The Diadem Nova 105 Lite rackets are Diadem's first over size frames. After years of experimenting we have created the ultimate combination of a high end with function. These user-friendly and extremely forgiving 105 square inch head combines excellent stability and created the World's most comfortable sweet spot. Flex Stabilization System (FS) is the first technology to utilize patent pending rib structure in the frame that combines high density foam and HMT Carbon, strategically placed to create a stable and powerful frame with superior feel. They come with a 16x19 string pattern and 105 square inch head to create a comfortable sweet spot with explosive power. The 105L are ideal for players looking for a lot of help from their racket, just swing and let it do the rest!
