The Shimano RT-EM910 eBike Centerlock Internal Serration Disc Brake Rotor is a super high performing eMTB rotor that is purposely made to work with Shimano's STEPS System. They deliver very powerful and consistent braking performance in all riding conditions by using 'Shimano's Ice-Technologies Freeza' feature that greatly improves heat dissipation. This ensures consistent, fade-free performance braking even on the steepest and longest downhill stretches. They even have a cleverly placed Speed Sensor Magnet to trigger the STEPS system so you can be sure to have accurate data one your STEPS display.
