Apparatus for retaining a brake drum to a fastening bracket

A bicycle hub brake component is provided for braking a hub (6a) of a wheel mounted on a bicycle frame (1). The component comprises a fastening bracket (30f, 30r) that has a first surface and a second surface opposite the first surface, wherein the fastening bracket (30f, 30r) is adapted to be nonrotatably mounted to the frame (1). A brake drum (40) is adapted to rotate integrally with the hub (6a), wherein the brake drum (40) has a brake face (51a) on an inner peripheral surface thereof and a convex portion (44e) adapted to face the first surface of the fastening bracket (30f, 30r). A bracket retaining component (36, 37) is removably mounted to the fastening bracket (30f, 30r) and extends diametrically so as to engage the convex portion (44e) to help prevent the brake drum (40) from detaching from the fastening bracket (30f, 30r).
