Abstract
A bicycle gear changing apparatus is basically provided with a controller including memory with a first prescribed shift route for upshifting and a second prescribed shift route for downshifting. The first prescribed shift route defines an order of actuation of at least one of a first gear changing device and a second gear changing device that is different from an order of actuation of at least one of the first and second gear changing devices that is defined by the second prescribed shift route. The controller controls a shifting operation of at least one of the first and second gear changing devices in response to a shift signal and in accordance with one of the first and second prescribed shift routes. The first prescribed shift route includes a least one user settable synchro-upshift point. The second prescribed shift route includes at least one user settable synchro-downshift point.
