Unior Chain Wear Indicator

The perfect tool to keep your bike's drivetrain in top condition. Made from precision, laser-cut steel, this indicator precisely measures chain wear at levels where chain manufacturers commonly suggest replacing the chain (0.5% and 0.75%). The three-point tool design isolates pin wear from roller wear, ensuring accurate results. Use the QR code to watch the instruction video. It works on all 6-13 speed chains, including SRAM flat top chains. As a general rule, 11-13 speed chains should be replaced before or at 0.5% wear, while 6-10 speed chains should be replaced before or at 0.75% wear.

Features
Staying on top of chain wear is important as a worn chain can cause poor shifting and wear out other drivetrain components.
