Since "weight weenie" cyclists often shop for components based on
catalog weights, a disc rotor with holes will have a competitive
advantage of a disc without. In addition, the holes catch the eye as a
perceived improvement over plain disc rotors, since the holes are an
added "feature". No engineering involved, just marketing.
