Newgoal Bicycle Brake Disc Mountain Bike Floating Brake Disc Center Lock Bicycle Accessories (Red 203mm)

• ①【High-quality materials】The bicycle brake disc is made of qualified aluminum alloy and stainless steel, which is corrosion-resistant, non-deformable and durable.
• ②【Good wear resistance and heat dissipation】 Mountain bike brake discs are colorful, beautifully designed, beautiful and elegant, good wear resistance, fast ventilation and good heat dissipation
• ③【Reduce The Heat Transfer】The 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
• ④【Good braking performance】 Do you want to get real and strong braking performance on the winding road in the active downhill mountain area? Then our 160mm 180mm 203mm brake discs fully meet your requirements
• ⑤【Easy installation】 It is easy to install on the finished brake disc frame and front fork. The perfect stainless steel bracket of the bicycle brake disc and the polished outer rotor provide high-quality equipment for the rider

description: If you use a high-speed brake or brake for a long time, the brake disc will bulge due to the intense friction caused by high temperature heat, the floating disc will be located outside the friction surface of the brake disc, and the internal bracket will be separated with a special For the non-rigid structure, see above. When the friction surface is thermally expanded, the friction surface and the fixture become relatively independent stressed surfaces. The floating structure gives the friction surface some free longitudinal and longitudinal expansion space, thereby eliminating the internal conditions of the friction surface. Therefore, the frictional surface will not be generated due to uneven heating caused by deformation, making the brake more stable and reliable. When a common disc, the high-temperature expansion of the outer edge and the lower part of the temperature are combined, a strong internal tension will be generated, which will seriously cause lateral deformation of the disc. feature: The brake disc is made of suitable aluminum alloy and stainless steel, corrosion-resistant, non-deformable and durable. Lightweight and can significantly reduce weight. The shape of the disc ensures good heat dissipation during heavy braking, reduces discoloration, warpage of the brake and ensures the life of the rotor. The floating system design can reduce the deformation of the belt at high temperatures and reduce the heat transfer to the hub. Ensure excellent braking performance.
