Derailleur hanger alignment tool - 1602/2


  • Material: special tool steel, the pipe is made of construction steel
  • The derailleur hanger and the rear derailleur, must be parallel to the rear wheel which enables smooth running of the chain and fast and efficient shifting.
  • If the bicycle falls on the right side, damage to the rear derailleur and derailleur hanger often occurs. The result of this damage causes misshifting in the rear derailleur. When performing repair work, first the rear wheel must be centered because an aligned rear wheel is the basis for the adjustment of the derailleur hanger. The tool is easy to use and very precise. It is used to check the alignment of the rear derailleur hanger and the wheel, and to align the hanger if necessary.

How to use the tool:
  • Mount the control to the derailleur hanger. Move the slider along with the measuring gauge towards the rim and position it in such a way that the gauge only lightly touches the rim. Perform the check by moving the tool to different positions on the rim. If the derailleur hanger is parallel to the wheel, the measuring gauge will keep the same distance from the rim on all positions. If distance between the measuring gauge and rim changes in any direction, the hanger has to be aligned. Repeat the procedure until the distance of the gauge and the rim is the same in all positions.

Occasionally, without notice, manufacturers change product design and/or specifications.
