The Wilson Ultra 100UL V4.0 tennis racket is the lightest version of the range while retaining outstanding power output while being very gentle on the arm. Perfect for the youngest who go from a junior racket to the adult version. Without a doubt, it is the most maneuverable model thanks to its ultra-light weight and excellent power-oriented performance. This version is recommended for beginner players who should not use a lot of weight and for players who exchange their junior tennis racket for the adult version, but need a weight that allows them to handle the racket in an agile but precise way. The Ultra 100UL V4 uses two mechanisms to increase power, compensating for the fact that it has less mass, on the one hand, an enlarged SWEET SPOT channel that increases power when hitting, and on the other, a system of CRUSH ZONE grommets that allow the strings to have more movement in the grommet, allowing the ball to remain longer on the sieve and the player to print more depth to his shots Her cosmetics are just as elegant as her older sisters with a matte finish that, depending on the angle at which the sun reflects its rays, shows a wide range of blues. You will have a lot of fun on the court with this racket.
