Abstract
A bicycle frame aligning device holds the extremities of the frame at a fixed reference height above a reference plane. The bottom bracket shell is clamped to a mounting shaft pivoted between the shell and the reference plane, so that misalignment of the bicycle frame causes the shaft to tilt from perpendicular to the reference plane. Integral gauges referencing the shaft display the misalignment. The same gauges also display the deflection applied to align the frame to align it. The frame displacements needed to align the frame are applied with a crank attached to a high efficiency jacking screw. The combination of the crank action and integral gauges allows precise incremental alignment effort to be applied, thus making the alignment process more efficient and reducing the chance of buckling the bicycle frame.
