ABSTRACT:
A first shifting control device is located at a first position on the bicycle, and a second shifting control device is located at a second position on the bicycle. The first shifting control device includes a first shifting lever for causing the first shifting control device to pull and release a first transmission element, and the second shifting control device includes a second shifting lever for causing the second shifting control device to pull and release a second transmission element. An interlocking mechanism interlocks the first shifting lever and the second shifting lever so that movement of either the first shifting lever or the second shifting lever causes the bicycle shifting control apparatus to shift the bicycle transmission.
