Abstract
A bicycle derailleur assembly includes a base member, an intermediate member, and a movable member supporting a chain guide. The intermediate member is coupled to the base member for pivoting relative to the base member around a pivot area defining a pivot axis, and the movable member is coupled for movement relative to the intermediate member. A cable guide roller having a cable guide surface is provided to the derailleur assembly, wherein the cable guide surface intersects the pivot area when viewed in a direction of the pivot axis.
