ABSTRACT:
A speed-change operating mechanism which actuates a push rod at a speed transmission hub for a bicycle by means of a control wire so as to change the bicycle speed. The mechanism comprises a first operating member for actuating the rod, a second operating member oscillated with the control wire and an adjustor for adjusting the relative position between both the first and second members, through which adjustor the first operating member becomes cooperable with the second operating member, thereby easily and precisely adjusting the travel of the push rod with respect to the control wire.
