Abstract:
A bicycle sprocket basically includes a sprocket main body, a plurality of teeth and at least one projecting member. The teeth are disposed along a circumferential direction on a radially outer side of the sprocket main body. The teeth include at least one first tooth and at least one second tooth. The at least one projecting member protrudes from an axial surface of the at least one first tooth. The at least one projecting member is a different material from the teeth. The at least one projecting member and the at least one first tooth define a first chain engaging tooth width for engaging with an outer link of a bicycle chain. The at least one second tooth defines a second chain engaging tooth width for engaging with an inner link of the bicycle chain. The first chain engaging tooth width is greater than the second chain engaging tooth width.
