TOOPRE 3-in-1 Bicycle Chain Wear Gauge Stainless Steel Chain Checker Tool for MTB Road Bike Chain Wear, Chain Hook & Screw Measurement

Keep your bike drivetrain in good condition with the TOOPRE Chain Wear Measurement Ruler. This multifunctional tool combines chain wear measurement, chain hook function, and screw measurement in one compact design, making it ideal for mountain bikes, road bikes, and daily bicycle maintenance.

The tool is made of 201 stainless steel, offering strong durability and long service life. Its sandblasted surface provides a clean, smooth, high-gloss finish with no burrs, making it comfortable and safe to use.

The three-stage chain wear measuring system allows you to check chain elongation at 0.5%, 0.75%, and 1%. This gives a more detailed understanding of chain wear, helping you decide when maintenance or replacement is needed. Replacing a worn chain in time can help reduce wear on the cassette, chainring, and other drivetrain components.

In addition to chain wear checking, the built-in chain hook helps hold the chain during installation, removal, or cleaning. The screw measuring function can also be used to measure screw length and thread diameter, making this tool convenient for bike repair and workshop use.

Specifications

How to Use

1. Place one end of the chain gauge into the chain roller.
2. Let the other measuring end fall naturally into the chain.
3. Check which stage can enter the chain:
   • 0.5%: Slight chain wear
   • 0.75%: Moderate chain wear
   • 1%: Chain is heavily worn and should be replaced in time

When the chain wear reaches 1%, it is recommended to replace the chain promptly to avoid excessive wear on the cassette and chainring.
