The Wilson Ultra Team 23 Inch Junior Tennis Racket has been designed for boys and girls ages 7-8. They are best for beginner junior players who are new to tennis, but aspiring to become competitive in the near future. They have several technologies built into the frame which provide effortless power. It is a 23 inch long frame (27 is considered standard for an adult sized frame), the head size is 95 square inches (100 sq in. is also standard on most adult frames), and it weighs 8.5 ounces (adult frames are typically 9.5-12oz). The 16x17 string pattern allows for larger squares in the stringbed, and this helps "bite" more of the ball, which results in increased spin. The Ultra Team 23 features Power Rib with Integrated Cush Zone Technology, which are strategic frame shapes that increase energy return, while the special yoke grommet increases ball dwell time on the strings. Parallel Drilling enlarges the sweet spot in the string bed, while providing more power on off-centered shots. The clean, modern design uses bold color contrasts and turns heads on the court.
