Stainless steel brake disc reinforcement material, decontamination and drainage design, high-strength material, stainless steel floating buckle. Hole distance international standard 44mmPrecision manufacturing, stamping forming, high hardness. Anodized, No Rust, Hollow Out, New Upgrade, Polished, Good Corrosion Resistance, Increased StrengthStainless steel material, tensile strength, not easy to deform, toughness, reinforced corner design, with better tensile strength and shock absorptionHigh strength, CNC turning, lightweight hollow design, good heat dissipation performance, colorful electroplating process, mirror polished surface.The hollow edge design significantly and effectively increases the air contact area, accelerates the heat dissipation of the disc, and at the same time brings excellent weight reduction effect, and also helps the rapid discharge of sediment and rainwaterThe oblique and long hollow design, the hollow edge increases the friction coefficient of the disc, and even the low-end wire-pulling disc brake can be matched with a good braking effectThe multi-spoke foot design ensures the stability and durability of the disc, and reduces deflection and deformation.Good friction performance, one-way dense grinding, stable friction coefficient, ensuring durable and stablePerfect circle design, compatible with various brakes, to ensure maximum friction area, highly fit friction brakes, and prolong service lifesize:160mmMaterial:Stainless steelcolour:As ShownPackage Contents:1 * HS1-160mm Bicycle Brake Disc1 set * screwsOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
