Callaway Razr Hawk Driver has an Aldila RIP Graphite Shaft
The Callaway Razr Hawk Driver has streamlined surface contours to reduce energy loss from drag during the downswing by 43% compared to the FT-9 Driver. This creates higher impact speeds for added distance. The sole and crown of the Callaway Razr Hawk Driver contains more than 23 million turbostratic carbon fibers that reinforce 67% of the clubhead. This allowed engineers to precisely control thickness like never before, resulting in a clubhead that's lighter, stronger than titanium but still has an extremely high moment of inertia. The lighter clubhead enables a longer club configuration for faster head speed, ball speed and greater distance without compromising forgiveness.
