Features: 1The interior is made of ultra-light and thick aluminum alloy material, with unique heat dissipation design, better heat dissipation capacity, higher strength and hardness. 2Full CNC engraving and milling, anodizing treatment, stamping and forming, reducing the weight. 3Special structure of the heat sink is added. After the heat treatment process, the plate is in continuous contact with the outer frame, which is equivalent to a heat sink, and the heat can be quickly dissipated. 4The thickness of the brake pad is 1.8mm, and the middle of the heat dissipation floating disc is thickened to 3mm. 5Stainless steel floating buckle design makes the outer disc not directly locked with the hub, leaving room for expansion. 6Five?hole 75 fixed connection design is the most stable form of force, which can avoid vibration caused by the longitudinal expansion of the high?temperature brake disc during braking. Package included: 1 x&nbspHeat&nbspDissipation&nbspFloating&nbspBike&nbspRotor
