Upgraded Floating Hydraulic Brake Rotor 180mm/160mm

About this Bike Rotor This rotor fits all BeeCool Models. One piece of the rotor is included in one order, so you need to buy two pieces if you want to replace both rotors on your bike.180mm rotor for Bee Adventurer/Explorer/Pathfinder/Challenger/Ranger/Voyager160mm rotor for Bee Tracer/Pacer/Blazer Why Do You Need A Floating Disc?The emergence of floating discs is to solve the problem of continuous frictional temperature rise of the discs, due to thermal expansion and contraction, if it is a one-piece disc, the temperature of the center and the edge of the disc will be different, and the degree of expansion will be different, generates internal tension, causes the disc to deform, and brake failure. Generally speaking, the floating disc is connected by rivets with two materials. This connection is non-rigid and has a certain amount of freedom. On the one hand, it reduces heat transfer and on the other hand, it solves the internal problem. Stress problem, so it is relatively stable. The
