RT-EM810 Centerlock Disc Brake Rotor

Product Information

The Shimano RT-EM810 Centerlock Disc Brake Rotor is engineered specifically for the demands of e-bikes, where higher system weight and speeds generate significant heat. This rotor leverages Shimano's advanced Ice Technologies FREEZA design to effectively manage heat, ensuring consistent, powerful braking performance even on long descents. Its two-piece construction, combining stainless steel and an aluminum core, actively dissipates heat, prolonging pad life and reducing fade.

This rotor is a smart upgrade for e-bike riders seeking reliable and durable stopping power. It’s designed for rear wheel installation and integrates a magnet for seamless compatibility with Shimano STEPS speed sensor systems, making it a tailored solution for modern e-bike setups.
