The CC-4 is a drop-in style gauge that measures bicycle chain wear.The laser cut CC-4 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 knowing when chain replacement is necessary.A worn chain will cause poor shifting as well as accelerate drivetrain wear.The CC-4 works on any 5 to 12-speed derailleur chain (including SRAM AXS) and is designed to accurately indicate when a chain reaches .5% and .75% wear, the points at which most chain manufacturers suggest replacement.Made in the USA and covered by Park Tool's legendary limited lifetime warranty.
