"Unofficial High-Repulsion Drivers Flood Market: 'How Much Further Can They Go?'"

Big Heads Over 500cc Join In, Optimal Loft and Shaft Selection Through Fitting, Basic Physical Training Essential

It is also important to find the perfect specifications that fit your body through a test swing with an 'unofficial high-rebound' driver.

[Asia Economy Kim Hyunjun, Golf Specialist Reporter] "Ultra-lightweight, non-conforming high COR, and big head drivers."

It is truly the golden age of 'long-drive drivers.' Golf equipment makers have been releasing non-conforming models that exceed the face coefficient of restitution (COR) limit of 0.83 set by golf rules for several years now, stimulating the long-drive instincts of amateur golfers. Recently, ultra-large drivers with head volumes reaching as much as 550cc have appeared, drawing even more spotlight. These are especially popular among women and senior golfers, who generally have less power.

The starting point is 'ultra-lightweight.' First, the club must be light enough to swing freely, allowing acceleration during the downswing to transfer all energy to the ball at impact. For some golfers with slower head speeds, testing with women's specs actually results in longer distances. The shaft is similar. A shaft that is too stiff for the player’s body tends to open the face at contact, reducing the chance of a solid hit.

Bang Golf’s 'Longdistance Light' is interesting with a weight of only 205g. Compared to a typical driver (295g), it is 90g lighter, and even 47g lighter than a lightweight model (252g). This means anyone can swing comfortably. The lighter weight naturally increases swing speed. Added to this is an ultra-high COR technology of 0.962. The brand is expanding its range into woods and hybrid design irons.

Dokkaebi Golf also prioritizes ultra-lightweight as a basic feature. Weighing 243g, it is equipped with the DX-30D shaft, made from multiple layers of 30g-class high-elasticity carbon fabric using a core construction method, providing comfortable control. The Ti-8-1-1 lightweight high-density alloy is manufactured into a 2-piece cup face (2pcs-cup-face) to address the fragility issue. The 500cc head increases the effective hitting area, ensuring forgiveness on off-center shots. Beyond Golf developed a 550cc head, heating up the 'big head competition.'

However, remember that the 'equipment effect' can only be maximized if it matches your body. Different shafts among dozens of models produce varying ball flights and trajectories. Once you choose a brand, it is essential to invest effort in testing to select the optimal loft and shaft. Strengthen your basic fitness with regular stair climbing and sit-ups, and build a solid swing at the driving range with a 'definite shoulder turn.'
