Тhe Formula 2-piece disc is a revolution in disc brake technology. Similar to the one-piece disc, the steel braking surface has been tested and optimized to manage thermal expansion and ensure even pad wear. The innovation lies in how the aluminum spider is connected to the outer steel ring. Unlike any other hydraulic brake disc on the market, Formula's 2-piece disk can accommodate radial expansion caused by high temperatures, thanks to the design of the forged and CNC-machined inner spider body. With recent improvements, Formula has created a uniquely performing disc that extends the life of the pads and provides better cooling. Last but not least, the disc's lightweight design is noteworthy, weighing just 78 grams.
