The invention relates to a bicycle rear wheel sprocket pair for positively engaging with a bicycle roller chain in a force-transmitting manner, the rear wheel sprocket pair being rotatable about a sprocket shaft, the sprocket shaft defining an axial direction along the sprocket shaft, a radial direction orthogonal to the sprocket shaft and a circumferential direction around the sprocket shaft, wherein the rear wheel chain wheel pair comprises a larger chain wheel and a coaxial smaller chain wheel axially adjacent to the larger chain wheel, the smaller chain wheel is connected with the larger chain wheel so as to jointly rotate around the chain wheel shaft in a non-sliding manner, the larger chain wheel has an even number of teeth equal to or smaller than 22 teeth, and the smaller chain wheel is connected with the larger chain wheel so as to rotate around the chain wheel shaft in a non-sliding manner. And wherein the difference in the number of teeth between the larger sprocket and the smaller sprocket is exactly two teeth.

    本发明涉及一种用于以传力的方式与自行车滚子链形状配合地啮合的自行车后轮链轮对,其中所述后轮链轮对可绕链轮轴旋转,其中所述链轮轴界定了沿所述链轮轴的轴向、与所述链轮轴正交的径向和环绕所述链轮轴的周向,其中所述后轮链轮对包括一个较大的链轮和一个在轴向上紧邻所述较大链轮的同轴的较小的链轮,所述较小链轮与所述较大链轮连接以便共同以无滑动的方式绕所述链轮轴旋转,其中所述较大链轮具有等于或小于22个齿的偶数齿数,且其中所述较大链轮与所述较小链轮间的所述齿数的差为刚好两个齿。
