A bicycle sprocket assembly includes a first sprocket and a second sprocket. The first sprocket includes a plurality of first sprocket teeth, a first sprocket inward surface, a first sprocket outward surface, and an axial space. The second sprocket includes a plurality of second sprocket teeth, a second sprocket inward surface, and a second sprocket outward surface. In an engaged state in which one of the plurality of second sprocket teeth is located between the axially inward inner link plate and the axially outward inner link plate in the axial direction, an axial space is defined between the first sprocket outward surface and the axially outward inner link plate in the axial direction when the second sprocket outward surface contacts the axially outward inner link plate. The axial space is greater than 0 mm and equal to or less than 0.15 mm.
自行车链轮组件包括第一链轮和第二链轮。第一链轮包括多个第一链轮齿、第一链轮向内表面、第一链轮向外表面和轴向空间。第二链轮包括多个第二链轮齿、第二链轮向内表面、第二链轮向外表面。在多个第二链轮齿中的一个在轴向方向位于轴向向内内链板与轴向向外内链板之间的啮合状态下,当第二链轮向外表面接触该轴向向外内链板时,轴向空间限定为在轴向方向在第一链轮向外表面和轴向向内外链板之间。轴向空间大于0mm并且等于或小于0.15mm。
