<p>A bicycle speed control (1) apparatus attached to a handlebar (500) having a grip (510). This apparatus comprises a bracket (601) fixed to the handlebar and having an extension extending away from the handlebar; a support shaft attached to the extension and extending substantially perpendicular a direction in which the grip (510) extends; a shift lever (8) having a control knob (8a) provided in a distal end region thereof; and a control device for controlling a change speed wire based on a pivotal displacement of the shift lever (8). The shift lever is pivotable about the support shaft and has a range of pivotal movement such that a tangent to a substantial locus of movement of the control knob (8a) approximates the direction in which the grip (510) extends. This locus of movement is substantially within a width of the grip as seen from an end face of the support shaft. Consequently, the control knob is maintained at a substantially constant short distance to the grip throughout the range of pivotal movement of the shift lever.</p> |
