The present invention provides a bicycle sprocket and a bicycle sprocket assembly. The bicycle sprocket 14 has a rotational center axis X. The sprocket 14 has a first tooth 32a and a second tooth 32b.The first tooth 32a has a first axial chain engagement width W1. The first axial chain engagement width W1 is smaller than the first axis distance L1 of an outer flap 2a. Further, the first axial chain engaging width W1 is larger than a second axial distance L2 of an inner plate 2b coupled to the outer plate plates 2a. The second tooth 32b has a second axial chain engagement width W2. The secondaxial chain engagement width W2 is smaller than the second axis distance L2. The second tooth 32b is formed by deforming the material. 本发明提供一种自行车用链轮和自行车用链轮组合体，该自行车用链轮(14)具有旋转中心轴心(X)。该链轮(14)包括第一齿(32a)和第二齿(32b)。第一齿(32a)具有第一轴方向车链卡合宽度。第一轴方向车链卡合宽度(W1)比外连件上的第一轴方向间隔(L1)小。并且，第一轴方向车链卡合宽度(W1)比与外连板(2a)连结的内连板(2b)上的第二轴方向间隔(L2)大。第二齿(32b)具有第二轴方向车链卡合宽度(W4)。第二轴方向车链卡合宽度(W4)比第二轴方向间隔(L2)小。第二齿(32b)通过材料的变形形成。
