- Keeping chain wear under control is important, as a worn chain can cause poor shifting and wear on other drivetrain components.
- Made from precision laser-cut steel.
- Accurately measures 0.5% and 0.75% chain wear, the wear levels at which chain manufacturers most commonly suggest chain replacement.
- The three-point tool design isolates pin wear from roller wear. Features a QR code with video instructions.
- Works on all 6 to 13-speed chains, including Sram flat top chains (excluding 13v Campagnolo).
- Consult the chain manufacturer's replacement instructions. General rule for chain replacement.
- 11 - 13 speed chains - replace at or before 0.5% wear
- 6 - 10 speed chains - replace at or before 0.75% wear.
The perfect tool to keep your bicycle's drivetrain in excellent condition. Made from precision laser-cut steel, this gauge accurately measures chain wear at the levels manufacturers suggest.
