Disc Rotor
A disc rotor is an important part of a modern bicycle's braking system. It's the flat, round metal disc attached to the wheel that helps the bike stop when brake pads squeeze against it. This system is similar to what you might find in cars but scaled down for bicycles. Some bikes use traditional rim brakes, but disc rotors are becoming more common, especially on mountain bikes and higher-end road bikes, because they work better in wet conditions and provide more reliable stopping power. You might also see this component referred to as a "brake rotor" or "brake disc" in job descriptions and resumes.
