摘要： A bicycle rear derailleur is basically provided with a base member, a link mechanism, outer and inner plate members, a guide pulley and a tension pulley. At least one of the outer and inner plate members includes a bent portion integrally formed with the at least one of the outer and inner plate members to prevent a chain from disengaging from at least one of the tension pulley and the guide pulley. The bent portion is formed by bending an inner section of the at least one of outer and inner plate members in a direction towards the other of the at least one of the outer and inner plate members. The inner section is spaced inwardly from an external peripheral edge of the at least one of the outer and inner plate members.

摘要： A bicycle rear derailleur has a base member mountable to a bicycle frame, a movable member movably coupled to the base member, a chain guide assembly rotatably connected to the movable member for rotation about a rotational axis, a biasing element configured and arranged to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member, and a fluid damper having a fluid cavity containing a volume of fluid. The fluid damper is operatively disposed between the chain guide assembly and the movable member to apply a damping force to the chain guide assembly when the chain guide assembly rotates in a second rotational direction opposite to the first rotational direction. The fluid damper has a guide wheel configured to route a chain and rotatable about the rotational axis.

摘要： A transmission casing for a bicycle has sufficient strength and rigidity and has a simple structure while being capable of hermetically sealing a transmission body of the bicycle. In a transmission casing for a bicycle is covered with a casing and a plurality of transmission shafts supported by the casing. The transmission casing includes a light-metal-made reinforcing member made of aluminum, a light alloy or the like which supports shaft portions of the plurality of transmission shafts, and a fiber-reinforced-plastic-made cover member which is integrally laminated to an inner surface of the light-metal-made reinforcing member so as to hermetically seal the transmission body. The light-metal-made reinforcing member has a strength necessary for supporting the plurality of transmission shafts, and the fiber-reinforced-plastic-made cover member has a residual rigidity by subtracting rigidity obtained by the metal-made-reinforcing member from the rigidity necessary for preventing the deformation of the whole casing.

摘要： A rear derailleur hanger alignment tool is provided with hanger attachment structure, an elongated main arm, a movable body, an indicator and an indicator positioning structure. The hanger attachment structure is attachable to a rear derailleur hanger. The movable body is movably coupled to the elongated main arm between first and second ends of the elongated main arm to slide axially along a longitudinal axis of the elongated main arm and to rotate about the longitudinal axis of the elongated main arm. The indicator is movably coupled to the movable body to move perpendicular to the longitudinal axis of the elongated main arm. The indicator positioning structure is operatively formed between the movable body and the elongated main arm to selectively maintain the indicator in a predetermined angular position with respect to the longitudinal axis of the elongated main arm.

摘要： A system for controlling gear shifting in a transmission of a cycle, includes at least one gear wheel or sprocket on which a transmission element is engaged to perform transmission of motion as a result of movement in a predetermined direction. The gear shifting is carried out by changing the position of engagement of the transmission member with respect to the at least one gear wheel or sprocket. The system further includes at least one sensor for detecting the movement in corresponding direction of movement of the motion transmitting element for generating a signal and a control unit for controlling the change of the position of the element for transmitting motion with respect to the at least one gear wheel or sprocket when the signal indicates that the element for transmitting motion is moving in the given direction.
