Conclusion: A new era in iron performance! The r7 CGB MAX iron incorporates Inverted Core Technology (ICT), a metalwood breakthrough used to expand the size of the COR zone in TaylorMade drivers. ICT changes the way the clubface behaves at impact and increases the size of the zone that delivers high initial ball speed. This makes the r7 CGB MAX more forgiving and easier to launch and promotes constant distance - exceptional yardage, shot after shot.
Excerpt: Featuring the largest clubface area of any TaylorMade iron. The 2008 r7 CGB Max iron - the longest and easiest to hit model in the TaylorMade line thanks to its thin, fast face and super-sized design. The r7 CGB Max iron features a large, high strength steel clubface that's thin, flexible and fast. This clubface has a high COR (coefficient of restitution) for faster ball speed and extreme distance.
