Specially modified graphene in the friction compound greatly improves braking performance, durability and heat transfer to the backplate.Features: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 timePatented angled radiator fins for superior airflow and coolingProvides predictability, power, better modulation and faster stoppingExtraordinarily quiet even during long descendsShimano (K-type 2-piston) M9110/M9100/M8110/M7110/R9270/R9170/R8170/R8070/R7170/R7070/R4770/RS405/RX820/RX810/RX400/RS305
