Abstract: A rotor cover is provided that limits contact of a disc brake rotor with an object flying from a radially outer side of the disc brake rotor. The rotor cover covers a disc brake rotor, which is rotatable relative to a bicycle frame. The rotor cover includes a circumferential part that at least partially covers a circumferential edge of the disc brake rotor at a radially outer side of the disc brake rotor. The circumferential part includes at least three first pieces facing the circumferential edge of the disc brake rotor, and first openings provided between two adjacent ones of the first pieces in a circumferential direction of the disc brake rotor.
