Sm rt86 ice tec rotors give excellent performance made from a stainless steel alloy 3 layer sandwich construction that manages heat while ridingthe clad steel alloy steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg c when used with ice tec pads surface temperatures can drop from around 400 to 300 deg c this provides great improvements in performance all roundice tec rotors achieve
