About this item

• FAST & ACCURATE ASSESSMENT: The Chain Checker tool provides a fast and precise assessment of chain stretch and wear for nearly any bike chain. It helps to determine if a chain needs replacement to avoid poor shifting and excessive wear on the derailleur and rear cogs, which can lead to more costly problems.
• IMPORTANCE OF CHAIN REPLACEMENT: To ensure optimal performance, bike component manufacturers recommend replacing the chain at regular wear intervals. Ignoring this crucial maintenance can result in expensive repairs or replacements down the line.
• COMPATIBILITY: This chain checker is suitable for all Speed Chains, including Shimano, SRAM, Campagnolo, KMC, and other brands. It is designed to accurately measure when the chain needs to be replaced, making it an indispensable tool for bike enthusiasts and professionals alike.
• CHAIN REPLACEMENT GUIDELINES: For 5-to-10-speed chains, replace the chain at or just before the 0.75% reading. For 11-to-12-speed chains, replace at ≥ 0.5%. For single-speed chains, replace at ≥ 1%. Consult the manufacturer’s instructions for specific replacement recommendations.
• PROFESSIONAL QUALITY: The Chain Checker is a durable and high-precision tool made of high-strength aluminum alloy and steel. It is compact and easy to store, making it convenient for regular use. Routine chain wear checks can prevent shifting problems and save money by replacing worn-out parts instead of the entire system.
