Chain Wear Indicator 1644/6

The perfect tool to keep your bicycle's drivetrain in excellent condition. Made from laser-cut precision steel, this indicator accurately measures chain wear at the levels where manufacturers suggest replacement.

Technical Features

• Monitoring chain wear is essential, as a worn chain can lead to poor shifting and wear on other drivetrain components.
• Made from laser-cut precision steel.
• Accurately measures 0.5% and 0.75% chain wear, wear levels at which chain manufacturers commonly recommend replacement.
• The three-point tool design isolates pin wear from roller wear. It features a QR code with video usage instructions.
• Works on all 6 to 13-speed chains, including Sram flat top chains.
• Refer to the chain manufacturer's replacement instructions. General guideline for chain replacement:
• 11 - 13 speed chains - replace at or before 0.5% wear.
• 6 - 10 speed chains - replace at or after 0.75% wear.
