A bicycle hub brake component is provided for braking a hub of a wheel mounted
on a bicycle frame. The component comprises a brake drum adapted to rotate integrally
with the hub, and a brake shoe. The brake drum has a brake face on an inner peripheral
surface thereof, and the brake shoe has a contact surface that contacts the brake
face of the brake drum to apply a braking force to the brake drum. A grease groove
is formed in the brake face of the brake drum, wherein the grease groove is aligned
between side edges of the contact surface of the brake shoe.
