Graphite Design has developed a new proprietary composite technology, Axial Composite Interlace or ACI technology.

Composite materials are strategically aligned to offer every Graphite Design shaft ultimate performance for each design. The axial orientation placed in the proper zone of the shaft gives you superior feel and playability. The diagram shows how different materials are used during the manufacturing process. The superior playability comes from an increase in shaft stability creating ideal launch and spin conditions for more distance and better accuracy. ACI technology will give you the best feeling golf shaft ever.

ACI technology is used in all Graphite Design shafts. This technology in combination with a proprietary 4 AXIS weave material  can be found in the Tour AD QUATTRO TECH and QUATTRO TECH MD shafts from Japan along with the YSQ designs.

The 4 AXIS weave offers some shaft design parameters that help the golfer, of all skill levels, get PURE DISTANCE and PERFECT ACCURACY
