UNIOR Chain Gauge 1644/2

How to use the device:

Made of precisely laser-cut steel

A worn chain causes shifting to be more difficult and causes sprockets to wear out more quickly. This tool allows you to check chain wear by determining whether it's "good" or "bad."

Important !

Measurement: 0 to 0.6% - the chain is not worn. 0.7 to 1.2% - the chain is worn and needs to be replaced.
