TaylorMade's r7 SuperQuad Driver boasts an Effective MOI (eMOI), which is the positive influence on ball speed on off-center hits that's exerted by the combined effects of a driver's MOI and clubface technology, providing tremendous forgiveness for long, straight results on off-center hits. The TaylorMade SuperFast RE*AX 65 shaft reduces ovaling in the mid-section while allowing a flexible tip.
