Alignment

From WikiPedalia

Adjusting parts so that they are in their proper positions and orientations. On bicycles, this is used mostly with reference to

  • Frames -- so that the centerlines of all the parts of the frame are in the same plane, at a right angle to the centerline of the bottom bracket; the rear dropouts are equally-spaced from the centerline, the correct distance apart to receive the rear hub, and parallel.
  • Front forks -- so that the dropouts are at a right angle to the centerline, parallel, equally-spaced to either side, the correct distance apart to receive the front hub, and with the appropriate distance ahead of the centerline of the steerer tube (rake) to provide good handling. 

For adjustment of the spokes of wheels, the word "truing" is used, rather than "alignment".
