Shimano RT-MT800 Center Lock Brake Rotor for XT w/ Magnet + Internal Teeth

The XT RT-MT800 Brake Rotor with Magnet by Shimano - Superior heat dissipation also for E-Bikes

The RT-MT800 center lock brake rotor from the XT series comes with an internally toothed magnetic lockring for the Shimano EW-SS302 speed sensor. Thus, it is suited for e-bikes equipped with a DU-EP800, EP801 or EP600 motor and is intended for use on the rear wheel only. 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 RT-MT800's proven sandwich construction with an aluminium core between two layers of stainless steel ensures efficient heat dissipation via the integrated radiation fins.

Guidelines for Replacing E-bike Components:

Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

Technology:

Ice Tech FREEZA
Shimano Ice Technologies provide a fast heat dissipation at your disc brake. The brake pads are equipped with aluminium cooling fins. The brake rotor is constructed using a sandwich technique in which stainless steel encloses an aluminium core. The stainless steel on both flanks ensures long durability, the aluminium allows heat dissipation. FREEZA is the further development of the brake rotor, in which additional ribs in the aluminium provide even better heat compensation. This cooling technology creates consistently high performance and longer brake pad durability while reducing fading and brake noise.
