I am no aerodynamics expert, and maybe neither are Mercian :-) but surely the plate on the rear seat stays is less aerodynamic that normal seat stays?
yeah that was my thought, too. but the stays are ridiculously thin, so maybe it's for strength more than aerodynamics? i'm guessing that the seatpost already disrupts the airflow enough to not matter.
