The Ultra 100 v4 ushers in a new generation of Ultra with supreme style and invigorating performance. Thanks to a new construction and a new geometry, this racket plays unlike any Ultra before it. Highlighted by the integration of FORTYFIVE° into the lay-up for a softer, more comfortable feel along with enhanced stability, this frame upgrades the delivery of easy power for its users. Key geometrical updates include an expanded Sweet Spot Channel at the tip of the hoop for extra power and reduced bulk in the beams for a sleeker, more aerodynamic look. On the subject of looks, this racket has no rival: color-shifting blues dance to the different angles of sun rays deflecting off the racket surface for a dazzling display.
