Park Tool Chain Checker / Chain Wear Indicator MTB / Road Bike – CC-3.2

Park Tool Chain Checker / Chain Wear Indicator suitable for a MTB or Road Bike

A worn chain shifts poorly and wears sprockets at an accelerated rate
The CC-3.2 is a Go / No-Go gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear – the point at which most chain manufacturers suggest replacement
The chain should be replaced soon if the 0.75% side fits into the chain, before other drive train components also start to wear out fast
Longer design measures a greater length of chain, giving greater accuracy
Made from precision, laser cut steel
Consider that if you replace a chain because of wear other vital drive-chain components may need to be renewed too
10-speed compatible
Made in the USA and covered by Park’s legendary limited lifetime warranty
