A bicycle front derailleur with an integral cadence sensor serving to guard against undesirable actuation of either front or rear derailleur without necessary chain movement being present and additionally making use of a standard wireless remote control (RC) servo drive unit relying exclusively on spur gearing reduction facilitating highly efficient and accurate derailleur positioning thereof through a magnetic rotary encoder with direct sensing of derailleur position and with alignment of derailleur actuation components thereof in the horizontal plane guarding against undesirable transmission of gravitational and vertical inertial forces to wireless remote control (RC) servo drive unit adversely affecting accuracy.
