MOI+ Design An adjustable 10-gram weight at the extreme trialing edge on the sole of the clubhead that creates an extremely high Moment of Inertia. The E725 hybrids extreme low-rearward CG position, which is 10% lower in this design than previous models, produces an extremely high MOI and a deeper CG position. The position of the backweight helps deliver an optimally located CG, maximizing MOI, and aiding extreme stability and resistance to twisting at impact. Adjustable Rear Weight This adjustable rear weighting features a 10-gram weight at the extreme trailing edge on the sole of the clubhead. The position of the backweight helps deliver an optimally located CG based on the individual player and their swing. Installation of different weights also allow the dialing in of required swing weight at custom lengths. All 725 series weights are swappable from club to club. Nine different individual weights will be available from 5 grams to 28 grams for our latest ever fitting matrix. 360o Ridgeback Technology Tour Edge engineers employed the Ridgeback Titanium brace for the E725 features increased structural properties and 360o perimeter weighting. The 360o Ridgeback wraps around the entire perimeter to frame the entire clubhead. This Ridgeback 360-degree brace acts as a brace for the entire clubhead to produce more power across the entire face, including the extreme perimeters. Adding additional Titanium to the entire perimeter with a thicker ridge at center face allows more support on off-center hits to increase face deflection. 3D Diamond Face New 3D Diamond Face is made up of new three-dimensional shapes of variable thickness located behind the face, bringing the face to life with full depth and height of the Diamond shapes being utilized. 3D Diamond Face coverage removes additional weight from the face and dramatically increases ball speed on off-center hits while also greatly aiding forgiveness strikes to the extreme heel and toe of the clubhead. There are 41 total diamond shapes featured on the 3D Face, comprising of three different 3D thicknesses in an interweaving pattern. The mini-trampolines that make-up 3D Diamond Face create faster ball speeds and an expanded sweet spot, while the reduction in face thickness on the heel and toe adds forgiveness on mishits and dramatically increases ball speed on off-center hits. RyzerSole Technology + Power Channel The RyzerSole on the E725 Hybrid includes a sole rail and added weight that extends from leading edge to trailing edge and a new Power Channel has been incorporated into the 725 designs directly behind the face on the sole of the clubhead. RyzerSole produces a super-low CG for high launching shots with optimized spin rates, decreased turf interaction and maximum ball speed off the face, while the Power Channel creates better weight distribution and increased face flexing and delivers amplified ball speed and less spin, as well as added forgiveness on shots struck lower on the face. Finned Internal Ribbing Upgraded acoustic engineering is achieved through Finned Internal Ribbing strategically placed on the inside of the clubhead. Internally, the finned ribbing bounce sound on the inside of the club head to provide top-shelf sound and feel. Learn More
