摘要： A continuous, one-piece bicycle frame end includes a forward portion and a rearward portion, wherein the forward portion extends from a chain stay and a seat stay, and wherein the rearward portion extends rearward from the forward portion. The frame end defines an axle receiving opening dimensioned to receive a bicycle wheel axle therein to rotate around a rotational axis. The axle receiving opening is intersected by a horizontal axis of a Cartesian coordinate system, wherein the axle receiving opening forms the origin of the Cartesian coordinate system, and the zero axis of the Cartesian coordinate system is the portion of the horizontal axis forward of the origin. A derailleur-attachment structure is located from approximately 180° to approximately 240° in the Cartesian coordinate system.

摘要： A bicycle rear derailleur comprises a base member; a movable member that supports a chain guide including a first pulley that rotates around a first pulley axis, wherein the pulley has a pulley plane; and a first linking member coupled between the base member and the movable member so that the chain guide moves laterally relative to the base member between a first lateral position and a second lateral position. The pulley plane intersects the first linking member when the chain guide is located at a first position between the first lateral position and the second lateral position.
