Well... I hate to be pedantic about semantics, but words is all we've got here.
I think it's helpful if we agree that "Shimmy" is what Jobst describes - specific oscillation of the front end of the bicycle - "the lateral oscillation of the head tube about the road contact point of the front wheel" which causes spontaneous steering oscillation of the front wheel. There are certainly enough variables in the motion of the bicycle that causes shudders - having a wheel out of round will cause it to oscillate, and out of true causes side-to-side vibration. These tend to be speed-specific, but are different phenomena than what is being discussed here. - J -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
