Chain Wear Indicator RK Chain Note: This seat strut plateChain Wear Indicator for #219 chains. This tool helps you to judge the wear of the chain. It is essential but simple to use. A worn chain heavily increases the consumption of the front and rear sprocket. This tool has two measurements: Side 1) Tells you when you should not use the chain during a race Side 2) Tells you when you should dispose of the chain If the chain does not fit the tool, it means it is still within the ideal operating window.
