Abstract:
A bicycle sprocket comprises a sprocket body and a plurality of sprocket teeth provided on an outer periphery of the sprocket body and including at least one first tooth and at least one second tooth. The at least one first tooth has a driving surface side and a non-driving surface side. The at least one first tooth has a bevel cut shape in the non-driving surface side. The bevel cut shape is configured to avoid initially engaging with a bicycle chain in a shifting operation where the bicycle chain shifts from an adjacent smaller bicycle sprocket to the bicycle sprocket. The at least one second tooth is configured to initially engage with the bicycle chain in the shifting operation. The at least one second tooth is disposed adjacent to the at least one first tooth in a circumferential direction with respect to a rotational center axis of the bicycle sprocket.
