The Unior 1-1.2 mm Chain Gauge is designed for accurately measuring chain wear. Place the gauge’s rolling head in the starting position (position 0), insert the measuring jaws between the chain links, and with a slight turn of the rolling head, check the chain’s stretch.
Read the chain stretch—or wear—on the measuring head’s scale, which ranges from 0 to 1.2 mm. The gauge is designed to measure the length of 10 links; repeat the process on different sections of the chain. Manufacturers recommend replacing the chain when the stretch—or wear—exceeds 0.5 or 0.6 mm in a 10-link section.
