What we say...
Spine driver is powered by its innovative crown super-structure and unique perimeter weighting, the new women's Spine driver explores today's new driver geometry, generating high MOI with explosively long and accurate results. The Spine achieves high MOI and low CG by redistributing weight from the center of the crown to the perimeter. The result is the industry's first truly perimeter weighted driver with a higher MOI and lower CG than traditional 460cc drivers.
High MOI Low CG
Weight scooped out of the crown was moved down around the perimeter to lower the CG for higher launch angle and preferred lower driver spin.
Perimeter Weighting For Greater Forgiveness
A unique "spine", or ridge line, reinforces the face behind the impact area, offering even hotter ball speeds.
UST V2 HMOI Shaft
Because of the superior stability produced by the non-traditional head, the standard shaft offering is longer to maximize distance while maintaining control.
