Abstract: The apparatus of the present invention includes a body that may be attached by straps to a structural member of a vehicle having a spoked wheel. The body carries an indicator that may be moved relative to the body. The indicator extends towards the rim of the bicycle to indicate the position of the rim with respect to the structural member of the bicycle. The indicator shows areas of the rim that are not true and which require adjustment. The tension of corresponding spokes can then be adjusted to bring the wheel into "true". Also included in the present invention is a method of truing a bicycle wheel including the steps of fastening the system to a structural member of the bicycle, aligning the indicator with the rim of a wheel, adjusting the indicator to contact the rim of the wheel, rotating the wheel to determine contact points between the rim and the indicator and adjusting the spoke tension to achieve uniform contact between the rim and the indicator.
