A bicycle rear derailleur (12) includes a base member (20), a movable member (22), a chain cage (90,94), a first pulley (92), a second pulley (96) and a chain guard member (98). The base member (20) is configured to be mounted to a bicycle. The movable member (22) is movably coupled to the base member (20). The chain cage (90,94) is coupled to the movable member (22) to move between at least a first orientation and a second orientation. The first pulley (92) is rotatably mounted relative to the movable member (22). The second pulley (96) is rotatably mounted to the chain cage (90,94) to move with the chain cage (90,94) relative. The chain guard member (98) is movably coupled relative to the movable member (22). The chain cage (90,94) includes an engagement portion (106) arranged to move the chain guard member (98) from a first position to a second position when the chain cage (90,94) is moved from the first orientation to the second orientation. |
