Abstract
A gear selection device for a variable gear mechanism, especially for a bicycle gear drive mechanism, with a control device, which acts via a force-transmitting element on the variable gear mechanism; with an actuating device with a rotatable actuating element for manual actuation of the control device; and with a display device with an indicator element, which can move along an arc to display the engaged gear selected via the actuating device. The angular movement of the actuating device or control device is transmitted via a transmission device to the display device in such a way that the arc through which the indicator element of the display device passes is smaller than the arc through which the actuating element of the actuating device passes as the same time. This improves the readability of the display device and also improves the ergonomics of the gear selection device.
