The Grafalloy Epic shaft features a proprietary Nanofuse material created by harnessing the superior strength properties of nano-crystalline metals and fusing them at the molecular level with a composite polymer substrate. The result is an entirely new high-performance shaft material that offers increased distance with a 35% improvement in shot dispersion compared to graphite shafts on the market today. The Grafalloy Epic shaft is neither graphite nor steel. It is constructed from a revolutionary new material called Nanofuse. This material is proprietary and exclusive to Epic.
