The New CF4 Black uses “Pitch Black PLUS” composite with Double Re-Enforced Vertical & Horizontal Weave. Adding “Silver Trace” in the weave increases composite strength. The CF4 Doublewall barrel is lengthened 11% compared to the CF3 by improving “Pitch Black” with “Silver Trace” for a larger hitting area & bigger sweet spot. The New Hub end cap stores energy to provide more power.
