LifeLine Disc Brake Rotor Wear Indicator

Simply find the relevant slot that matches the brand of rotor you’re riding with. If the rotor slides into the slot, then it’s worn and needs replacing. If the rotor doesn’t fit in the slot, then you’ve still got enough material on the rotor to ensure effective braking.

The tool has been precisely machined to ensure you get accurate results.

The 2mm slot minimum thickness is a gauge for Tektro and TRP Ebike rotors.
