A worn chain shifts poorly & 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% & 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
