A new Exo-Cage design with super-light triaxial carbon in the Callaway Big Bertha Fusion woods is said to take forgiveness to a whole new level
Twelve years on from the original Fusion woods, Callaway has relaunched the franchise and turned to an aerospace-grade titanium exoskeleton called an Exo-Cage to bring it right up to date.
This has been paired with a crown and sole made from triaxial carbon, a material that is over 65 per cent less dense than titanium and more than 35 per cent thinner than Callaway’s previous composite material.
This allowed Callaway engineers to relocate a whopping 35g inside the Big Bertha Fusion clubhead where it can optimise the centre of gravity (CG) and increase the MOI by 17 per cent compared to the XR16 driver - a remarkable jump that increases forgiveness further than it has gone before.
By precisely positioning the CG, golfers should enjoy the benefits of a high launch, low spin set-up which promotes longer drives. It’s not the triaxal carbon on its own that gives this performance benefit, it is the material difference it makes to the design of the club, and the options it then gives us to move weight to where it is of most benefit to the club’s performance.
The aggressive shaping of the head, being deeper from front to back, is reminiscent of the Callaway FT-iZ driver or the Titliest 907 D1 driver from years gone by. This shaping creates a driver with even higher MOI, or resistance to twisting. So even on off-centre hits, golfers will be able to hit straighter drives, more often.
There’s also the addition of the Speed Step on the crown, designed in partnership with Boeing, drag is reduced and this, in turn, improves air flow resulting in more club head speed and longer drives.
To increase the potential for accuracy even further, the Callaway Big Bertha Fusion driver comes in two shaft length options; 44.5” for enhanced control or 45.5” for greater distance potential.
A forgiving Big Bertha Fusion fairway joins the driver, sharing its extremely high MOI design to boost off-centre performance.
It’s crown is also made from the ultra-light, ultra-strong triaxial carbon material and weighs just 5.8g, which is a massive 78 per cent lighter than a titanium crown. It also boasts a Hyper Speed Face Cup, keeping ball speeds fast from across the face for more distance.
Available September 30th, the driver will come in 9˚, 10.5˚, 13.5˚ lofts with an RRP of £369, while the fairway wood will come in lofts 15˚, 18˚ and 21˚ and will cost £229.
