Shimano STEPS RT-EM810 Center-Lock Disc Rotor for E-Bike
Product information "STEPS RT-EM810 Center-Lock Disc Rotor for E-Bike"
SHIMANO RT-EM810 disc brake rotors for speed sensor systems deliver powerful and consistent brake performance in all riding conditions. The ICE TECHNOLOGIES FREEZA rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. SHIMANO's CENTER LOCK mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

Technologies

ICE TECHNOLOGIES FREEZAICE TECHNOLOGIES combined with FREEZA disc brake rotor construction rapidly dissipates heat for more consistent braking performance in extreme conditions, longer pad life, and less brake fade and noise.
Benefits & Features
- Lightweight clad rotors with heat dissipating paint on exposed aluminum layer segments provide superior cooling, consistent brake performance, and lighter operation under all conditions.
- Clad brake pads with Aluminum/Stainless fins support rapid heat dissipation which helps reduce maintenance, provide longer pad life, and create less brake fade and noise.
- ICE TECHNOLOGIES and FREEZA provide consistent braking performance with longer pad life, less brake fade and noise.
- The lightweight and highly efficient three-layer sandwich structure of stainless steel–aluminum–stainless steel enhances heat dissipation.
The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
