KMC Digital Chain Checker

KMC’s Digital Chain Checker provides an easy and accurate way to keep an eye on chain wear and it is compatible with all chains including 12-speed. A worn chain causes accelerated wear to other, more expensive parts of the drivetrain so replacing it in a timely fashion saves money on cassettes and chainrings whilst also keeping shifting sweet and quiet.
