Yonex Arcsaber lite is part of the Arcsaber series. The ARCSABER frame is designed to flex at the point of impact to hold the shuttle on the string bed for longer. By storing and then releasing energy, ARCSABER delivers precise shot-making for players seeking a higher level of control. Nano air Spring in the resin binds the carbon fibers so that nano scale air bubbles in the material help the racquet to flex and bend as in a spring. the result is a better transfer of energy from string-bed to shuttle for a more powerful hit. The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions. NANOAIR SPRING provides excellent control, accuracy and power.
