The RQiS series offers incredible snap-back action which stores energy on impact and then releases it with power and speed leading to a higher level of impact speed. CS Carbon Nanotube has been adopted to further increase the impact speed. Racquet choice of Lleyton Hewitt, the RQiS 1 is a mid-sized RQ Tour model which helps players produce winners.

Impact Speed: A snap-back action which stores energy on impact, then releases it with tremendous power and speed. The new material, Cup-Stack Carbon Nanotube, was adopted in these racquets to lead the ball to accelerate faster on each serve or return shot.

Cup-Stack Carbon Nanotube: Incorporated into the racquet frame, it provides all players the right amount of flex to stay with the ball and quick repulsion to make the full energy available for powerful returns.

Elastic Ti: Elastic Ti delivers the performance players have long wanted in a frame - high elasticity and high strength together. Titanium fibers in the shaft flex and snap back to their original shape a split second after impact and deflection with high accuracy and the with the full energy of the swing. It provides enhanced feel and an ultra efficient energy transfer.

Isometric Head Shape: Allows for more strings of equal length and a larger effective hitting area in the stringbed. Power, control and a huge sweet spot without increasing frame dimensions. With more strings of equal length and a larger effective hitting area in the string bed, it provides consistently more accurate shots with more power and control.
