<p>A bicycle rear derailleur (12) is basically provided with a base member (32), a cable operated structure (34, 36), a movable member (38) and a biasing member (46). The movable member(38) is movably supported to the base member (32) by the cable operated structure (34, 36) to move between a plurality of shift stage positions with respect to the base member (32). The biasing member (46) is interposed between the first and second link members such that the movable member (38) is biased towards one of a top shift stage position and a low shift stage position. The cable operated structure (34, 36) and the biasing member (46) configured balance an operation energy used for shifting between each of the shift stage positions.</p> |
