The Shimano RT-MT800 Steps Rotor with Lockring and Magnet is built with an in speed sensor magnet providing consistent braking performance through energy control. It uses revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while riding. The 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 Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round. Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion....
