Product description
Understanding Tempo
Tempo is not about swing speed, but how you swing fast. It influences how you load and unload the shaft, which directly affects performance. Golfers with a quicker backswing and aggressive transition have a faster tempo, while those with a slower, smoother transition play with a more deliberate tempo. Matching tempo with the right shaft ensures optimal feel and stability.
Trajectory: Medium Flight
Trajectory refers to the height and flight of the ball. The SteelFiber Private Reserve produces a medium trajectory, offering a balanced ball flight that provides reliable carry without ballooning. Ideal for players who want a consistent launch without sacrificing control.
Spin: Medium Control
Spin impacts both stopping power and distance. With medium spin characteristics, these shafts deliver the perfect blend of playability and precision—helping golfers hold greens while maintaining penetrating ball flight.
Why Choose SteelFiber Private Reserve
For players who demand Tour-level performance, SteelFiber Private Reserve offers proven technology, ultra-tight tolerances, and a balance of trajectory and spin that elevates iron play to its highest standard.
