Prince debuts the new Speedport Tuning System with this racquet. This is a revolutionary new racquet technology that enables players to fine-tune the feel of their racquet without changing strings or tensions. The secret is in the grommets. This new frame comes with two sets of very different plastic grommets. One set is a traditional grommet with constricting holes that hold the string in place providing a classic feel. The second set is an O-port grommet that allows the string more movement thereby enhancing the sweet spot and shock dampening. Prince recommends trying both sets of grommets to determine which suits your game better. | Specifications for: Prince O3 Speedport Tour
