1. A bicycle sprocket comprising:
sprocket teeth including
at least one first tooth configured to engage with outer link plates of a bicycle chain and having a first radial-tooth height, the at least one first tooth having a first chain-engaging axial width which is smaller than a first distance defined between opposed outer link plates of the bicycle chain and which is larger than a second distance defined between opposed inner link plates of the bicycle chain, the first radial-tooth height being greater than the first chain-engaging axial width, and
at least one second tooth adjacent to the first tooth, the at least one second tooth being configured to engage with inner link plates of the bicycle chain, the at least one second tooth having a second radial-tooth height, the at least one second tooth having a second chain-engaging axial width which is smaller than the second distance, the second radial-tooth height being greater than the second chain-engaging axial width; and
the first radial-tooth height being greater than the second radial-tooth height, and
the at least one second tooth having a leading edge having a concave curved surface portion that extends directly from a radially outermost end thereof.
