Abstract
A bicycle component is configured with an axle fixing structure. In the preferred embodiment, the bicycle component is an electric derailleur. The bicycle component has a base member rotatably supported on an axle. Preferably, the axle includes a shaft portion with a head portion disposed adjacent a first end of the shaft portion for limiting axial movement of the base member in a first axial direction of the shaft portion, and a threaded portion disposed adjacent a second end of the shaft portion with external threads. A first locking member is threaded onto the external threads and configured to limit axial movement of the base member in a second axial direction of the shaft portion. Preferably, a second locking member is threaded into the internal threads of the second end of the shaft portion to secure the first locking member on the fastening portion of the axle.
