    Absolutely fascinating. How can something so simple and common be so mysterious?

    I'm also interested in what bike builders might want to do with the knowledge that they don't need to have the wheel touching the ground behind the steering axis. What advantages/disadvantages could that have?

    You have to have a caster angle,either positive or negative,for the bicycle to stay upright.If you have a zero caster angle,the bike will not right itself.

    If you look closely at bicycles like they use in the circus or do tricks on,they will have zero caster,so that your body weight doesn't effect the steering.

    The more caster(trail on a bike)positive or negative,the more the steering wants to return to center.
