Product Description Shimano SM-RT70 Center Lock brake rotor for SLX - Ice-Tech sandwich The Shimano SM-RT70 is a center lock brake rotor with Ice-Tech technology. This means that the sandwich composite consists of two stainless steel layers with an internal aluminium layer. This ensures excellent heat dissipation even on long descents and difficult trails. The SM-RT70 rotor is recommended for newer SLX brakes, but is also compatible with other models.
