One way clutch mechanism for a bicycle freewheel hub, which comprises a driver having one or more sprockets thereon and co-axial and relatively rotatable with respect to a stationary axle, a hub shell co-axial and relatively rotatable with respect to the axle, an inward conical clutch face formed on or with the hub shell, an internally threaded clutch member co-axially and relatively rotatably mounted on a threaded section of the driver so as to axially move back and forth; an outward conical clutch face formed on or with the clutch member, and a coil spring so arranged as to urge the clutch member axially inwardly thereby to force the outward clutch face away from the inward clutch face.
