The first sprocket includes a first sprocket body anda plurality of first sprocket teeth disposed on a first outer periphery of the first sprocket body; the second sprocket includes a second sprocket body and a plurality of second sprocket teeth. The second sprocket teeth are disposed on a second outer periphery of the second sprocket body. The sprocket carrier includes a torque transmitting profile and a sprocket mounting portion. The chain guidingportion is positioned between the first and second sprockets in an axial direction parallel to a rotational center axis of the bicycle front sprocket assembly. At least one of the first and second sprockets is mounted to the sprocket mounting portion of the sprocket carrier by a non-threaded fastener.

    本发明提供基本上具有第一链轮、第二链轮、链轮载架和链条引导部分的自行车前链轮组件。第一链轮包括第一链轮主体和设置在该第一链轮主体的第一外周上的多个第一链轮齿。第二链轮包括第二链轮主体和多个第二链轮齿。第二链轮齿设置在该第二链轮主体的第二外周上。链轮载架包括转矩传递轮廓和链轮安装部分。链条引导部分沿与自行车前链轮组件的旋转中心轴线平行的轴向方向被定位在第一链轮齿和第二链轮齿之间。第一和第二链轮中的至少一个通过非螺纹紧固件被安装到链轮载架的链轮安装部分。
