Product description

The AeroTech SteelFiber CW iron shaft blends the stability of steel with the responsiveness of graphite, creating a profile that feels familiar yet offers a different level of efficiency through the swing. It has become a long-standing choice at the highest level of the game, trusted for its consistency, control, and ability to deliver repeatable performance across a full set.


At its core, SteelFiber technology wraps thousands of microscopic steel fibres around a graphite core. This construction stabilises the shaft without adding unnecessary weight, helping to control dispersion while maintaining a smooth, responsive feel. The result is a shaft that loads naturally, releases predictably, and supports a more consistent strike pattern.

SteelFiber Technology

A unique construction that integrates steel fibre strands over a graphite core. This combines the strength and stability of steel with the vibration dampening and weight benefits of graphite, creating a more controlled and efficient shaft profile.

Constant Weight (CW) Design

Each shaft in the set is designed to maintain consistent weight progression, supporting uniform feel and timing from long irons through to wedges. This helps promote a more repeatable swing and consistent distance gapping.

Balanced Performance Profile

The SteelFiber CW range is designed around a mid launch and mid spin profile, with lighter models offering higher launch characteristics and heavier models providing a more penetrating flight. This allows for precise fitting depending on tempo, delivery, and desired ball flight.

Tour-Proven Consistency

With extensive use at the professional level, SteelFiber shafts are recognised for their ability to deliver tight dispersion and reliable performance. They suit players looking for control without the harsher feel often associated with traditional steel shafts.

Performance Characteristics

Designed to suit a moderate tempo, the SteelFiber CW profile offers smooth loading through transition and a stable release through impact. Launch and spin characteristics vary through the weight range, allowing players to fine-tune trajectory and control.
