RT-EM900 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. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 degrees, this provides great improvements in performance all round.
Freeza rotors allow the alloy core to extend out from the braking surface as a fin to providing added cooling. 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.
