The 2011 Callaway Diablo Octane Tour club head weighs just 195 grams thanks to a lightweight carbon-fiber crown. Despite the lighter weight, the head still has a low center of gravity (CG) and the off-center hit stability of heavier heads. A 46-inch lightweight shaft is designed to increase swing speed, and a chemically milled cup face helps improve ball speed.
The 2011 Callaway Diablo Octane Tour Driver is fueled by Forged Composite, which is the lightest, strongest material ever used in golf clubs. The new Diablo Octane Driver features that Forged Composite in the crown, giving it a significant performance advantage over all-titanium drivers. These drivers are configured to deliver unmatched power through superior design, construction and materials. The crown contains 10 million turbostratic carbon fibers that make up 33% of the clubhead, allowing Callaway to precisely control thickness like never before. The result is a clubhead that is lighter but still has an extremely high moment of inertia. This lighter clubhead enables a longer club configuration for faster head speed and ball speed for up to eight additional yards over the Diablo Edge. The chemical milling process selectively removes excess material for precision thickness control across the face and consistently high ball speeds for long distance.
