Abstract: An electrically powered bicycle equipment has an attachment/detachment seat for an electric power supply unit, and a latch assembly for holding the electric power supply unit in the seated state includes a slider having a head and a back. Either the electric power supply unit or the equipment has a sliding seat for the slider, the other one has a retaining seat for the head. The sliding seat accommodates the back of the slider, which has a peripheral groove and a ring gasket housed in the peripheral groove. The groove has two aligned sections and a deeper intermediate section between them. When the slider is in the fully advanced position, a gasket portion bridges the intermediate section between the two aligned sections, and when the slider moves back, the gasket portion can curve towards the bottom of the intermediate section of the peripheral groove.

Abstract: A bicycle electric/electronic derailleur has a plurality of mutually movable components: a support body configured to be attached to a bicycle frame, a chain guide, and a pair of connecting arms, for connection between the support body and the chain guide at respective geometric articulation axes. A geared motor controls the motion of the plurality of mutually movable components. At least one first component has a case with a chamber containing the geared motor and/or one or more electric/electronic devices. The chamber crosses at least one articulation axis. The case comprises a blind hole that is coaxial with the one axis and open outwards of the case. A second component has a pivot pivotable in the blind hole.

Abstract: A bicycle equipment is provided, including an electric power supply unit electrically connected to a first electric connector; a first component; a second component with an electrically powered device and a second connector. A through hole is provided in the first or second component. An electric connector assembly includes a third connector matching the first connector and permanently connected to the first component at a seat for the electric power supply unit; a fourth connector matching the second connector; and an electric cable extending between the third connector and the fourth connector. The through hole, the third connector and the fourth connector are sized such that the fourth connector may pass, in at least one orientation thereof, in the through hole and the third connector may not pass in the through hole.

Abstract: A bicycle rear derailleur includes a limiter assembly arranged between (i) a first component selected between the support body and the chain guide and (ii) a first connecting arm, to define an extreme value of the internal angle of the articulated parallelogram at the vertex corresponding to the articulation axis shared by them. The limiter assembly has a first member on the first component and a second member on the first connecting arm, which is configured to abut the first member when the first component and the first connecting arm are rotated in the angular direction of approach of the first member to the second member. The second member extends along at least an intermediate section in the transverse direction of the first connecting arm.

Abstract: An actuator device for a bicycle gearshift includes an actuation linkage, a drive member configured to control the deformation of the actuation linkage and comprising a motion transmission element having a rotation axis (X), and a fastening/release mechanism operatively arranged between the motion transmission element and a connection rod of the actuation linkage. The fastening/release mechanism has a first member rotatable about the rotation axis (X) as a unit with said motion transmission element, a second member rotatable about the rotation axis (X) together with said connection rod, an elastic element operatively arranged between the first member and the second member and that exerts a predetermined pre-load stress on the first member and on the second member.
