A cool innovation.
Shimano's SM-RT86 Ice-Tech Disc Rotors feature a unique 3-layer construction that allows them to operate up to 220 degrees (F) cooler than standard steel rotors. They're built with aluminum core and two stainless steel outer layers to lower the operating temperature, resist power fade and increase pad life. Optimized for Ice-Tech brake pads. For use with standard 6-bolt hubs. Available in 160mm and 180mm sizes. Actual weight: 114g (160mm, weighed without included hardware). Sold individually.
