ROTOR (DISC BRAKE)
The rotor (also called a disc) is the metal disc component of a disc brake system that is bolted to the wheel hub. The brake pads inside the caliper clamp onto the rotor to slow the bicycle.
Rotors come in different sizes (typically 140mm to 220mm in diameter). Larger rotors provide more braking power and better heat dissipation. Common sizes are 160mm for cross-country mountain biking and road use, and 180-200mm for enduro and downhill mountain biking where heat management from long descents is critical.
