Piece Bicycle Chain Gauge, Quick and Easy Wear Indicator, Stainless Steel

Material: Stainless steel, easy to use and carry. Accurate detection: This tool quickly checks chain stretch and wear to determine if the chain is good or bad.

Accurate and durable for solving most bicycle problems. Check chain wear: If it is stuck at 0.75, it means the chain is worn but can still be used for a while. If it remains stuck at 1.0, it means the chain is very worn and it is generally recommended to replace it immediately.

Chain hooks: 2 hooks at the top of the integrated chain hold the links during assembly. The operation is more convenient, preventing greasy hands and chain slippage, allowing you to work more efficiently.

Measuring thread diameter: Insert the screw to be measured into the hole and slide it towards the small hole.

If it cannot be pushed in, observe the stop position number to determine the thread diameter.
