Abstract (en)
[origin: EP0062158A2] 1. Method of aligning soldered and/or welded bicycle frames by firmly clamping the bottom bracket bearings (the pivot axis) of the frame and adjustably clamping the seat tube in an aligning apparatus and by aligning it into the reference plane which runs perpendicularly to the axis of the bottom bracket bearing and bisects it, characterised in that the angle between the axis of the bottom bracket bearing (the pivot axis) and the axis of the seat tube is measured, the seat tube is mechanically pre-aligned beyond the apparent limit of elasticity in both angular directions, the angle is measured again and the seat tube is mechanically aligned into the reference plane as a function of this angle.
