Abstract: A derailleur comprises a base member including an engagement member for nonrotatably engaging the bicycle frame; a threaded member coupled to the base member for engaging a threaded shaft; a chain guide; and a coupling mechanism coupled between the base member and the chain guide so that the chain guide moves relative to the base member.

Abstract: A bicycle derailleur comprises a bracket adapted to be mounted to the frame; a base member supported by the bracket; a chain guide; and a coupling mechanism coupled between the base member and the chain guide so that the chain guide moves relative to the base member. The base member is supported at first and second lateral locations, wherein the bracket supports at least one of the first and second lateral locations of the base member.

Abstract: A bicycle derailleur comprises a mounting member adapted to be mounted to a bicycle frame, a base member pivotably mounted relative to the mounting member, a biasing mechanism that biases the base member clockwise relative to the mounting member when viewed laterally outwardly from the base member, a chain guide and a coupling mechanism coupled between the base member and the chain guide so that the chain guide moves relative to the base member. A rotation restricting mechanism is disposed in a force communicating path between the mounting member and the base member to restrict counterclockwise rotation of the base member relative to the mounting member.

Abstract: A bicycle control device is disclosed having a control lever that is operable in a first direction to operate the brake control mechanism, a second direction to operate the shift control mechanism in the pulling direction and a third direction to operate the shift control mechanism in the release direction. In a preferred embodiment of the invention, when viewed from the perspective of a rider on the bicycle, the first direction is the direction of movement of the lever toward the handlebar. The second direction is the direction of movement of the control lever downward and the third direction is the direction of movement of the control lever upward. In a more preferred embodiment, the second and third directions are perpendicular to the first direction.

Abstract: A bicycle hub assembly has a hub axle with a nut, a hub shell rotatably support the hub axle by a bearing assembly disposed between the hub axle and the hub. The hub axle and the nut form a bicycle hub axle assembly that is especially configured to permit easy removal and/or installation of a rear derailleur. The hub axle includes a shaft portion having a threaded section at a first axle end and a head portion fixed to a second axle end. The nut has a body portion with a projection extending axially from a frame engaging surface, and a threaded bore threadedly engaged with the threaded section of the shaft portion to secure the bicycle hub axle assembly to the bicycle frame. The projection is configured to engage a slot in a bicycle frame to prevent rotation of the nut relative to the bicycle frame.

Abstract: A shifting apparatus for a bicycle includes a takeup element for winding and unwinding a control cable, a first shift member supported to be rotatable substantially along an outer periphery of a handlebar for rotating the takeup element, a second shift member supported by the handlebar for rotating the takeup element backward, and a positioning mechanism for retaining the takeup element in a selected angular position. An interlock mechanism is provided for interlocking the first shift member and takeup element, such that the takeup element is not always rotatable with the first shift member. This interlock mechanism allows the first shift member to remain still when the takeup element is rotated backward in an unwinding direction. Further, the shifting apparatus is constructed at low cost, with the first shift member having an axis of rotation extending at an angle to a handlebar axis.
