The SM-RT30 Brake Rotor with Magnet by Shimano - Affordable, e-bike-compatible model

The SM-RT30 is an affordable Altus-level center lock brake rotor that comes with an internally toothed magnetic lockring for the Shimano EW-SS302 speed sensor. It is therefore suitable for touring, city and MTB e-bikes equipped with DU-EP800, EP801 or EP600 motors and is only intended for use on the rear wheel. The brake rotor is based on a 2-piece stainless steel construction with stainless steel spider and can only be used in combination with organic brake pads.
