<p>PORTABLE WHEEL TRUING GAUGE A pair of parallely spaced apart arms are pivotally attached to a plate member which can be attached to the fork crown of a bicycle. A rim contacting head is threadedly attached to the arms. The head is used to gauge both the roundness of the bicycle wheel and the deviation from the plane of its axis or degree of "wobble". The gauge maintains the references of the "roundness" and "wobble" while the wheel is taken in and out of the forks to tighten the wheel nipples and thereby correct the wobbles and out of truness of the wheel.</p> |
