Main benefits

The disc is intended for e-bikes and has a higher weight and speed, so that the braking performance remains reliable in various conditions.
ICE TECHNOLOGIES FREEZA cooling quickly dissipates heat, thus helping to limit brake wear and unnecessary noise.
The Center Lock attachment simplifies assembly and disassembly thanks to the grooved carrier and locking ring.
The integrated magnet supports the speed sensor, so the SHIMANO STEPS system works cleanly and without improvised accessories on the bike.

Technical parameters

The technical designation of the disc is RT-EM810 for SHIMANO STEPS systems.
The diameter of the brake disc is 203 mm for high braking effect.
The weight of the disc is 0.166 kg including the integrated magnet.
The sandwich material consists of stainless steel, aluminum and stainless steel.

Conclusion
