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.
