Also i had a rear hub which used a large flange hub, snap taking 2 or 3 spokes out with it, a long walk home that day.
There was also the dodgy bottom bkt, with no taper, that the cranks would come off, and not tighten up.
The Bottom bkt also had circlips as far as i can rremember to stop you getting the thing out, and the seat tube was a s trange size, mine i had to screw a screw through the frame, to hold the pillar in position.
Finally the front wheel crossed over the toe clips when going round a corner, you soon got used to this as you fell of otherwise.
