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.

The advantage of the externally adjustable bias is that the shifter can be individually adjusted in terms of the retention force which prevents unintentional shifting when the bicycle is in motion.

Abstract: The brake lever system includes a cable attachment fitting which rides within an open slot of a brake lever body which tilts away from the departure point of the brake cable as a brake lever body is pivoted away from a brake lever housing. A threaded screw or rod carried within the open slot can be adjusted to raise or lower the height of a rectangular or other block which rides without turning within the open slot and which forms an adjustable lower limit below which the cable attachment fitting cannot travel.
