What is RIBCOR?
When the club head of an iron strikes a ball, only a certain percentage of the energy is imparted back into the ball, as reflected by the measured COR of that head. Any flexing of the head that is not directly located at the impact point on the face is lost energy. By strategically stiffening the structure of the iron head, RIBCOR technology greatly reduces energy loss, especially on mishits.
RIBCOR technology works in conjunction with Face Slots to stiffen the area outside the scoreline area while retaining flexibility and COR in the area inside the Face Slots. When these proprietary TaylorMade technologies are implemented simultaneously, the performance benefits are amplified. The outer structure of the iron remains stiff, while the face remains free to flex during impact— enhancing energy transfer that leads to increased ball speed.
By efficiently focusing impact energy directly back to the ball, off-centre hits see higher ballspeeds, more carry distance and improved dispersion. RIBCOR technology also allows for placement of additional mass in the heel and toe areas of the head, resulting in significantly higher MOI than the corresponding 2017 irons. This combination of benefits provides irons with RIBCOR technology a substantial increase in overall forgiveness.
M4 Irons: Straight Distance with Incredible Forgiveness
M4 irons utilise proven TaylorMade technologies made popular with previous models of the company’s irons, including Face Slots and Speed Pocket™, as well as a new, redesigned off-centre Inverted Cone Technology. Each technology has been individually optimised specifically for M4 to deliver incredible distance and forgiveness. Additional technologies in the M4 include a Fluted Hosel 2.0, an ultra-thin 1mm topline along with our thinnest-ever leading edge.
M3 Irons: Straight Distance for the Discerning Golfer
Similar to the M4 irons, the M3 irons push the legal limit of COR to maximise the legal ballspeed across the clubface. TaylorMade engineers were able to accomplish this by incorporating new technologies, including RIBCOR, which stiffens the iron’s body to impart maximum energy to the ball during impact. Additionally, a multi-material damping badge works in tandem with the RIBCOR technology to efficiently dampen undesirable vibrations during impact, providing a clean, crisp sound and feel.
15 grams of high-density Tungsten have been added to the sole of the M3 irons, which allowed engineers to create the more compact head shape while still maintaining desired mass properties in a high-performing iron – low centre of gravity and high MOI.
With M3, TaylorMade also appeals to the eye of the low-to-mid-handicap golfer with a refined, confidence-inspiring shape. Featuring a thinner topline than last year’s M1 and a straighter leading edge for a cleaner address view, M3 delivers powerful, high-MOI performance that boasts shot-shaping ability not typically found in game-improvement irons. M3 irons are also shaped to enhance effective bounce, which helps maintain turf interaction conditions that are suited for a wide variety of players, including higher handicaps.
