ONOFF’s largest ever Moment of Inertia equal straighter
more stable shots for powerful consistent distance
MOMENT OF INERTIA AT THE LIMIT OF THE RULES
The AKA RD5900 features a 5 piece design including toe and heel areas made up of lightweight carbon fiber and a heavy stainless back plate. This structure helps create a deep and low center of gravity and the maximum Moment of Inertia as allowed by the rules of golf. Twisting of the head at impact is minimized meaning even off center hits will go far and straight.
POWER TRENCH
More distance and forgiveness
The POWER TRENCH of the AKA RD5900 driver is matched with our original face structure to produce maximum ball speeds and forgiveness.
POWER TRENCH flexes for more distance
Even off-center hits are still powerful
The Power Trenches in the crown and sole help create more consistent flex and more efficient energy transfer when the head recovers its shape resulting in a bigger sweet spot minimizing distance loss on miss hits. Our original face stucture works with trench to create our fastest ball speeds and spring effect right at the limit of golf.
Our Hyper Effect face features a varying thickness V shape design which helps increase spring effect to the limit for more distance.

SHAFT
An exclusive shaft designed and produced in house and featuring DAIWA CARBON TECHNOLOGY made to match the AKA RD5900 Driver for optimal performance and maximum distance.
We’ve designed and produced a special shaft in house with DAIWA CARBON TECHNOLOGY to match the high moment of inertia of the AKA RD5900 head. The HIGH REPULSION KICK RD5900 has enhanced tip stiffness which pairs perfectly with the RD5900 head that minimizes twisting. This combination produces excellent straightness and a powerful trajectory even on off center hits.
