A worn chain derails and accelerates link degradation. The chain wear indicator UNIOR chain wear indicator gives a precise indication of whether the chain is worn or not.
Made from laser-cut steel, it guarantees highly accurate measurement.
Measurement: 0 to 0.6 mm - no chain wear. From 0.7 to 1.2 mm of worn chain, replacement is necessary.
