Shimano Steps RT-EM800 Ice-Tech Rotor – Black/Silver
RT-EM800 Ice Tech E-bike rotors with built in speed sensor magnet providing consistent braking performance through energy control. Uses revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while riding. The alloy clad steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 degrees, 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. Rotor houses the magnet necessary for speed sensor function on Shimano STEPS equipped E-bikes allowing frame clearance for wider tyres.
