High- Elasticity Carbon Delivers Unprecedented Initial Ball Speed and Long Carry Covering the thin sole slot with carbon strengthens the T// World 757 S Driver’s face, while saving weight and increasing repulsion at impact. This yields the highest initial ball speed in HONMA’s history. S = Spin and Stability Control The World's First Carbon Slot The thickness of the sole slit is thinned to maximize the repulsion performance, and it is reinforced with carbon to maintain the strength. As a result, it succeeds in maximizing repulsion performance. Adjustable Weights The front and back weights are interchangeable - helping maximize performance, by optimizing the weight positions to a golfer's swing type or required trajectory. Front: 3g and Back: 9g (standard) weights achieve effortless high launch and straight ball flight. Front: 9g and Back: 3g weights achieve high initial ball speed and strong trajectory and enable spin control. New Vertical Slot Clubface This 450cc driver features the most effective vertical slot clubface for mishits from the upper and lower clubface. It maintains high initial ball speed, even on mishits, because it increases the repulsion power on a wider area of the clubface. Carbon Crown Cross carbon is adopted to the carbon composite structure, to enhance the head repulsion performance by crown rebounding. That reduces weight and enables the ideal CG design. Crown Rib The ribs maintain rigidity around the clubface and efficiently use the rebounding carbon energy for high initial ball speed. The two thick and long ribs prevent over-rebound in a wide area. Keel Design Placing the back weight at the outside of the sole achieves low-and-deep CG. P-SAT Precision Spine Control The spine is set identically on all clubs, to stabilize shaft movement and retain consistency through the set. NON-ROTATING SYSTEM The HONMA original system enables to adjust lie, loft, and face angle without rotating or detaching the shaft, by using the included torque wrench. The angle adjustment system provides consistent shaft performance in combination with P-SAT, even if changing the angles.
