A reduction ratio changing device, so-called DCRR, for a mechanical chain transmission system includes a toothing. The toothing of the DCRR includes a portion, so-called the helical portion, forming a toothed helix winding around an axis of revolution of the DCRR and a portion, so-called the circular portion, forming a toothed planar circle whose centre coincides with the axis of revolution of the DCRR. The helical portion of the toothing extends from a distal end of the toothing of the DCRR towards the circular portion of the toothing. The circular portion of the toothing of the DCRR forms a proximal end of the toothing of the DCRR.
