Shimano RT-EM810 Disc Brake Rotor

This rotor is specifically engineered for electric bicycles and includes an integrated speed sensor magnet. While it will physically mount to standard Centerlock hubs, the speed sensor feature is only functional if your e-bike system is designed to utilize it.

The radiator fins significantly increase the surface area of the rotor, allowing it to dissipate heat much faster than a standard solid disc. This prevents brake fade during long, steep descents where e-bikes, being heavier and faster, generate more thermal energy.

Yes, the RT-EM810 is compatible with all brake pad compounds, including resin, metal, and semi-metallic. However, keep in mind that the rotor's narrow profile design is optimized for consistent performance across all these materials.

Yes, because it uses a Centerlock mounting system, you will need a standard external-bottom-bracket tool or a cassette lockring tool to tighten the lockring. It is a straightforward process, but you must ensure you have the correct tool on hand.

The 160mm size is a standard diameter for many e-bike rear setups, focusing on a balance between weight savings and stopping power. If your bike frame or fork requires a larger rotor for the front, you may need to look for a different size or use an adapter, though this specific model is currently offered in this configuration.
