Features

SHIMANO RT-EM910 disc brake rotors for speed sensor systems provide powerful and consistent braking performance in all driving conditions. FREEZA TECHNOLOGIES' compact, lightweight ICE rotors dramatically reduce heat build-up in the braking system to ensure consistent high-performance braking even on the steepest downhill grades. The CENTER LOCK mounting system from SHIMANO allows the rotors to be installed and removed quickly and easily with the spine bracket and locking ring.
