Raw Material

Stainless Steel：The 420J2 stainless steel imported from Japan, known for its excellent wear resistance and corrosion resistance. 420J2 has an even higher carbon content, hardness, and strength compared to SUS420J1. As the temperature of the brake disc increases, its ductility and durability also improve, thereby enhancing safety during braking.

Aluminum：We utilize 6061 aluminum imported from Switzerland, renowned for its high strength and lightweight characteristics, making it an ideal material for meeting the demands of high-performance brake systems. Since brake discs generate high temperatures during the braking process, the excellent heat conductivity of 6061 aluminum contributes to rapid heat dissipation and effectively reduces unsprung weight, maintaining the stability of the brake system. It is well-suited for riders who seek high performance and superior handling. Unsprung Weight
