Abstract
A control apparatus for controlling a drive member rotatably supported on a bicycle includes a mounting member for mounting the apparatus to the bicycle, a braking mechanism coupled to the mounting member for applying a braking force to the drive member; and a coupling mechanism adapted to couple the braking mechanism to a shift control mechanism so that the braking mechanism applies the braking force to the drive member upon actuation of the shift control mechanism.

A control apparatus for controlling a drive member rotatably supported on a bicycle comprising:
- a mounting member for mounting the apparatus to the bicycle;
- a braking mechanism coupled to the mounting member for applying a braking force to the drive member;
- and
- a coupling mechanism adapted to couple the braking mechanism to a shift control mechanism so that the braking mechanism applies the braking force to the drive member upon actuation of the shift control mechanism.
A control apparatus for controlling a drive member rotatably supported on a bicycle comprising:
- a mounting member for mounting the apparatus to the bicycle;
- a rotary member rotatably supported to the mounting member;
- a first braking member;
- a first cam member coupled to the mounting member;
- a second cam member coupled to the rotary member for rotation therewith;
- wherein at least one of the first cam member and the second cam member moves the first braking member when the first cam member and the second cam member rotate relative to each other;
- a coupling pawl coupled to the rotary member;
- a pawl biasing member for biasing the coupling pawl toward a coupled position for coupling the rotary member for rotation with the drive member;
- and
- a pawl control member for retaining the coupling pawl in a decoupled position.
