Hi
I had a few terrifying ones...
Universal 26" mtb thing - crank bolt, 14mm socket on one end, the shank of the bolt was smooth - no threads on it at all! Someone had put it in in the factory, then put the crank cap on the end. They must have noticed...
Moore Large full susser - tyre bottomed out on the back of the seat tube
I'll try to think of some more...
