The invention discloses a super variable-speed gear which is in such a structure that a rotary disassembling wheel frame (2) provided with hook type wheel teeth (1) is installed on fixed arms (4); struts (3), return springs (8), steel wire ropes (6) and rollers (5) are installed on an inner wheel assembly (7). According to the invention, the variable-speed function is fulfilled by using the steel wire ropes, the struts, the hook type wheel teeth and the rotary disassembling wheel frame, and the original limited shift speed variation is replaced by current N shift speed variation. By applying the super variable-speed system, people riding a bicycle can choose a suitable shift speed according to different terrains more conveniently.
