摘要： A top pull type front derailleur is designed to move or shift a chain between two or more sprockets for changing gears. The front derailleur basically has a bicycle frame clamping band, a linkage assembly and a chain guide. The linkage assembly includes a cable connection point and is arranged between the bicycle frame clamping band and the chain guide to move the chain guide laterally towards and away from the clamping band. The clamping band has a top pull cable guide surface that is configured and arranged relative to the clamping band to guide a cable from vertically above the clamping band to the cable connection point when the front bicycle derailleur is operatively mounted to a bicycle frame. Preferably, the top pull cable guide surface is formed on a peripheral surface of a roller that is rotatably mounted on the clamping band.

摘要： An assisting apparatus that uses power from a rotating member to assist the operation of a bicycle transmission includes a mounting member; a cam member coupled to the mounting member for rotation around a cam axis, wherein the cam member has a cam surface; a cam follower cooperating with the cam surface for moving in response to rotation of the cam member; a transmission actuating element coupling member for communicating movement of the cam follower to a transmission actuating element; a first coupling member coupled for rotation of the cam member, wherein the first coupling member moves between a first engaged position and a first disengaged position; an operating member for moving the first coupling member to the first engaged position; and a decoupling member that moves the first coupling member to the first disengaged position in response to a rotational position of the cam member. The first coupling member selectively engages and disengages the rotating member so that the rotational force of the rotating member may be used to assist the shifting operation.
