The Park Tool CC-4 Chain Checker 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 i n contact with the chain in three places, quickly and easily taking the guesswork out of determining when chain replacement is necessary. The tool works on any 5 to 12-speed derailleur chain (including SRAM T-Type, SRAM Flattop, and Shimano XTR 12-speed chains) and is designed to accurately indicate when a chain reaches 0.5% and 0.75% wear, the points at which most chain manufacturers suggest replacement. 5-to-10-speed chains: replace chain at or just before 0.75% 11-to-12-speed chains: replace at or just before 0.5% Check with manufacturer for specific replacement instructions Show more
