Park Tool CC-3.2 - Chain Wear Indicator

  • A worn chain shifts poorly and wears sprockets at an accelerated rate
  • The CC-3.2 is a Go/No-Go gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear - the point at which most chain manufacturers suggest replacement
  • The chain should be replaced soon if the 0.75% side fits into the chain, before other drive train components also start to wear out fast
  • Longer design measures a greater length of chain, giving greater accuracy
  • Made from precision, laser cut steel
  • Consider that if you replace a chain because of wear other vital drive-chain components may need to be renewed too
  • Made in the USA and covered by Park Tool's legendary limited lifetime warranty
A worn bicycle chain can cause poor shifting and in time can even cause excessive wear to the derailleur and rear cogs, causing a much more expensive problem.

That's why bike component manufacturers recommend chain replacement at regular wear intervals. The Park Tool CC-3.2 is a go/no-go gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear (or "stretch"), the points at which most chain manufacturers suggest replacement. The CC-3.2 is long, accurate, and features permanent measurement markings. The CC-3.2 works on most derailleur chains* from 5 to 12-speed.
  • 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.
