The present disclosure relates to devices and methods of converting a bicycle frame from a mechanical gear-shifting configuration to an electronic gear-shifting configuration and vice versa. In a representative embodiment, a method of converting a bicycle frame from a mechanical gear-shifting configuration to an electronic gear-shifting configuration comprises removing a mechanical cable extending between a mechanical gear-shift actuator and a mechanical gear shifter via a cable stop of a removable bracket member secured to a down tube member of the bicycle frame, and removing the removable bracket member from the down tube member of the bicycle frame. The method further comprises mounting an electronically-actuated gear shifter to the bicycle frame in electrical communication with an electronic gear-shift actuator such that actuation of the electronic gear-shift actuator causes the electronically-actuated gear shifter to shift gears.

A device for shortening the spring path of a suspension fork for bicycles includes a cable; a fixing device for fixing the cable to the suspension fork tubes, which can be moved relative to the bicycle frame; and a cable clamping device, which can be secured in the region of the handlebar, preferably on the front-end section, for detachably fixing the cable, wherein the spring path is shortened in an infinitely variable manner. Thus, an infinitely variable lowering device is produced which is independent of a suspension fork.

A rotor system for a bicycle (1), for the purpose of bearing a fork (8) and transmitting the actuations of Bowden cables (31, 32), which each having a core (31a; 32a) includes first and second transmission elements (36, 37), that rotate relative to one another and are arranged in the area of the bearing (21, 23, 25) of the fork (8). The transmission elements include an annular region, mounted on a fork steerer (12) and surrounded by a head tube (21), and connection areas (36b; 37b) for the direct or indirect attachment of the rotor-side ends of the cores (31a 32a). At least one of the transmission elements (37) includes a connection area (37b) with a connecting element, which (32b) can be form-fittingly attached, interacting with, or being integrally connected to, the rotor side end of the core (32a) that is assigned with said at least one transmission elements (37).

Cable coupling assemblies are described which can be readily engaged and separated from one another. The couplings are particularly useful for use in torque transmitting cables such as those used in drain cleaning applications.
