A worn chain shifts poorly and accelerates sprocket wear. The Park Tool CC-3.2 chain wear tool accurately shows when your chain needs replacing, helping prevent premature drivetrain damage and potentially costly repairs.

• Designed to accurately indicate when a chain reaches 0.5% and 0.75% wear - the point at which most chain manufacturers suggest replacement
• Longer design measures a greater length of chain, giving greater accuracy
• Made from precision, laser cut steel
• Not suitable for SRAM® Flattop™ and SRAM® T-Type 12-speed chains
