Named after the crystal steel molecules, the Cubiq® brake rotor combines state-of-the-art technology with modern design. Rotor shape promotes uniform brake pad wear - the same contact surface between the pad and disc every revolution generates regular wear. Less unsprung weight (up to 40% lighter than standard round rotors) reduces gyroscopic effect and improves the manueverability of the motorcycle. Increased perimeter surface design generates more cooling surface around the rotor for better temperature dissipation. Available in fixed (solid mount) or floating designs. Sold each. NOTE: For maximum braking performance and rotor longevity, Galfer recommends using Galfer brake pads with Galfer rotors.
