The Ultra 100L v4 offers a lighter alternative for players who want a more hand-friendly game without compromising on the ability to hit with speed and power. With a new construction and new geometry, the racket performs completely differently than previous rackets in the series. This frame, highlighted by the integration of FORTYFIVE°, provides a softer, more comfortable feel along with increased stability, improving the delivery of easy power for users. Key geometric updates also include an expanded Sweet Spot channel at the tip of the rim, which provides additional power and reduced weight, for a more elegant and aerodynamic look. When it comes to looks, this racket is second to none: changing colors through the angles of sunlight reflecting off the racket’s surface, creating a dazzling effect. Crush Zone - Innovative eyelet system compresses on impact, allowing the ball to stay on the string longer, providing a better feel and more potential energy to fuel explosive power.PARALLEL DRILLING  - Eyelet design provides consistent, more forgiving string response while significantly increasing the sweet spot.FORTYFIVE°  - Frame layout provides improved ball feel. The material increases both flexibility and stability without compromise.Sweet Spot Channel - A recess in the side of the frame extends the lateral strings and increases the movement of the guide for greater power.Agiplast - Plant-based grommets, guides and end caps reduce environmental impact.
