Abstract
A bicycle rear sprocket comprises a sprocket body, a plurality of sprocket teeth, a shifting facilitation recess, and an upshifting facilitation projection. The plurality of sprocket teeth extends radially outwardly from the sprocket body. The shifting facilitation recess is to facilitate a shifting operation in which a bicycle chain is shifted between the bicycle rear sprocket and a smaller rear sprocket adjacent to the bicycle rear sprocket without another sprocket between the bicycle rear sprocket and the smaller rear sprocket. The upshifting facilitation projection is provided in the shifting facilitation recess to support the bicycle chain in an upshifting operation in which the bicycle chain is shifted from the bicycle rear sprocket to the smaller rear sprocket.
