Specially modified graphene in the friction compound greatly improves braking performance, durability and heat transfer to the backplate Backplates are entirely covered in graphene heat dissipating coating to achieve much greater heat transfer from the friction material to the cooling fins and at the same time Patented angled radiator fins for superior airflow and cooling\nProvides predictability, power, better modulation and faster stopping Extraordinarily quiet even during long descents Third party online retailers must be preapproved by manufacturer
