The perfect tool for keeping your bike's drivetrain in tip-top shape. Made with laser-cut precision steel to accurately measure chain wear at levels where chain manufacturers typically recommend chain replacement (0.5% and 0.75%). The tool's three-point design separates pin wear from roller wear, ensuring accurate results. Use the QR code to watch the instructional video. The tool works on all 6-13 speed chains, including SRAM Flattop chains. In general, 11-13 speed chains are not recommended. should be replaced before reaching 0.5% wear, while 6-10 speed chains should be replaced before reaching 0.5% wear. should be replaced before reaching 0.75% wear.
- Checking chain wear is important because a worn chain can cause poor shifting and increased wear on other drive components.
- Made of precision, laser-cut steel.
- Accurately measures chain wear at 0.5% and 0.75% levels - the levels where chain manufacturers most often recommend chain replacement.
- The tool's three-point design separates pin wear from roller wear.
- Includes QR code with instructional video for use.
- Works on all 6-13 speed chains, including SRAM Flattop chains.
