Shimano 180mm Disc Brake Rotor RT-EM600

SHIMANO RT-EM600 disc brake rotors for speed sensor systems provide consistent and powerful braking on rugged mountain bike trails. The robust and durable ICE TECHNOLOGIES rotors 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.
