Park Tool CC-3.2 Chain Checker Tool Wear Indicator in Silver

A worn chain shifts poorly and wears sprockets at an accelerated rate.The Park Tool's CC-3.2 is a go/no-go gauge designed to accurately indicate when a chain reaches .5% and .75% "stretch," the points at which most chain manufacturers suggest replacement.

• 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
• 10-speed compatible
