Abstract: In a twist selector grip for selecting pedal cycle gear ratios, the rotary movement of the grip (3) is converted to a longitudinal movement of a tension member (2). The tension member (2) is fastened to the grip (3) and wound, similar to a screw thread, about the pedal cycle handlebar (1) or a sleeve (4) enclosing it. The tension member (2) is guided in a longitudinal guide (5) fixed in position relative to the pedal cycle handlebar (1) at a relatively great distance, in the direction of the rotation axis of the grip (3), from the fastening point (6) of the tension means (2) to the grip (3). By this construction, the arcuate distance the fastening point (6) travels, upon rotation of the grip (3), is significantly greater than the travel of the tension means (2) in its longitudinal guide (5), whereby a favorable conversion of large rotational movements of the grip (3) into small longitudinal movements of the tension means (2) is achieved.
