The O³ Speed Port Black is up to 24% more aerodynamic through advanced engineering so your racquet is faster and more stable. A new Speedport Tuning System (STS) allows you to customize your racquet to your swing style.
The Speedport Black is the racquet of choice for World No.1 doubles team, Bob & Mike Bryan. With a low power level, this racquet is best suited to players with a fast and long swing type. The O³ Speedport Black is one of the best all-around racquets for an intermediate to advanced player with a fast and long swing speed.
Every O³ Speedport Black comes with two sets of grommet inserts, a string port insert and a string hole insert.
This racquet is prestrung with Prince Synthetic Gut Duraflex 16 White using the port insert. The hole insert is included.
Speedport Tuning System:
Fine-tune the feel of your racquet with the Speedport Tuning System (STS) - an exclusive Prince innovation which allows players to match the sound and feel of the racquet to their playing style and preference. This system allows customization of the port inserts in the frame at 3, 9, and 12 o'clock positions. Every O³ Speedport Black comes with two sets of grommet inserts, a string port insert and a string hole insert. Choose the String Port Insert for a softer feel with improved string damping. Or, for a firmer feel with increased string feedback, choose the String Hole Insert. The String Port insert is installed from the factory and can be switched during stringing and does not alter the specs of the racquet.
O³ Technology: Prince has once again revolutionized the art of racquet design with the launch of the O³, a breakthrough in racquet engineering that allows you to hit your best shots more often.
By replacing the traditional pin-sized string holes with giant Speedports that provide total string freedom of movement the sweetspot size is increased up to 59%, which means you hit your best shots more often. What's truly impressive is that Prince did it all without enlarging the racquet head, increasing its length, or adding weight. So it's easy to maneuver and quicker through the air.
