Shimano RT-EM910 Center Lock Brake Rotor for STEPS w/ External Teeth

Shimano Center Lock brake rotor RT-EM910 - constant power for STEPS

The Shimano RT-EM910 Center Lock brake rotor is designed for e-bike riders with STEPS motors who demand maximum braking performance and heat control. Thanks to the Ice-Tech FREEZA sandwich composite, the RT-EM910 perfectly dissipates the resulting heat, contributing to constant performance even on steep descents. The brake rotor has a lockring with external teeth and comes with a magnet for the SM-DUE11 or EW-SS301 rear wheel speed sensor. It can be used with numerous disc brakes and both organic and sintered pads.

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.
