- 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

Essential for SRAM 12 speed chains
"easy to use and the best way of checking SRAM 12 speed chains - and cheaper than the SRAM tool!"
Perfect chain checker
"This is the perfect tool for checking my SRAM type-t gx eagle chain. I know SRAM recommend changing the whole system but if I can get away with checking the chain and changing this out I'm hoping to get at least 2 chains per cassette. This tool provides accurate readings for the eagle gx type-t chain. Excellent service and speedy delivery from bike parts. co. uk"

"As described hood quality chain tool."
Easy to Use Chain Checker
"The newer three pronged style of chain checker, more accurately measures wear than the old two prong type. Essential to minimise wear on expensive 12 & 13 speed groupsets."
