Abstract
A bicycle sprocket comprises a sprocket body and sprocket teeth. The sprocket teeth include at least one first tooth and at least one second tooth. The at least one first tooth has a driving surface, a non-driving surface, a first maximum chain-engaging width, a first tooth center plane, and a first chain-facing surface. The first tooth center plane is defined to bisect the first maximum chain-engaging width in the axial direction. The first chain-facing surface is provided between the driving surface and the non-driving surface in a circumferential direction and is inclined with respect to the first tooth center plane in the circumferential direction. The at least one second tooth has a second maximum chain-engaging width defined in in the axial direction. The first maximum chain-engaging width is larger than the second maximum chain-engaging width.
