The TRPX iron shaft I-50 to I-100 series is an innovative shaft that further clarifies the conventional model's "performance flow design," optimizing the distribution of impact-resistant and high-flex materials according to weight. The lightweight 50g-class shafts use more impact-resistant material to increase ball speed while achieving high launch and high repulsion performance. As the weight increases from the mid-light to heavy range, the proportion of high-flex material is increased, allowing for precise control of launch angle and distance.
This design allows beginners to easily achieve high launch angles and longer distances, while advanced players can achieve both precise distance adjustment and launch angle control. Available as a 4-piece set from #7 to #W, it can accommodate everything from single shaft replacement to multi-shaft customization. Made from carbon material, it is lightweight yet highly durable, ensuring stability during rounds. TRPX's unique technology minimizes swing deviation and maximizes shot accuracy.
Furthermore, the performance flow design is optimized to match the swing characteristics of golfers in each weight range, comprehensively improving distance, trajectory, and operability. It provides stable performance in all situations, regardless of the golfer's skill level.
