Shimano Slx / 105 SM-RT70 Disc Rotor

Shimano SLX / 105 SM-RT70 Disc Centerlock

The SM-RT70 Ice-Tech rotors (160, 180 and 203mm) have a sandwich structure of an aluminum core embedded in 2 stainless steel layers. The higher heat dissipation of the aluminum helps to reduce the surface temperature of the rotor by around 100 degrees Celsius. Optional Ice-Tech brake pads with aluminum cooling fins can reduce the brake pad surface temperature by another 50 degrees. The result is high stopping power and practically no signs of fading!
