This chain checker is designed to work with mountain bikes (MTB) and road bikes. It is compatible with 9-speed, 10-speed, 11-speed, and 12-speed chains, making it suitable for a wide range of drivetrain setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I know when to replace my chain using this tool?\u003c\/h4\u003e\n\u003cp\u003eA: The five-level laser-engraved scale makes it easy — for 9-speed and 10-speed chains, replace the chain when the reading reaches 0.75% or before. For 11-speed and 12-speed chains, replace at 0.5% or before to prevent premature cassette and chainring wear.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What material is the chain wear gauge made from?\u003c\/h4\u003e\n\u003cp\u003eA: The main body is CNC-machined high-strength aluminum alloy with an anodized surface treatment for durability and corrosion resistance.
