Abstract: A bicycle electric/electronic derailleur has mutually movable components, and a geared motor for controlling the mutual motion of the components. The geared motor includes an electric motor having a drive shaft, an output shaft and a speed reducer including at least one gear between the drive shaft and the output shaft. The output shaft defines at least in part one of the articulation axes. The electric motor is rigidly connected to a first component, and a second component integrally rotates with the output shaft. The derailleur further includes a magnetic rotary encoder for transducing a quantity related to the mutual motion of the components. The encoder includes a permanent magnet and a sensor responding to the changes in the magnetic field of the magnet. The magnet is a disc, cylindrical or annular magnet having diametral magnetization, and is coaxial with and arranged to integrally rotate with the output shaft.

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: An electrically powered bicycle equipment has a component with a seat for removable attachment of an electric power supply unit, and a clamping device of the electric power supply unit to the component. The clamping device is pivotally supported by the component or the electric power supply unit about a first geometric axis stationary with respect thereto, and about a second geometric axis, which is parallel to, pivotal about, and not translatable with respect to, the first geometric axis. Either the component or the electric power supply unit has a retainer member and the clamping device has a retainable member that is urged against the retainer member. The rotation of the clamping device in a first direction about the first axis and in a second direction opposed to the first direction about the second axis allows the retainable member to be brought beyond the retainer member during clamping and unclamping.

A cable-clamping washer includes with a cable-bending appendage that is insertable in the seat of the actuation arm. The actuation arm cooperates with the cable-bending appendage to lock an actuation cable in the desired position.

Abstract: A bicycle control cable actuation device having: a casing, configured for fixing to bicycle handlebars, a cable-winding bush, on which the control cable is wound and which is angularly mobile in the casing about a main axis of the device, an indexing bush that is coaxial to and associated with the cable-winding bush to removably hold the cable-winding bush in predetermined positions that are angularly spaced from each other by predetermined indexing angles, a manoeuvring mechanism, operative on the cable-winding bush to rotate it in a first angular direction about the main axis of the device, to obtain an upward gearshifting; and, a predetermined circumferential clearance corresponding to a predetermined gearshifting extra-stroke angle is provided between the cable-winding bush and the indexing bush.

Abstract: A clamp configured for connecting a bicycle component to a tubular element of the bicycle. The body of the bicycle component has a through opening extending between surfaces of the body and a seat on one surface that connects with the through opening. The clamp has an annular band that is connected to a slider in the through opening. An actuation lever connected to the slider moves the slider between a release position and a clamping position. When the slider is in the claiming position, the actuation lever is position in the seat on the body.

Abstract: A derailleur comprising a chain guide, a fixed body adapted for being fixedly associated with a part of frame of the bicycle, and an actuation arm hinged to the fixed body. A cable-clamping washer constrained to the actuation arm locks a control cable on the actuation arm. A first fastening station and a second fastening station are defined on said actuation arm and configured to fasten the control cable in different positions on the actuation arm. An anti-rotation appendage projecting from the chain-clamping washer is adapted for being inserted in a holding seat of the actuation arm and holding the control cable in at least one of the first and the second fastening stations.

Abstract: A pin for a crown of a bicycle crankset that includes a mounting portion configured to be fixed to the crown, a chain engaging portion having a first face that faces towards said mounting portion for engaging a plate of a link of a bicycle chain, and a second face that faces the opposite way with respect to said mounting portion. The second face has at least one first surface portion inclined by a first angle smaller than 90° when measured in a longitudinal section plane of the pin.

Abstract: A device for actuating a bicycle front derailleur and displacing a transmission chain between toothed wheels of different diameters. An indexer associated with the derailleur comprises a first stop position and a second stop position. The first stop corresponds to engagement of the transmission chain on a first toothed wheel and the second stop position corresponds to engagement of the transmission chain on a different toothed wheel. A control lever operatively active on the indexer switches between the stop positions with a single actuation of the control lever.

Abstract: A bicycle front derailleur that is movable between shift positions in association with an indexer. The inner mechanical end stop is adjusted at the first indexing position so there is no loosening of the control cable in the last downward gearshifting operation, with the benefit of an immediate and rapid response in the first upward gearshifting operation. The outer end stop is adjusted to interrupt the rotation of the cable-winding bush before it reaches the last indexing position. This pair of mechanical end stops limits the excursion of the derailleur to prevent it being able to shift the chain too much towards the frame or too much away from the frame, which ensures that the chain is not shifted beyond the gears.

Abstract: A bicycle gearshift cable control device that is rotatable about a control pin, in opposite angular directions, and has an indexer mounted coaxially to the control pin that defines a plurality of spaced apart, stable angular positions for the cable-winding bush. Elastic members that store elastic energy during a rotation of the control pin in one angular direction and release the stored elastic energy stored at the end of the rotation of the control pin are configured to cause a stroke recovery rotation of the control pin in the opposite angular direction during the release of the stored elastic energy. The stroke recovery rotation is smaller than the indexing angle that separates two adjacent stable positions of the cable-winding bush.
