A bicycle crankset annular body with a toothed crown that extends about a rotation axis and has axially inner and outer surfaces and a reference plane (R) on which the rotation axis (O) and a longitudinal axis of a right crank arm lies. The annular body's maximum axial thickness, defined at a first angular portion, is between two parallel planes that are orthogonal to the reference plane (R). The angular portion has a lightening recess formed on the axially outer surface between two delimiting planes that pass through the rotation axis (O) and are inclined with respect to the reference plane (R) by first and second angles which are measured on axially outer surface moving angularly in the clockwise direction from the reference plane (R).
