A wheel which is balanced before tire and inner tube assembly only helps a little, because the disigners cannot possibly know what kind of valve will be assembled, and valves differ in weight. The mass distrìbution in tires (and to a lesser extent in tubes) is always uneven, sometimes just a little, sometimes more.
I try different angular positions of the tire before putting pressure in it, until I find the position that offer the best static balance.
This cannot be done with tubulars or tubes.
Dynamic spin balancing?

Speed wobble (a.k.a. shimmy) can be because of an unalingned fork like described by Craig Calfee here: http://velonews.com/tech/report/articles/9786.0.html
Yeah tried that last year ... the fork is within the 1mm ...i'm pretty sure it was .6
altought the caliber i was using wasn't the best ... the article also states after 30mph it should wobble ... at 40 no probs ... only when i hit 50 plus esp down bear mountain (the road is not the best starting from the top)
