With the RADIX HD, Matrix reinvents what a mid-priced golf shaft should be. Similar to the trickle down of technology in motor racing, the RADIX HD line has benefited from the application of the tour proven HD internal design. RADIX is Latin for “base” or “root.” The “base” for RADIX is the HD Design, giving RADIX HD the most advance internal structure technology in its class. Along with the HD internal platform, this design introduces a new approach to progressive Tip-to-Butt Ratio design.

Unlike conventional designs, which do not increase tip stiffness as butt stiffness is increased, the RADIX HD introduces a unique design that guarantees the same tip-to-butt stiffness ratio throughout the flexes. Since the ratio remains intact, ball flight is progressively flattened as the overall flex stiffens.

The “HD” Design refers to the hexadecagonal (16-sided) internal platform on which the designs are built. HD allows for new levels of structural strength. With the stronger 16-cut butt section, Matrix engineers are able to better structure and strengthen the tip section without adding overall weight, and, at times, even lowering balance points to better match high MOI, low CG heads. The result is a stronger tip-strength-to-weight ratio than with any previous Matrix shafts.

The internal HD structure can be made more consistently uniform than a circular design, further reducing the need for specific orientation during installation.

In terms or performance, shafts with the “HD” label will produce flatter, more piercing Tour-type ball flights and a more stable, crisp feeling.

Keys Points:

* 16-sided internal structure (visible without a grip)
* More consistently uniform than a round golf shaft
* Strengthens the shaft without adding weight

The RADIX 7321 is a unique application of the RADIX technologies designed to meet the demands of modern tour players. Matrix OZIK fans will immediately recognize the RADIX 7321 as a close relative to the Matrix OZIK F7M2 and Matrix OZIK F7M2 STOUT, built on the advanced HD chassis.

In its first week on the PGA Tour, RADIX HD went into play with a PGA Championship winner. RADIX HD is ready to add stability and a new look to your bag. Be true blue.
