摘要：
A speed control device, which is adapted to be used in connection with a derailleur type bicycle or internal gear hub type bicycle, has one operation mode for up-shifting the speed and another operation mode for down-shifting the speed. The two operation modes can be affected by an operation lever, and with the operation lever being pivoted in a second rotation direction for the up-shifting operation and in a first rotation direction for the down-shifting operation.
