This is the "553 Driver," a distance-focused model from Golf Partner's original brand, "NEXGEN." The design incorporates two sole bars to increase the moment of inertia, making it less susceptible to distance loss on off-center hits. The trajectory is slightly high, allowing for carry distance while maintaining a strong, straight flight that resists wind. It's equipped with the N.S.PRO Regio Formula for NEXGEN Type S 65 (S flex). This is a mid-kick shaft that's stable even when swung hard, recommended for players with a head speed of 43 m/s or more.
