Chain Wear Indicator
Made from precision, laser cut steel 
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. 
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.
