Unior Chain Wear Indicator

How to use the tool:

- A worn chain shifts poorly and causes undue damage to the sprockets.
- The tool is a "go, no go" gauge designed to accurately indicate when a chain is worn out.
- Important! Measurement: from 0 to 0,6% - no chain wear. from 0,7 to 1,2% the chain is worn out and it is necessary to replace it.
