Bicycle sprocket

A bicycle sprocket comprising:

• a sprocket body having a first axially-facing surface and a second axially-facing surface with respect to a rotational center axis of the bicycle sprocket, the second axially-facing surface being opposite to the first axially-facing surface in an axial direction with respect to the rotational center axis, the first axially-facing surface being configured to face a center plane of a bicycle in an assembled state where the bicycle sprocket is mounted to the bicycle;
• a plurality of sprocket teeth extending radially outwardly from the sprocket body with respect to the rotational center axis;
• the plurality of sprocket teeth including at least one first axially recessed upshifting-facilitation tooth with respect to the rotational center axis, the at least one first axially recessed upshifting-facilitation tooth being recessed from the second axially-facing surface toward the first axially-facing surface;
• the plurality of sprocket teeth including 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 being recessed from the second axially-facing surface toward the first axially-facing surface, the at least one first axially recessed downshifting-facilitation tooth being 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;
• and
• the at least one first axially recessed upshifting-facilitation tooth and the at least one first axially recessed downshifting-facilitation tooth providing a first continuous recess extending in the circumferential direction.
