Prince Speedport Black
- as used by the Bryan Brothers
From the very first shot you will find a large sweetspot and a forgiving feel from the Speedport Black. The open 16/19 string pattern provides excellent spin. With the Prince O3 Speedport technology, there's a lot of comfort with every hit and a softer, dampened feel at impact. Thanks to a new grommet system, called the Speed Port Tuning System, you can fine tune the feel of the O3 Speedport Black.
Two grommet systems come with the racquet (both black). One system, the String Port insert, acts like a regular Speedport racquet, allowing the strings freedom of movement. The other grommet system, the String Hole insert features a standard grommet to restrict string movement (like a regular grommet system) without altering the aerodynamic benefits of the large Speedports. With the String Hole insert, you will notice better feel from the racquet. With the String Port insert, more comfort and vibration dampening.
The Speedport Tuning System can be switched each time you get a restring and does not alter the overall specifications of the racquet. |
