Park Tool CC3C - Chain wear indicator

Simple and easy to use chain wear indicator to help identify worn drive-Chain components

• A worn chain shifts poorly and wears sprockets at an accelerated rate
• The CC-3 is a Go / No-Go gauge designed to accurately indicate when a chain reaches 0.75% and 1% 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
• If the 1% side fits into the chain, the chain is worn out and should be replaced immediately
• 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
