Even if it's bent, it's always in the same position, since it's "fixed".
It has to be a rotating part(s).
hmmm. ok, so i can see that if the axle is bent, it still just sits there, which is exactly whats happening when i look at the hub and axle as the wheel spins: the axle doesn't move. so the hub, if it is straight, will just rotate around that stationary axle and appear stationary as it spins, yes? so the fact that it oscillates means there is an irregularity in, say, a race--maybe something threw it out of round?
could mismatched bearings also cause this? or a skewed cone? really trying to understand the physics here.
thanks!
