Brake rotor for e-bikes with Center Lock mounting, 203 mm diameter and a magnet for the speed sensor; ICE TECHNOLOGIES FREEZA cooling.



When an e-bike speeds downhill, you want your brakes to be calm and controllable. The Shimano Deore XT RT-EM810 CL 203 mm brake rotor with magnet keeps performance stable even during long braking.

Main benefits

The rotor is designed for e-bikes and accounts for higher weight and speed, so braking performance remains confident in various conditions.

ICE TECHNOLOGIES FREEZA cooling quickly dissipates heat, helping to reduce brake fade and unnecessary noise.

Center Lock mounting simplifies installation and removal thanks to the splined carrier and lock ring.

The integrated magnet supports the speed sensor, so the SHIMANO STEPS system works cleanly and without improvised additions to the bike.

Technical parameters

The technical designation of the rotor is RT-EM810 for SHIMANO STEPS systems.

The brake rotor diameter is 203 mm for high braking effect.

The rotor weight is 0.166 kg including the integrated magnet.

The sandwich material consists of stainless steel, aluminum, and stainless steel.

Conclusion

The RT-EM810 is a brake rotor for riders who want stable braking on an e-bike even on longer descents. Thanks to cooling and thoughtful mounting, the bike feels calmer when braking. The magnet in the rotor also keeps the speed sensing elegantly integrated.
