Shimano SM-RT70 140 disc, 203mm

Shimano SM-RT70 140 and 203mm disc

Shimano SM-RT70 is a Center-Lock brake disc with Ice-Technology. This means it's made of a sandwich composite of two layers of stainless steel surrounding an inner layer of aluminum. This ensures excellent heat dissipation even on long descents and challenging trails. The SM-RT70 rotor is recommended for the new SLX brakes, but is also compatible with other models.

Technologies

Ice-Tech
Ice Technology allows for rapid heat dissipation from your disc brake. The brake pads are equipped with aluminum cooling fins. The brake disc has a three-layer sandwich structure, with stainless steel surrounding an aluminum core. The stainless steel on both sides guarantees long-lasting durability, while the aluminum ensures good heat dissipation.
