Callaway Great Big Bertha Epic Sub Zero Fairway
Callaway Great Big Bertha Epic Sub Zero Fairway Wood
Emerging from a research and development project (that was a reaction to the discoveries made over the past two years, during which it was demonstrated that the face interacts differently and more favourably at impact than it had with previous, highly flexible models) is a range that features a fortified frame immediately behind the face. Instead of letting the flexibility dissipate across the sole and crown, this method forces it to be concentrated at the club’s face. Callaway is once again challenging the accepted norm with innovative design logic that aims to stiffen the new GBB Epic clubs rather than enhance overall flexibility.
Callaway’s director of R&D for woods states, “Our new driver family represents a breakthrough in technology, innovation and performance… First and foremost, 'Jailbreak' technology consists of two 3-gram titanium bars that connect the crown and sole near the face and fundamentally change the way the body and face behave at impact.” These new multi-material drivers have captured the attention of the pros, including Rory McIlroy. The company notes that a thinner and more flexible face, when combined with a rigid body, produces greater ball speed, energy transfer, and longer drives. Gibbs also mentioned that the structure stiffens the body, allowing for greater deflection of the face – greater face loading ultimately creates a larger area that emulates centre-hit performance by delivering superior ball speeds.
