The 2009 S9-1 Drivers feature Cobra's exclusive "Hotter 9 Points" technology, which promotes higher ball speed and more consistent ball flight across the entire clubface. To complement the larger, hotter clubface, Cobra has optimized the CG to reduce spin variance, thereby increasing launch and overall distance. And the S9-1 Drivers' refined internal crown rib geometry produce drives that sound and feel as satisfying as they look. Stock Shaft is Aldila DVS HL.

Featues:

• Large face area
• Dual Rhombus Technology
• Revised 460 CC efficient head and face shape
