A coupling profile has, in a plane transversal to the axis of the bottom bracket, outer arcs belonging to the same outer circumference of the coupling, each of such outer arcs being flanked and filleted on one side to a power transmission line and on the opposite side to an idle line, in which the power transmission line and the idle line are symmetrical with respect to the outer arc that separates them. The outer arc has an angular extension about the axis of the bottom bracket equal to at least one tenth of the angular extension of the power transmission line, and the power transmission line and the idle line are filleted to the outer arc according to an angle smaller than 45.degree..
