Abstract
A bicycle front sprocket has a sprocket body and a chain engagement structure. The sprocket body has a center rotational axis, a first side surface and a second side surface. The second side surface is a smaller sprocket facing side. The chain engagement structure is disposed on an outer periphery of the sprocket body. The chain engagement structure includes a plurality of sprocket teeth extending radially outward from the outer periphery of the sprocket body. The sprocket teeth include at least one first tooth having a first tooth top with a first leading edge and a first trailing edge. The first leading edge is positioned downstream from the first trailing edge with respect to the driving-rotational direction of the bicycle sprocket. The first tooth top is shaped so that the first leading edge is positioned closer to the first side surface than the first trailing edge in the axial direction.
