The KMC Digital Chain Checker is a tool designed for cyclists who value reliability and the health of their equipment. By precisely measuring chain wear, down to one-hundredth of a millimeter, you can accurately determine when to replace your chain, avoiding both premature and delayed intervention. Measuring in inches or millimeters allows the tool to adapt to your needs, and its compatibility with all chain types, including 12-speed, ensures versatility in every situation. This will help you avoid unnecessary drivetrain wear while saving on service and replacement costs. The durable metal construction with a large, easy-to-read LCD display combines modern design and practicality, satisfying the needs of both amateurs and professionals. The device is ready to use right out of the box – it comes with two CR2032 batteries. Its luxurious craftsmanship and elegant appearance also make it a perfect gift for any bike enthusiast, combining exceptional functionality and style.
