This is the largest oversized USGA legal Ti driver available in America!! The new very golfer friendly WB-40 TI oversized volume is achieved by taking a 490cc ti body and attaching our patented “inverted sole” design that effectively lowers the legal measured volume to 459cc. Advanced forging techniques combined with a thin 2.1mm C-cup(tm) face allow maximum distance with more low and rearward weight for extra forgiveness and optimal trajectory. The extra large face means more ball rebound and distance from off center hits. Check it out - the new WB-40 will out preform any ti driver from Golfsmith(tm), Callaway(tm), or Taylor Made(tm). Guaranteed.
