Chain Gauge Wear Checker 5-12 speed

The Lezyne Chain Gauge Wear Checker is a compact, precision tool that helps riders protect their drivetrain investment by identifying chain wear before it leads to costly component replacement. Made from durable stainless steel, it combines accuracy, simplicity, and multi-function convenience in one easy-to-use piece.

Designed to work with most 8, 9, 10, 11, and 12-speed chains, this gauge measures wear with confidence thanks to tight machining tolerances and clear indicators. It also includes a built-in chain hook for easier maintenance, a valve core remover for quick tire service, and even a bottle opener for post-ride refreshment. The included ring makes it easy to hang near the workbench so it’s always within reach.
