2 Packs 140mm Stainless Steel Floating Disc Brake Rotors with 12 Bolts for Mountain and Road Bikes - Brake System Upgrade(Black)

High-strength materialOuter part uses high-strength stainless steel, inner part use 7075 ultralight thicken aluminum alloy material, machine marking, and stamping.Stiffness and lightweight.Special heat sinkThe inner and outer disc floating brakes use two different materials, which are connected to each other by rivets. While reducing heat transfer, it has a certain degree of freedom, on the other hand, it solves the problem of internal tension. Hollow deviseHigh-strength while reducing weight, and the hollow structure helps to dissipate heat, drain mud and drain.SPECIFICATIONProduct Name: Bike brake rotorColor: Black, RedRotor Dimension: 140mmCenter Distance: 44mm Thickness: 1.55mm ±0.05mmMaterial: Stainless steel + Aluminum alloyHub/Disc Compatibility: 6-Bolt Weight-140 mm rotor: About 85g/pcsFunction: reduce the weight of brake pads, improve appearance, reduce heat transferPackage Include: 2 x Disc Brake Rotor + 12 x Screws
