Enhanced 360° visibility of the biker via circular wheel reflection from all directions when illuminated. You'll be seen from all angles as the reflectors throw back light in all directions. The reflectors use a coating of aluminum on microscopic glass balls with fine and aesthetical design and fit nearly all spoke sizes and forms. They have no negative impact as the wheels still run perfectly true.
