  • Patent number: 10746241
    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.
    Type: Grant

  • Patent number: 7285064
    Abstract: A bicycle gear shifting control apparatus has a manually operated shift device, a first gear shifting operation executing component, and a second gear shifting operation executing component. The manually operated shift device operates a front derailleur to shift gears. In response to operation of the manually operated shift device, the first gear shifting operation executing component executes a first gear shifting operation to move the front derailleur from a first shift position of a first sprocket to a second shift position of second sprocket. The second gear shifting operation executing component executes a second gear shifting operation to move the front derailleur a very small amount from the second shift position to a post shift position upon determining that the shifting operation should proceed.
