Disc brake rotor Shimano STEPS RT-EM910 180mm Ice-Tech Freeza external C-Lock

The Steps RT-EM910 E-Bike disc rotor from Shimano with Center-lock mount, ICE-TECH FREEZA technology and integrated magnet. SHIMANO RT-EM910 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 FREEZA – 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. The lightweight and highly efficient three-layer sandwich structure of stainless steel–aluminum–stainless steel enhances heat dissipation.

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.
