Prevent poor shifting and uneven drivetrain wear by replacing your chain before the rear cog becomes worn. The Park Tool Chain Checker CC-2 allows you to quickly and accurately measure chain wear and stretch, ensuring optimal performance and prolonging the life of your drivetrain.

Easy to Use:
Simply insert the Chain Checker’s pins into two chain links, gently press the swing-arm gauge, and read the measurement through the clear gauge window. Within seconds, you’ll know whether your chain needs replacement.

Compatibility & Replacement Guidelines:

  • Single-speed chains: Replace at or just before 1% wear.

Note: For SRAM® AXS 12-speed road chains, use the Park Tool CC-4.
