Description
Precisely gauge the wear of your chain and replace it at exactly the right time. Park Tool's CC-2 Chain Checker offers a fantastic way to determine chain wear and stretch. This can determine how much life a chain has left or if it is in need of replacement. Simply insert the Chain Checker's pins into two links, press the swing arm gauge tight, and then check the gauge window for an accurate reading.
The CC-2 is compatible with all speed chains used with derailleur systems. For 9 and 10-speed chains, replace chain at or just before the 0.75% readings. For 11 and 12-speed chain, replace at or just before the 0.5% reading. Always follow manufacturer instructions for specific chain replacement instructions.
