A worn chain shifts poorly and wears sprockets at an accelerated rate, the CC-3.2 is a Go / No-Go gauge is 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
  • 10-speed compatible
  • Made in the USA and covered by Park Tool's legendary limited lifetime warranty
  • Product Code: P5324369
