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.
