RSL

Model no. Diamond X3 Gold Shaft 7mm Weight 86-88g Lenght 675mm Max. String Tension High Tension Up To 28lbs Features Extender Stage 2 The EXtender Stage 2 was reengineered from Stage 1 especially for  Diamond X3 to work at its best with the Pulse Technology. The Pulse  technology gives X2 one of the strongest head frame in the market,  and with the new EXtender Stage 2 design we manage to keep the strength of the frame but injecting much more power into what is already an incredible racket. Diamond PULSE Technology No more Frame Deformation No more High string tension failure No more Incorrect stringing tension No more Lossing string tension overtime Poly-Matrix Carbon This is a new technology to combine different layers of Structural Carbon  and High Modulus Carbon together. It results in 19% more strength to our  high tension frame. This means better power transfer and more accuracy  during impact. Anti Twist Technology With the new Super High Modulus Multi-Layered Graphite, it is important to get the ingredient right. Too much = Too Brittle Too little = too weak to transfer the Power to impact. With the right amount on RSL shafts it will give Super Durability, Flex Power and Stop Shaft Twisting. Super Strong High Tension Frame Super High Modulus Multi-Layered Graphite Construction means High Tension Frame when stringing and able to substain impact in double play. Flex Power Flex Power is RSL's latest Technology by combining the characteristics  of the Frame Design, Thin Flexible Shaft and matching it with the perfect Balance Point to give you Super Power from a light weight frame. Super Thin Shaft With the Super High Modulus multi-Layered Graphite Construction,  our Shafts can be thinner which means a reduction in weight and increase in flexibility but still with Superior Strength and Durability.
