Zusammenfassung:	An electronic derailleur control system for a bicycle has controller operatively connected to a derailleur of the bicycle and to at least one sensor of the bicycle, and a memory on which instructions are stored that are executable by the controller to control shifts of the derailleur. The system is receives feedback data from the sensor on a performance parameter of the bicycle, and analyzes the feedback data to evaluate performance conditions. The controller calculates adjustments to the derailleur shifts based on the performance conditions, with automatic iteration to repeatedly accept feedback and optimize the shift distance based on the feedback. The system can be activated by rider command or by satisfaction of pre-set performance conditions stored in the memory. A derailleur and a method for controlling shifts on this basis also are disclosed.
