Shimano ROTOR FOR DISC BRAKE, RT-EM810, S 160MM, W/LOCK RING (External Spline Type)

The Shimano RT-EM810 is a 160mm Center Lock disc brake rotor designed for Shimano STEPS e-bikes, with an integrated magnet that works with the STEPS speed sensor. Building the magnet into the rotor removes the need for a separate spoke magnet, keeping the wheel clean and the speed reading reliable. The rotor delivers consistent braking with XT-level construction suited to the added weight and speed of an e-bike. It includes an external spline lock ring for mounting to Center Lock hubs, and the 160mm size suits the rear of many e-mountain and e-trekking bikes.
