Product Description

Park Tool CC-3.2 Bicycle Chain Checker in use

Park Tool CC-3.2 Bicycle Chain Checker

A worn bicycle chain can cause poor shifting and in time can even cause excessive wear to the derailleur and rear cogs, causing a much more expensive problem. That's why bike component manufacturers recommend chain replacement at regular wear intervals. The Park Tool CC-3.2 is a go/no-go gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear (or "stretch"), the points at which most chain manufacturers suggest replacement. The CC-3.2 is long, accurate and features permanent measurement markings. The CC-3.2 works on most derailleur chains* from 5 to 12-speed. For 5-to-10-speed chains, replace chain just as the gauge fits the 0.75% side fits flat into the chain. For 11 and 12-speed chain, replace as the 0.5% side fits. Check with manufacturer for specific replacement instructions.

*NOTE: For SRAM AXS 12-speed road chains, use the Park Tool CC-4.
