GBB Epic Driver features an innovative new technology called Jailbreak that helps golfers hit longer shots. The key structural components of a driver—crown, sole and face—deform at impact. Because they're connected, they influence each other's dynamics. Jailbreak incorporates two titanium bars positioned vertically behind the face, connected to the crown and sole. The bars’ size, strength and position create a new relationship among the crown, sole and face—creating a profound change in how the head, as a whole, behaves at impact. This results in more impact-load on the face to promote more ball speed for longer distance.
