Bicycle Disc Brake Rotors (2pcs) for Road Bikes and Mountain Bikes. Lightweight, High-Speed Heat Dissipation Steel, High Hardness, 12 Bolts, Hollow

[Reduced Riding Load for Comfortable Riding] Dual disc brake rotors are manufactured with a lightweight design, minimizing the additional weight burden on the bicycle. This reduces the effort required when starting, reduces fatigue during long rides, and allows for smooth handling of mountain bike uphill riding and BMX agile maneuvers. [Excellent Heat Dissipation with Hollow Structure] The rotor body adopts a hollow design, significantly improving ventilation and increasing the rate of heat dissipation. Even during prolonged continuous braking (e.g., downhill riding), it prevents a decrease in braking force due to brake overheating, maintaining stable braking performance and enhancing riding safety. [High Hardness for Longer Lifespan] Made from high-quality steel, it boasts high hardness and toughness. It is highly resistant to wear from everyday friction and impact, significantly extending its service life. In addition, it has excellent wear resistance and corrosion resistance, allowing for stable long-term use even in adverse environments such as rain and muddy roads. [12 Bolts Included] The package includes 12 bolts, eliminating the need for additional special tools and making it easy to replace old brake rotors or damaged parts. Even first-time installers can complete the job quickly with simple operations, improving the convenience of maintenance. [160mm Size for Multiple Bike Types] With a standard 160mm diameter, it's a highly versatile design that fits not only mountain bikes and BMX (bicycles), but also road bikes. It comes in a pair, allowing simultaneous use on both the front and rear brake systems of your bicycle, and offers excellent cost performance when purchased in bulk.
