Epic Sub Zero’s power is based on Callaways innovative new Jailbreak Technology, which fundamentally changes the way the head and club face behave at impact to deliver more ball speed and distance. The key structural components of a metalwood crown, sole and face – each bend, flex and rebound at impact. Because they’re connected, they influence each other’s dynamics. Jailbreak Technology creates a remarkably efficient relationship between these components to promote more ball speed across a much larger area of the face.
Jailbreak positions two ultra-light (3g), strong titanium bars behind the face, parallel to each other and connected on either end to the crown and sole. The size, strength and position of each Jailbreak bar work together to reduce how much the crown and sole deflect, forcing the face to take on more of the load created at impact than ever before. This results in faster ball speeds across the entire face from swing to swing, promoting more distance.
Features & Benefits
Increased Distance from Jailbreak Technology
A breakthrough innovation which dramatically increases distance by stiffening the body to transfer more energy to the ball.
More Forgiveness and Lower Spin from Exo-Cage Construction
Innovative head construction that unites our aerospace-grade titanium Exo-cage with an ultra-light triaxial carbon crown (10.8g) and sole (7.4g). That allows improved perimeter weighting for more forgiveness and makes it possible to position the CG in line with the neutral axis, which lowers spin.
Spin Control and Trajectory Control from Interchangeable Weights
Two interchangeable weights in the head (2g and 12g) to adjust spin-rate and launch angle. Position the 12g in the forward position to lower spin and in the back position to promote higher launch and raise the MOI.
Faster Head Speed from Industry-leading Aerodynamics
The streamlined head incorporates our proprietary Speed Step, created with direct input from aerodynamics experts at Boeing, to improve airflow to encourage more swing speed and distance without extra effort.
An OptiFit Hosel allows for further fine-tuning in the fitting process to aid precise shot-shaping and adjustment of lofts up and down if required.
Four High-Performance Stock Shaft Options
Diamana M+ Green, Project X HZRDUS, Fujikura Pro Green and Aldila Rogue Max in five weight classes: 40g, 50g, 60g, 70g, 80g. Each premium, tour-proven shaft enables fitting to dial in performance for every player correct through weight, torque and flex profile choice
