Monitoring your disc rotor wear is essential for consistent braking performance and rider safety. This tool is designed to measure disc rotor thickness and help determine when replacement is needed quickly and accurately.
To use it, simply slide the appropriate slot on the tool over your brake rotor.
- If the rotor does not fit into the slot, it is still within the safe wear range
- If the rotor does fit into the slot, it has reached or exceeded its minimum thickness and should be replaced to maintain braking performance and safety
- 6 precision laser-cut measuring slots for wear limits of: 1.5 mm, 1.55 mm, 1.7 mm, 1.8 mm, 2.0 mm, and 2.3 mm — each slot is marked with the minimum thickness specification used by the most common disc brake rotor manufacturers.

- Integrated hole for convenient hanging or storage
- Always check the minimum thickness specification printed on the rotor or consult the manufacturer's technical documentation to confirm wear limits.
