ONOFF’s largest ever Moment of Inertia RD5900-C equals
straighter more stable shots for powerful consistent distance
MOMENT OF INERTIA
AT THE LIMIT OF THE RULES
The LABOSPEC RD5900-C head 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.
More distance and forgiveness
The POWER TRENCH of the RD5900-C 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.
ADJUST THE TRAJECTORY
ONOFF Trajectory Control System (OTCS)
Adjust the loft and the lie angle to achieve maximum distance with optimal trajectory.
Adjust the weight screw to change swing feel and swing control
Changing the sole weight screw will:
1. Fine tune the swing weight to adjust feel and improve distance.
2. Adjust the Moment of Inertia to reduce twisting of the head. Increased distance as even miss hits go straight. (Wrench and additional screws sold separately)
