The chainrings are hollow to save weight and drastically improve stiffness and aerodynamics. They ensure optimum power transfer and improved shifting performance.

Note:These are chainrings from different types (MA, MB, MD). For optimal shifting performance only use chainrings from the same type. So it is recommended to combine MA with MA, MB with MB and MD with MD.
