Shimano RT-EM810 Center Lock brake rotor - for E-Bikes with STEPS

Shimano has designed the RT-EM810 brake rotor especially for the use on e-bikes equipped with a STEPS motor. It comes with a magnet for the SM-DUE11 speed sensor for the rear wheel and a lock ring with classic internal teeth. The brake rotor is compatible with various disc brakes and with both sintered and organic pads. Due to the Ice Technology with sandwich structure, brake fade is obviated.

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.

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, specially coated ribs in the aluminium of the rotor ensure even better heat compensation. This cooling technology creates consistently high performance and longer brake pad durability while reducing fading and brake noise.
