1. A bicycle derailleur comprising:

  • a base member adapted to be mounted to a bicycle;

    a movable member movably coupled to the base member;

    a chain guide coupled to the movable member for rotation around a rotational axis;

    a resistance applying element that applies resistance to rotational movement of the chain guide;

    a resistance control element that moves between at least a first position and a different second position;

    wherein the resistance control element comprises a lever that operates the resistance applying element;

    wherein the lever is disposed at the derailleur;

    wherein the resistance control element is operatively coupled to the resistance applying element so that the resistance applying element applies a first resistance to rotational movement of the chain guide when the resistance control element is disposed in the first position and so that the resistance applying element applies a different second resistance to rotational movement of the chain guide when the resistance control element is disposed in the second position.
