More power. More comfort. More eco-friendly. Ultra v4 incorporates FORTYFIVE° technology strategically into the frame for enhanced stability and more comfortable feel throughout the swing. Equipped with a sleeker geometry, this version of Ultra upgrades access to easy power in a revolutionary color-shifting design that is as beautiful as the racket is dangerous. Pros often customize the racket they use. Racket specifications on endorsed consumer models may vary from the models used by Pros for match-play. The Ultra 100L v4 provides a lighter alternative for players who want more arm-friendly playability without compromising the ability to hit with pace and depth. Sporting a stunning design that spans an array of color-shifting blues depending how the light hits the frame, this racket matches its captivating looks with killer performance. An all-new construction features FORTYFIVE° for increased stability and comfort through the swing, an all-new geometry expands the Sweet Spot Channel for additional power and reduces bulk in the beam for a smoother, more ergonomic design, and plant-based bumper, grommet and end cap components make this a winner off the court as a more sustainable solution.
