The Shimano XT SM-RT86 Ice-Tech 6 Bolts Disc Brake Rotor is infused with proven Ice-Tech braking technology, trickled down from the top-end XTR group. Ice-Tech is a technology that blends the durability of a stopping power of a steel rotor with the heat dissipation properties of aluminium.
By sandwiching an Aluminium cooling core between two steel braking surfaces, the rotor dissipates heat faster, while the steel outer portion provides solid stopping power and a durable braking surface.
The two-piece "floating" rotor arrangement also saves weight and increases system stiffness, giving you the intense braking power you need, with the reliability and survivability that Shimano is best known for.
