The present invention relates to a bicycle derailleur gear, particularly a front derailleur gear, with improved reliability that comprises a kinematic mechanism in the form of a four-bar linkage with a base body and a mobile body connected together through a pair of connecting rods hinged to the base body and to the mobile body at four pin elements, the mobile body carrying a chain guide, the four-bar linkage-kinematic mechanism being associated with derailleur gear actuation means suitable for deforming the four-bar linkage-kinematic mechanism so as to determine a displacement of the mobile body with respect to the base body and consequently a displacement of the chain guide, the derailleur gear actuation means being of the motorized type and comprising a motor casing and an outlet shaft that projects directly from said motor casing and characterized in that the actuation means command a translation in the axial direction of the outlet shaft with respect to the motor casing and are mounted between distinct components of the four-bar linkage-kinematic mechanism through interposition of at least one tilting interface about a fifth pin element substantially parallel to the pin elements.
