Abstract: An electrical bicycle derailleur includes a base member and a movable member movably arranged between a retracted position and an extended position. A linkage operatively couples the movable member to the base member. The linkage includes a first link member and a second link member. The first link member is disposed closer to the base member than the second link member. A motor unit is operatively coupled to the first and second link members to rotate the first and second link members. A linkage housing is configured to support the first and second link members and the motor unit. A first diameter of the first link member is different from a second diameter of the second link member and/or a first tooth number of the first link member is different from a second tooth number of the second link member.

Abstract: A disc brake caliper is basically provided with a single main body and an end cap. The single main body includes a hydraulic cylinder bore partially defining a hydraulic chamber having a cylinder axis and an end bore disposed along the cylinder axis. The end cap is coupled to the single main body in the end bore so as to close the hydraulic chamber. The end cap has an exterior surface that is free of a tool engagement structure.
