【Usage Indicator】: Hold the derailleur hanger alignment in one hand, keep the body steady, one hand open or push the main body (specifically according to the tail hook), adjust the data deviation of the measurement rod corresponding to the data deviation of the ABCD point is OK, the adjustment process may need more subtract. (Note: ABCD refers to 4 points of the end face of the rim).
【Deviation Measurement】: Rotate the lock handle, adjust the measuring rod, lock the sliding sleeve, adjust the distance between the measuring rod and the ring, determine the value of the measuring rod, measure the deviation between the tail hook and the ring.
【Strong Material】: The derailleur hanger alignment gauge main body is made of aluminum alloy with anodized surface, which reduces the weight while having strong hardness.
【360° Correction】: Rotate the spacing between the wheel group and the tail, 360° rotation measures the spacing between the wheel group and the tail. Lock the rod, accurate thread, closely fit, clockwise rotate the handle, screw the rod into the tail, accurate lock.
