Abstract:
A selector for a bicycle gear shifting mechanism for shifting a gear-driving chain between gear stages, the shifting mechanism being operatively connected to a control cable and actuatable through user-directed movement of the control cable, comprising:a rotatable drum having a central axis and a circumferential wall for displacing the control cable helically wound thereon when said rotatable drum is rotated about the central axis; and means for selectively displacing said control cable through rotation of said rotatable drum from a first rotatable drum position associated with a first aligned position of the gear-driving chain aligned in a first gear stage to a second rotatable drum position associated with a second aligned position of the gear-driving chain aligned in a second gear stage so as to produce a cable travel which includes a correction travel for overshifting the gear-driving chain a distance beyond the second aligned position without moving the rotatable drum past the second rotatable drum position, wherein said means includes a correction cam configured to act in an axial direction of said rotatable drum so as to move a pivoting lever guiding said control cable, about a pivoting axis arranged at an angle to said central axis of said rotatable drum.
