Introducing the Epic Sub Zero driver from Callaway. This powerful, low-spinning Tour-level driver is the most forgiving pro-style driver that Callaway have ever made.
Jailbreak Technology places 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 location 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.
With 2 interchangeable weights (12g and 2g) located in the sole at the front and back, you have the ability to adjust the spin-rate ±250 rpm (according to Callaway robot testing), the launch angle and MOI. Installing the heavier weight forward lowers spin; installing it rearward increases forgiveness and promotes higher launch and longer carry.
This excellent driver also features:
Increased Distance from Jailbreak Technology
More Forgiveness and Lower Spin from Exo-Cage Construction
Faster Head Speed from Industry-leading Aerodynamics
1 year guarantee & 460cc head size
Thanks to the Exo-Cage design, this driver is ultra-light. The titanium Exo-Cage with crown and sole panels created from of triaxial carbon, help produce an extraordinarily light and strong composite material. The crown weighs only 10.8g, while the sole panels are just 7.4g. This weigh saving has allowed this club to position the CG low and deep, which promotes a high launch angle and low spin rate.
Head speed gets an additional boost from the latest version of Callaway’s Speed Step technology, which was originally developed in partnership with Boeing. Located on the crown, the Speed Step improves airflow to encourage more swing speed and distance without extra effort. You will also gain extra club head speed thanks to the Speed Step Technology. Positioned on the crown, the Speed Step improves airflow to encourage more swing speed and distance without extra effort. Lastly, you get all the adjustability of OptiFit. This hosel allows for further fine-tuning in the fitting process to aid precise shot-shaping and adjustment of lofts up and down if required.
