The Hot Launch E524 Iron set is available as a combo set that allows golfers to replace the long irons with E524 Hybrids. This combo set is an extremely versatile iron set available for golfer’s seeking Extreme Game Improvement spec clubs. The E524 2X5 combo set comes with #4 and #5 Hot Launch E524 Hybrids as the long irons in the set. The E524 hollow-body irons known as iron-woods are featured as the 6-iron through Pitching Wedge. This versatile combo hybrid/iron set for the moderate swing speed player, looking for a forgiving hollow-body iron that will maximize forgiveness and launch, while also providing two matching hybrids designed to achieve maximum distance with longer iron shots. E524 Hybrids The Extreme Game Improvement E524 Hybrid includes the patented Houdini Sole along with a super-shallow face, slice-fighting offset designs and heel weighting for added draw bias. Houdini Sole Technology - The Houdini Sole includes an area of mass concentrated on the trailing edge of the sole of the clubhead, as well as a curved leading edge under the face. This unique and patented design creates more area to put extra mass, allowing Tour Edge engineers to precisely position weight in the head for an ultra-low lower Center of Gravity (7% lower than E523), optimizing launch conditions and improving stability. Ridgeback Technology - TE engineers have brought the Ridgeback Tech concept from Exotics to Hot Launch with the addition of a Ridgeback rail on the crown of the clubhead. The Ridgeback rail provides increased structural properties that help produce more power across the entire face, including the extreme perimeters. The Ridgeback activation is also utilized as a unique alignment aid at address. Diamond Face VFT - Diamond Face VFT technology is a breakthrough in face technology that features 39 different thick and thin diamond shapes or “mini-trampolines” behind the face. Diamond Face VFT produces a hotter face with faster ball speeds and better performance on off-center hits, as well as reduced spin. Heel Weighted Slice-Fighting Offset Design - Offset designs are combined with a heel sole weight to provide the ultimate in slice fighting technology. The offset design of the E524 Hybrid added with a heel sole weight allows the face to square up at impact for straighter ball flight. The strategically placed heel draw-bias weighting of the E Series offset designs are engineered to help golfers avoid the right side of the course and to increase launch. Larger Footprint Hybrid Design with a Super Shallow Face Design - The super-shallow face with an 11% percent larger hitting area in the Hot Launch E hybrids is designed for extreme playability and high-flying launch characteristics. The extremely shallow face with the larger hitting area produces higher launch angles and extreme ease of launch with extreme forgiveness. E524 Iron-Woods These hollow iron-wood designs put a major emphasis on ease of launch, playability and correcting miss-hits and slices to go straighter for the ultimate ease of use. The improved hollow-body design of the Hot Launch E524 Iron features the game-changing Houdini Sole in conjunction with a super-shallow face, slice-fighting offset designs and heel weighting for added draw bias. Houdini Sole Technology – The Houdini Sole is a raised steel mass area at the rear of the clubhead, as well as a curved leading edge under the face. The patented Houdini Sole reduces the amount of sole area to reduce drag and turf interaction by 35% and is instrumental in significantly altering the CG placement of the E524 Iron, making it one the highest launching and easiest to hit irons ever produced. Hollow-Body Perimeter Weighting - Hollow-body perimeter weighting produces distance properties of a metalwood in an ironlike design. Hollow-body perimeter weighting produces maximum ball speed off an iron. The hollow body design makes for an extremely low and back CG, helping to create a very forgiving and powerful face. Shallow Face / Offset Design - The super-shallow face coupled with an offset design are designed for extreme playability and high-flying launch characteristics. The offset design acts as built-in slice fighting technology, squaring the clubhead at impact to produce anti-slice ball flights. The extremely shallow face produces higher launch angles and extreme ease of launch with extreme forgiveness. New 524 Shaping - New shaping on the 524 Iron includes a wider front to back length, a thinner top line and more weight located lower in the clubhead. What does it do? The lower Center of Gravity in the 524 design leads to a higher MOI that brings more forgiveness and stability to the clubhead, and also increases launch characteristics to make it easier to get the ball in the air. Ultra-Light Premium Shafts - The E524 Iron comes stock with an ultra-light ALDILA ASCENT PL (Performance Light) graphite shaft. It is also available in a True Temper Elevate MPH 95 steel shaft as a stock option. The ALDILA ASCENT PL provides lightweight performance with faster club head speeds without sacrificing feel. ASCENT PL technology is designed to resist ovaling, keeping the club head in position and creating more center-face contact. ALDILA ASCENT PL is best for golfers seeking lightweight performance and additional speed without sacrificing stability. The True Temper Elevate MPH 95 steel shaft is designed to combat the low spin industry trend. Elevate MPH (Maximum Peak Height) is the lightest and highest launching Elevate shaft ever made, allowing for maximum speed and carry distance.
