They have a two-piece floating design, consisting of a laser-cut 410 stainless steel outer braking surface riveted to a CNC machined aluminum center. This floating design allows the outer steel surface to expand separately from the aluminum center to handle high temperatures without warping. The rotor's true floating design provides one degree of freedom, letting the outer section expand when heated while self-centering to reduce drag.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv id=\"seqbpdescription-3\"\u003e\u003cp\u003eThe aluminum center is stiff yet lightweight, offering the benefits of a thicker fixed disc without added weight, and also acts as a heat sink to keep disc temperatures lower for consistent braking. The stainless steel braking surface is laser-cut and heat-treated for increased durability and oxidation resistance. The machined round outer edge enhances safety and makes wheel changes easier.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv id=\"seqbpdescription-4\"\u003e\u003cp\u003eBoth rotors have a thickness of 1.8mm (with a minimum thickness of 1.5mm), weigh 121 grams each, and are compatible with all pad compounds.
