Abstract: A rear bicycle derailleur includes a base member, a movable member, a guide arm and a tension arm. The base member is adapted to be mounted to a bicycle frame. The movable member is movably coupled to the base member, preferably via a linkage, to move between a retracted position and an extended position. The guide arm is pivotally coupled to the movable member around a first axis and has a guide sprocket. The tension arm is pivotally coupled to the movable member around a second axis and has a tension sprocket. Preferably, the guide arm is freely pivotal about the first axis without being rotationally biased, while the tension arm is rotationally biased by a biasing member about the second axis. Preferably, the guide arm and the tension arm are configured and arranged to move independently of each other.

Abstract: It is the problem to provide a rear derailleur having structure in which even when the chain has been looped over a chain wheel of major diameter, the tension sprocket wheel does not come so closer to the ground to thereby reduce accidents of a violent fall or trouble. Further, it is the problem to facilitate detachment and attachment of the wheel, and to provide a rear derailleur having a wide application range to wheel size. To solve these problems, the guide arm and the tension arm are capable of rocking around the guide arm rocking axis and the tension arm rocking axis which are different from each other, and these arms are rocked independently of each other, and the distance between the guide sprocket wheel and the tension sprocket wheel varies with the speed variation state.

The first and second tread surfaces provide different use modes. The first tread surface (4) includes a cleat engaging device (4a) for engaging a cleat, and the second tread surface (7) defines an antislip device (16) suited to treading by a shoe. In an alternative pedal system, the first tread surface (14) defines an antislip device (16) suited to treading by a shoe, and the second tread surface (19) includes a cleat engaging device (20, 21).

Abstract: A connecting structure between a bicycle pedal and a cleat, comprising hooks pivotably supported by a pedal body for engaging and releasing the cleat, and an urging device for urging the hooks toward engaging positions. The object is to allow the cleat to be released with increased reliability when, for example, the cyclist falls over with his shoe becoming obliquely inclined relative to the pedal. A first cam mechanism is provided between each of the hooks and the cleat for causing the hook to pivot in a releasing direction when the cleat is inclined about a first imaginary axis extending substantially along a direction of pivotal movement of the hooks. The first cam mechanism includes a first pressed edge defined on one of the hooks and opposed to the cleat, and a first pressing edge defined on the cleat and opposed to one of the hooks for slidable contact with the first pressed edge.

Abstract: A brake control apparatus for a bicycle. The appratus has a control lever operatively connected with a control cable for pulling the cable and a force transmission ratio adjuster mechanism for adjusting a force transmission ratio in association with an operation of the control lever. The force transmission ratio is defined as a ratio obtained by dividing an output force from the cable associated with application of a unit input force to a certain lever position of the control lever. With the appratus of the invention, this force transmission ratio is so determined as to have a maximum value at a position during an entire stroke of the lever between a stroke start end and a stroke finish end and the maximum value position is on the side of the finish end after a play stroke on the side of the start end.

Abstract: An apparatus for coupling a cleat has a pedal shaft for rotatably supporting a pedal, a tread surface extending parallel to the pedal shaft for contacting a bottom of a shoe, a first pivotal axis provided on the pedal, and a first cleat clamp pivotable about the first pivotal axis. The first cleat clamp includes a recess for engaging one end of the cleat until a force exceeding a predetermined value is applied thereto. Further, this apparatus has a second cleat clamp opposed to the first cleat clamp across the pedal shaft, and a pair of restrictor projections disposed between the second cleat clamp and the pedal shaft for restricting displacement to the cleat. The second cleat clamp cooperates with the first cleat clamp to couple the cleat to the pedal. The restrictor projections are spaced apart from each other by a distance greater than a width along the pedal shaft of a portion of the cleat for contacting the restrictor projections.

The cable connector is connected to the lever via an adjusting mechanism for so that the return position of the brake lever relative to a lever bracket may be adjusted to accommodate various sized hands. Further, the adjusting mechanism allows for adjustment of a lever ratio A which is defined mathematically by the distance between the pivot point of the lever and the pivot point of the cable connector on the lever divided by the distance from a set point on the brake lever to the pivot point of the lever.
