Abstract
A bicycle rear derailleur is basically provided with a base member, a cable operated structure, a movable member and a biasing member. The movable member is movably supported to the base member by the cable operated structure to move between a plurality of shift stage positions with respect to the base member. The biasing member is interposed between the first and second link members such that the movable member is biased towards one of a top shift stage position and a low shift stage position. The cable operated structure and the biasing member configured balance an operation energy used for shifting between each of the shift stage positions.
