Avenger A4 EVO Frame uses a combination of silicone and wax casting technology. For small and sharp parts that cannot be achieved by EPS, instead use the molding process of casting wax. Make each piece of carbon fiber fit more smoothly and reduce wrinkles during the lay-up materials or molding process. At the same time, remove excess fillers from every corner, reducing weight by 80-100g compared to the previous generation. With the help of Toray's original T800 ,T1000 carbon fiber, the stiffness of the bottom bracket has been increased by 5%.
