• 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.
