A derailleur (2) of a bicycle gearshift (1) is described, comprising: - a support unit (3), configured to be mounted on a bicycle frame at an assembly of coaxial toothed wheels (RD) of the gearshift (1), - a mobile unit (4), comprising a chain guide, - primary actuation means (5) configured to move the mobile unit (4) with respect to the support unit (3) so as to impart onto the chain guide a primary displacement having at least a component in axial direction with respect to an axis (Z) of the assembly of toothed wheels (RD). The derailleur (2) further comprises: - secondary actuation means (6) configured to move the mobile unit (4) with respect to the support unit (3) so as to impart onto the chain guide (52) a secondary displacement having at least a component in radial direction with respect to the axis (Z) of the assembly of toothed wheels (RD), wherein the secondary actuation means (6) are capable of moving the mobile unit (4) independently of the primary actuation means (5).
