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 bicycle falls on the right side, damage to the rear derailleur and deformation of the derailleur hanger often occur. When performing repair work, first the rear wheel must be centered because an alligned 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 parallelism between the derailleur hanger and the wheel, and to align the hanger if the parallelism is not correct.
	If the bicycle falls on the right side, damage to the rear transmission and deformations of the transmission bracket often occur. This causes the loss of the transmission bracket parallelism, which hinders proper functioning of gears.

	The tool is easy to use and very precise. It is used to check the parallelism between the transmission bracket and the wheel, and to align the bracket if the parallelism is not reached.
	How to use the tool:
	Mount the control to the derailleur hanger. Move the slider along with the measuring gauge towards the wheel rim and position it in such a way that the gauge only lightly touches the wheel rim. Perform the check by moving the tool to different positions on the wheel 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 of the hanger 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 on all positions.
