    • A gear reduction apparatus for a bicycle component comprises a gear support, a first gear coupled to the gear support for receiving rotational drive force from a drive component, and a second gear coupled to the gear support for communicating rotational drive force to a driven portion of the bicycle component. The first gear is operatively coupled to the second gear to communicate rotational drive force from the drive component to the driven portion of the bicycle component, and the first gear, the second gear and the gear support are coupled together so that the first gear, the second gear and the gear support may be coupled to and removed from the drive component and the driven portion of the bicycle component as a self-contained unit.
    • 用于自行车部件的齿轮减速装置包括齿轮支撑件,联接到齿轮支撑件的用于接收来自驱动部件的旋转驱动力的第一齿轮和联接到齿轮支撑件的第二齿轮,用于将旋转驱动力传递到驱动部分的被驱动部分 自行车部件。 第一齿轮可操作地联接到第二齿轮以将来自驱动部件的旋转驱动力传递到自行车部件的从动部分,并且第一齿轮,第二齿轮和齿轮支撑件联接在一起,使得第一齿轮, 第二齿轮和齿轮支撑件可以作为独立单元联接到自行车部件的驱动部件和被驱动部分并被移除。
