Description The Park Tool CC-4.2 Chain Checker is a precision tool designed to quickly and accurately measure chain wear. Using a drop-in, three-point contact system, it assesses a long section of the chain to eliminate guesswork and indicate when replacement is due. Compatible with single-speed and 5 to 13-speed derailleur chains, including modern designs such as SRAM T-Type, SRAM Flattop, Shimano XTR 12-speed, and Campagnolo Ekar 13-speed. Replacing chains at the correct wear interval helps maintain smooth shifting and prevents premature wear of cassettes and chainrings.
