1Hollow Design: The bike disc brake rotor features a large area of hollow design, significantly reducing weight and increasing the air contact area, enhancing heat dissipation of the brake disc. 2Stainless Steel Material: Made from stainless steel, the 160mm bicycle disc brake rotor offers anticorrosion and rustproof resistance, high strength, and is less prone to deformation. 36 Hole: Designed with 6 hole fixed connection, it provides the most stable force transmission. The floating structure prevents vibration caused by longitudinal expansion of the brake disc during high temperature braking, enhancing cycling safety. 4Improved Stopping Power: With the disc brake system, you can expect enhanced stopping power and better control over your bike, giving you confidence on any terrain. 5Easy Installation: The disc brake kit is easy to install, allowing for hassle free setup and replacement, providing optimal braking performance.
