Shimano SM-RT76 Deore XT 6 Bolt Rotor The Shimano SM-RT76 Deore XT brings 2-piece rotor construction to the masses with an innovative design trickled down from XTR. The two-piece rotor is lighter, stays cooler, and resists warping better than previous versions. The SM-RT76's aluminum spider saves weight, dissipates heat like a champ, and increases overall stiffness while the steel construction rotor resists wear for the long haul. A cooler rotor means better braking performance and less chance of brake performance suffering in sections that you're applying the brakes heavily. The Shimano SM-RT76 Deore XT 6 bolt rotor is an undeniable workhorse and will help ensure that braking performance is at optimum levels at all times.
