LASER 8160 LTR Chain Checker Wear Indicator Gauge Bicycle Tool Chrome Moly

This chain wear indicator gauge should be used periodically to measure how much a chain has worn and stretched, ensuring it can then be replaced before it has caused any additional wear to the components that it runs on. A worn chain can be noisy, cause running and gear shifting issues and prematurely wear out sprockets and chain rings which can be costly to replace.

• Checks for chain wear & stretch.
• Features link measurement gauge shown in mm increments & wear checking indicator showing percentage wear.
• Acts as a third hand to hold the two ends of the chain while links are fitted.
• Also includes a thread thickness measurement scale.
• Manufactured from chrome molybdenum.
