- A worn bicycle chain causes poor shifting performance and accelerated wear on drivetrain components, causing more expensive problems
- The Park Tool CC-4.2 Chain Checker is a drop-in style gauge that measures bicycle chain wear
- The laser-cut CC-4.2 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 determining when chain replacement is necessary
- The tool works on any 5 to 13-speed derailleur chain (including SRAM® T-Type, SRAM® Flattop™, Shimano® XTR® 12-speed, and Campagnolo® Ekar™ 13-speed chains) or single-speed chain, and is designed to accurately indicate when a chain reaches 0.5%, 0.75%, and 1.0% wear, the points at which most chain manufacturers suggest replacement
- Some drivetrain manufacturers have unique recommendations specific to their components, always double-check to be sure
- Made in the USA and covered by Park Tool's legendary limited lifetime warranty
