Features1Superior Heat Dissipation: Featuring a unique hollow design, this disk brake significantly enhances air circulation. It efficiently dissipates heat even during long descents or high strength braking scenarios, reducing brake fade and ensuring consistent braking performance. This results in a smoother and more secure riding experience. 2Wide Compatibility: Designed for a variety of vehicles, this electric scooter brake disc replacement is compatible with multiple braking systems. Whether youre using an electric assist scooter, or a traditional cycling, it can be easily installed to instantly elevate the overall braking performance of your vehicle. 3SUS410 Stainless Steel Construction: Crafted from SUS410 stainless steel and undergoes meticulous quenching processes, this electric scooter brake disc exhibits remarkable strength and durability. It maintains its structural integrity even under extreme braking conditions, enhancing longevity and providing good performance. 4CNC Fine Machining: Through advanced CNC machining, the contacting area of the scooter skateboard brake discs friction surfaces is enlarged for good alignment with brake pads. This ensures responsive braking action with every application. Additionally, a slick surfaces treatment minimizes brake noise, contributing to a quieter ride. 5Reinforced Thickness: Specifically upgraded to a thickness of 2.3mm for vehicles like electric scooter that require superior braking force, this design provides enhanced support and resistant to twisting. Even under heavy loads or at high speeds, the braking effect remains good, further guaranteeing rider safety during all conditions.SpecificationItem Type: Disc Brake Material: Stainless SteelSize: Approx. 203mm / 7.99in, Thickness: Approx. 2.3mm / 0.09inPackage List1 x Disc Brake6 x Screws
