It’s all go for January after the R&A and USGA published their finalised Rules of Golf. So what’s coming in? Steve Carroll outlines the changes.
Callaway launches Rogue & Rogue Sub-Zero Drivers
Callaway Golf has launched its Rogue and Rogue Sub-Zero drivers for 2018, and they are designed to deliver greater distance and forgiveness than their BGG Epic counterparts.
The new drivers have vastly improved Jailbreak Technology (debuted in the Callaway GBB Epic) to increase forgiveness. The bars used in Jailbreak Technology are an hourglass-shape in the Rogue and made from titanium, meaning they are 25% lighter without impacting crown and sole deflection at impact. This is key in Jailbreak technology; keeping the crown and sole stiff allows the face to flex more for extra golf ball speeds.
There’s also X-Face VFT, which varies thickness in the face for improved golf ball speeds on off-centre hits, adding yet more forgiveness. Callaway is calling the technologies the “Jailbreak Effect”.
The 460cc head has a larger footprint at address and the light and strong triaxial carbon crown allows for more mass to be moved to the perimeters, aiding off-centre strikes.
Boeing and Callaway continue their relationship in 2018, with an improved Speed Step Technology allowing for an aerodynamic design that means faster club head speeds. The brand says it has again been able to decrease drag thanks to improving how long air sticks to the driver as it moves through the air.
MOI has significantly increased. The Callaway XR had an MOI of 7,400, the Epic had 8,000, while the Rogue is at 8,600, which Callaway says offers a 16% increase in dispersion compared to the Epic.
The Callaway Rogue Sub Zero benefits from much of the same technology as the Rogue in a low-spinning driver. In 2018, Callaway wanted to bring a low spinning driver to market than also boasted high levels of forgiveness. However, the Rogue SZ has a head shape allowing engineers to put CG low and deep with a more neutral bias.
Two interchangeable weights (2g and 14g) in the front and back of the sole allows spin rate to be adjusted up to 200rpm. The SZ Rogue is designed to spin around 3-400rpm lower than the Rogue driver.
