than a pig.
Drop bars turned back 180 degrees (think "machine gun." I know I did). That way I could brake by leaning on the brake levers which was good since the suicide levers didn't work.
Cottered cranks that were beyond loose.
Two speed. Front derailleur actually worked. Rear was frozen.
The cogs originally had teeth every other link (I don't know what the thinking was here. Weight? Resistance?) At that, some of them were missing from wear. Between regular chain skipping and the loose cranks, it made a rhythm that reminding me of the base line in "I Want You to Want Me" by Cheap Trick.
Tires actually had "see through" spots. Thorn resistant tubes must have been very high quality back then. Besides, when I did get flats it got me out of first periiod English taught by a priest who would greet us by telling us to "drop dead."
And finally, when the back wheel became seriously warped I just loosened the brake bolt so that the brake swung back and forth with the wheel.
This bike, however, is no match in terms of crapicity compared to what I started driving the following year after I turned 16.
The last I remember of this bike was that I took it to Travis AFB with me when I got stationed there. I think I rode it once and left it behind the barracks. A friend of mine who was a very non-cyclist borrowed it once and said he almost abandoned it because he thought walking would be less effort.
