Shimano STEPS RT-EM910 Center Lock brake rotor - for E-bike brakes

The Shimano RT-EM910 brake rotor is an extremely powerful Center Lock brake rotor with an internal lockring, recommended for E-bikes with a Shimano STEPS drive. Using the Ice-Tech FREEZA sandwich composite, it significantly reduces heat development and thus ensures constant braking performance. The RT-EM910 can be used with numerous disc brakes and both organic and sintered pads. A magnet for the SM-DUE11 speed sensor for the rear wheel is included.

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.

Ice Tech FREEZA brake rotors show even less fading due to 40° C less heat development compared to SM-RT98. The three-layer sandwich construction consists of stainless steel flanks and an aluminium core with integrated cooling fins. The two-part structure with the aluminium spider dissipates the heat well. The dirt-repellent design extends the service life of the rotor and pads. A real eye-catcher is the sporty, aggressive high-tech design.
