If it's a disc brake bike, then Rotor is another name for the brake disc.

If it's a BMX rotor may be another name for gyro / detangler - the thingy that lets you spin the bars on a brake-equipped bike w/o making a mess of the brake wires.

This tool is used in bike maintenance to ensure that the rotor is properly installed and aligned with the brake caliper, which helps maintain the braking performance and safety of the bike.


What is the purpose of a brake rotor on a bike and how does it contribute to the overall braking system?

The purpose of a brake rotor on a bike is to provide a surface for the brake pads to grip onto and create friction, which slows down the bike when the brakes are applied. The brake rotor contributes to the overall braking system by converting the kinetic energy of the moving bike into heat energy through friction, which helps to stop the bike efficiently and safely.
