That's them. The theory I do get.
But is that really real world?- as well as symmetric vibration (things what never change) there are asymmetric ones - like road surfaces. I don't dispute it works - I'm just not 100% sure I understand it all - And I have to at least eliminate my doubts. Also in a single track tyre there are other forces at work. Not saying worse or good / bad, just different.
@cootertwo - Aha - I see. I've only ever seen the slimy green stuff.
