A twist-grip (10) for controlling the operation of a bicycle transmission comprises a rotatable member (50) structured to be mounted coaxially around an axis of a bicycle handlebar so that the rotatable member (50) can rotate relative to the handlebar; a grip (54) disposed on the rotatable member (50) so that the rotatable member (50) can be rotated by manipulating the grip (54); an index finger portion (64) adapted to receive an index finger of a rider; a middle finger portion (68) adapted to receive a middle finger of the rider; and an intermediate portion (72) disposed between the index finger (64) portion and middle finger portion (68). The intermediate portion (72) has a flange-shaped portion (76) so that the flange-shaped portion (76) can be located between the index and middle fingers of the rider. If desired, the middle finger portion (68) may have an outer diameter less than an outer diameter of the index finger portion (64). <IMAGE> |
