A bicycle derailleur is basically provided with a base member, a movable member, a coupling structure and an attachment member. The base member is configured to be mounted to a bicycle. The base member has an inner wire guide. The inner wire guide has an inlet portion and an outlet portion. The movable member supports a chain guide. The coupling structure movably couples the movable member to the base member so that the movable member is selectively movable relative to the base member. The attachment member is detachably and/or rotatably attached to the outlet portion of the inner wire guide.

The present disclosure relates to devices and methods of converting a bicycle frame from a mechanical gear-shifting configuration to an electronic gear-shifting configuration and vice versa. In a representative embodiment, a method of converting a bicycle frame from a mechanical gear-shifting configuration to an electronic gear-shifting configuration comprises removing a mechanical cable extending between a mechanical gear-shift actuator and a mechanical gear shifter via a cable stop of a removable bracket member secured to a down tube member of the bicycle frame, and removing the removable bracket member from the down tube member of the bicycle frame. The method further comprises mounting an electronically-actuated gear shifter to the bicycle frame in electrical communication with an electronic gear-shift actuator such that actuation of the electronic gear-shift actuator causes the electronically-actuated gear shifter to shift gears.

The invention relates to a bicycle frame made of fiber-reinforced material, particularly of plastic reinforced with carbon fibers, having a rear wheel suspension for supporting the rear wheel. According to the invention, a receptacle is formed on at least one of the two chain stays of the rear wheel suspension, in which a replaceable adapter plate adapted to the hub of each rear wheel to be used is removably fastened, in which the axle of the rear wheel can be supported.

A bracket apparatus for mounting a derailleur to a frame of a human-powered vehicle comprises a bracket body and one of a restriction member and a restriction opening. The bracket body includes a frame attachment portion configured to be attached to the frame of the human-powered vehicle and a derailleur attachment portion to which the derailleur is to be attached. The restriction member is configured to be at least partly provided in the restriction opening to restrict a rotation of the bracket body relative to the frame of the human-powered vehicle in a bracket mounting state where the bracket apparatus is mounted to the frame of the human-powered vehicle.

A bicycle gearshift mechanism has a base element, a pivot mechanism, a movable element, and a chain guide arrangement. The pivot mechanism connects the base element to the movable element. The chain guide arrangement is connected, rotatably about a rotary axle, to the movable element. The base element comprises a first attachment end, which is coaxial with respect to the rear-wheel axle or axis, and a second attachment end for coupling to the pivot mechanism.
