Park Tool CC-3.2 Chain Wear Indicator SOFTGOODS 11-28: 11-12-13-14-15-17-19-21-23-25-28A 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.
