Chain wear indicator Cyclus Tools (720062)

This tool measures the extent of chain wear and helps determine when the chain needs to be replaced. Regularly checking chain wear (stretch) and replacing the chain in good time helps prevent premature wear of other, more expensive drivetrain components, such as cassette sprockets, chainrings and rear derailleur pulleys.
