HEAD 采用了最新的微凝胶技术升级了最广受欢迎的Radical 系列球拍。Microgel材料置于拍框内部并遍布整个拍面。 HEAD updates its ever popular Radical line with MicroGel technology. The MicroGel material is included inthe frame construction and placed all the way around the head of the racquet. HEAD states that when combined with carbon composite fibers in the racquet head, the MicroGel deforms and compresses upon ball impact, uniformly absorbing and distributing the impact load around the entire frame. According to HEAD, MicroGel creates a rock-solid feel and improved comfort while offering extra stability against twisting.
