OK, I've finally decided to ask the following question:

Suppose one puts two identical bicycle wheels on the same axle, and sets them at identical rotational velocities, but in opposite directions.

What happens when one tilts or tries to tilt the axle if the axle is a non-bending one?

I make my own. Have a local bike shop BUILD you a 27" or 700c wheel using a BMX hub. You can't bend that axle! Fill the tire with whatever you want. I just use the tire and tube as is and use my old weighted wheel for the rotating stool demos. It's quite simple to weight this, though.

Tappers,

In your opinion, who has the best bicycle wheels with weighted rims for gyroscope/angular momentum demos.

Thanks,
Dale
