kli XI / Klickbox

Development of a novel Klickbox concept for hub gears , which allows disassembling of the rear wheel without tools. Unlike previous solutions the Klickbox always remains firmly on the frame.
The hub pin and dropouts are parallel arranged. By a quick-release the Bowden cable can be relieved, the hub pin is now free. If one opens the quick-releases, which are fixing the hub, to both sides now, the wheel can be directly removed. The opened quick-releases now serve as comfortable handles. Another advantage: no new alignment of the gears required.
