Abstract
A bicycle sprocket comprises a sprocket body and a plurality of sprocket teeth. The plurality of sprocket teeth includes at least one first axially recessed upshifting-facilitation tooth with respect to a rotational center axis. The plurality of sprocket teeth includes at least one first axially recessed downshifting-facilitation tooth with respect to the rotational center axis. The at least one first axially recessed downshifting-facilitation tooth is adjacent to the at least one first axially recessed upshifting-facilitation tooth without another tooth therebetween in a circumferential direction with respect to the rotational center axis. The at least one first axially recessed upshifting-facilitation tooth and the at least one first axially recessed downshifting-facilitation tooth provide a first continuous recess extending in the circumferential direction.
