A worn bicycle chain can lead to poor shifting performance and premature wear of drivetrain components, resulting in costly repairs. The Park Tool CC-4 Chain Checker is an essential drop-in style gauge that simplifies chain wear measurement, helping you avoid these issues. Precision-engineered with laser-cut accuracy, the CC-4 measures a long section of the chain and makes contact at three critical points. This design quickly and reliably removes the guesswork from determining when your chain needs replacing.
The CC-4 works seamlessly with any 5 to 13-speed derailleur chain, including SRAM® T-Type, SRAM® Flattop™, Shimano® XTR® 12-speed, and Campagnolo® Ekar™ 13-speed chains. It accurately indicates when your chain reaches 0.5% and 0.75% wear, the thresholds at which most manufacturers recommend replacement.
CC-4 Features:

Replacement Guidelines:
- 5-to-10-speed chains: Replace at or just before 0.75% wear.
- 11, 12, 13-speed chains: Replace at or just before 0.5% wear.
Be sure to consult specific recommendations from your drivetrain manufacturer, as guidelines can vary depending on the components.
