An inner tube moves axially between an outer tube and a support, all of which are concentrically arranged, to a desired telescopic position, relative to the outer tube and the support, and can be locked in the desired telescopic position by applying radial force between the support and the inner surface of the inner tube. The radial force generates a frictional force acting on the inner surface of the inner tube, which resists longitudinal movement of the inner tube. A bicycle actuator cable is coupled to an actuator connector for a tension-controlled actuator by a bicycle cable connector which has a fixed longitudinal position on the bicycle actuator cable. The bicycle cable connector is longitudinally consistently removably repeatably interengageable with the actuator connector to maintain longitudinal alignment of the bicycle actuator cable with the actuator through repeated engagement and disengagement of the bicycle cable connector and the actuation connector.
