The scale is laser-engraved for high visual clarity.Positioning Rotating RodThe positioning rotating rod is manufactured using centerless grinding, ensuring high standards of roundness, tolerance, and concentricity. This significantly enhances axial stability and measurement accuracy during rotation.Slider Measuring StrokeSlider measuring stroke of approx. 270 mm360° Rotational AlignmentRotate the handle to lock the derailleur hanger. Using the rotating rod as the axis, perform a 360° rotation to measure the distance between the rim and the derailleur hanger, then calibrate the hanger.
