While shortening the shaft significantly improves impact accuracy and straightness, it also introduces drawbacks such as changes in swing feel, increased shaft stiffness, and difficulty getting the ball airborne. The Speeder SLK utilizes the latest technology to overcome these disadvantages.\u003c\/p\u003e\u003cp\u003eFirst, by adopting Metal Composite Technology (MCT), which combines carbon and metal, it achieves a club balance that is typical even with standard head weights (around 200g). This allows the shaft to maintain the same swing feel even when shortened, making it possible to achieve a head-heavy balance without increasing tip rigidity.\u003c\/p\u003e\u003cp\u003eAdditionally, multi-hoop ply lamination technology is used to laminate multiple hoop layers in the butt section to make it easier to feel the shaft's movement. This allows for increased tip speed without feeling stiff. Furthermore, a high-torque design ensures that the torque does not become too tight, resulting in good ball capture.\u003c\/p\u003e\u003cp\u003eTo counteract the reduction in launch height and clubhead speed caused by shortening the shaft, the vibration frequency is set to be softer. This enables high trajectories and stable shots. Moreover, the increased diameter of the grip section prevents excessive force from being applied by the right hand, providing a natural swing feel.\u003c\/p\u003e\u003cp\u003eThe Speeder SLK is a golf shaft designed to maintain the lively swing feel of the Speeder series while maximizing the benefits of a shorter shaft.\u003c\/p\u003e\u003cp\u003e\u003cspecs\u003e\u003c\/specs\u003e\u003c\/p\u003e\u003cp\u003eProduct Name: PRGR RS Driver (2026 Model)\u003c\/p\u003e\u003cp\u003eFace Structure: 4-layer composite
