A worn chain shifts poorly and wears sprockets at an accelerated rate. Park Tool's Chain-Wear Indicator is a “go-no go” gauge designed to accurately indicate when a chain reaches .5% and .75%, the points at which most chain manufacturers suggest replacement. The updated CC-3.2 is longer, more accurate and features permanent measurement markings.

  • 5-to-10-speed chains: replace chain at or just before 0.75%
  • 11-to-12-speed chains*: replace at or just before 0.5%
  • Check with manufacturer for specific replacement instructions
  • *Use the CC-4 for SRAM® Flattop™ and SRAM® T-Type 12-speed chains.
