Park Tool Chain Checker (CC-4) colour-dark-grey Their integral ’Extreme Pressure Additives’About Park Tool Chain Checker (CC 4)The CC 4 is a drop in style gauge that measures bicycle chain wear. The laser cut CC 4 accurately measures a long section of chain and strategically comes in contact with the chain in three places, quickly and easily taking the guesswork out of knowing when chain replacement is necessary.
