Bike Chain Checker for Cyclists

The Park Tool CC-2 Bicycle Chain Checker is a valuable tool designed to help cyclists accurately determine the wear or "stretch" of their bike chains. A worn bicycle chain can lead to poor shifting and accelerated wear on the derailleur and rear cogs, potentially resulting in a more costly repair down the line. That's why component manufacturers recommend replacing chains at regular intervals.

The CC-2 allows users to quickly and precisely assess the condition of their chain. Simply insert the tool's pins into two links, lightly press the swing arm gauge, and then check the gauge window for an accurate reading. This user-friendly design makes it easy for cyclists of all skill levels to maintain their bicycles effectively.

The CC-2 is compatible with a wide range of chain types, including single-speed and derailleur chains, as well as Shimano XTR 12-speed chains. For SRAM AXS 12-speed road chains, the Park Tool CC-4 is the recommended tool.

As a general guideline, 5-to-10-speed chains should be replaced at or just before the 0.75% wear reading, while 11-to-12-speed chains should be replaced at or above 0.5% wear. For single-speed chains, the recommended replacement point is at or above 1% wear. However, it's always best to consult the manufacturer's specific instructions.
