Find out exactly when to replace your chain with this specialised tool.
Full DescriptionThe Jobsworth chain wear indicator determines if your chain needs to be replaced before any nasty mechanical issues take place. All chains stretch over time, leading to poor shifting, losses in drivetrain efficiency and the increased possibility more serious mechanical issues such as chain snaps. When the chain wear is between 0.75% and 1.0%, you need to replace your chain. If the 0.75% side of the tool fits inside one link of your chain, you need to replace it soon. If the 1.0% side fits in, replace your chain straight away.
