PARK TOOL CC-3.2 Chain Checker Gift card so there’s total retention evenA 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.
