More Information about Recoil from UST Mamiya:

Recoil is a revolutionary design concept for Iron shafts that incorporates state of the art composite materials and over 30 years of golf shaft design experience.  UST Mamiya engineers have uncovered the secret to designing an iron shaft using carbon fiber that exceeds the performance of traditional steel shafts and previous carbon fiber shaft designs. See a tech interview with UST by clicking here.

For years engineers have tried to develop carbon fiber shafts that could matchup to steel, but they usually failed because of the weight constraints and lack of engineering ingenuity.  The reason for their failure was due to poor material alternatives and poor design methodologies.

The conventional graphite shaft designs were constrained due to weight.  In order to create a heavy carbon fiber shaft, engineers used heavy weight carbon fiber material which had very poor dynamic properties and would cause the shaft to feel dead and non-reactive to a golfers swing.  The most common design method for adding more weight was to increase the quantity of angle layers. This was the cause of very poor recoil properties and resulted in bad feel or dead feel, and poor playability in iron shots that resulted in poor distance, trajectory and accuracy control.

The wall construction was too thick and the material properties not favorable in producing dynamic recoil within the walls of the shaft.  Recoil iron shafts has a much thinner “angle” layers, the angle layer is the most important part of creating the recoil effect.

Recoil iron shafts has been able to maintain both the heavy weight and very active recoil properties such as hoop stiffness and active modulus properties by adding more “straight” layers and utilizing high-density material and reducing angle layers.

Features and Benefits:

• Recoil technology allows the golfer to load and unload the shaft better on both partial and full shots, which results in better:

• Trajectory control
• Distance control
• The shaft is redirecting the energy to the ball and is also transferring stored energy from the golfer to the ball.  This increases the spring effect (recoil) in the walls of the shaft for efficient energy transferred to the ball for increased velocity and greater distance.
• Composite material construction for enhanced feel and feedback

• Higher damping rate = better feel
• Less stress on joints in the hands, wrists and elbows
• Recoil™ iron shafts have a premium ION plating for a similar look to steel for easier transition from traditional steel shafts to recoil™ graphite iron shafts.
