The Park Tool CC-4.2 Chain Checker takes the guesswork out of chain maintenance with its precise, laser-cut, drop-in design. Measuring a long section of chain at three contact points, it accurately indicates wear at 0.5%, 0.75%, and 1.0%—the key thresholds for replacement. Compatible with all 5–13-speed derailleur chains (including SRAM® T-Type, SRAM® Flattop™, Shimano® XTR® 12-speed, and Campagnolo® Ekar™ 13-speed) as well as single-speed chains, the CC-4.2 is the reliable tool every mechanic needs to extend drivetrain life.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul style=\"list-style: circle; list-style-position: inside;\"\u003e\n\u003cli\u003eTwo-sprocket (single-speed) chains: replace chain at or just before 1.0%\u003c\/li\u003e\n\u003cli\u003e5-to-10-speed chains: replace chain at or just before 0.75%\u003c\/li\u003e\n\u003cli\u003e11-to-13-speed chains: replace at or just before 0.5%\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e \u003cspan\u003eMany drivetrain manufacturers have unique recommendations specific to their components.
