The RT-MT800 centre-lock brake rotor from the XT series has an internally toothed magnetic lockring for the Shimano EW-SS302 speed sensor. This makes it suitable for e-bikes with a DU-EP800, EP801 or EP600 motor and is only intended for use on the rear wheel. Thanks to FREEZA Ice Technology heat dissipation, the temperatures that occur during braking are significantly reduced, resulting in more consistent braking performance. The service life of the brake pads is also extended. The proven sandwich construction of the RT-MT800 with an aluminium core between two stainless steel layers ensures efficient heat dissipation via the integrated radiant fins.
