New Speed Bridge structure unlocks the ability to use TaylorMade's most flexible thru-slot Speed Pocket engineered to generate more ball speed than ever before. Additional stiffness in the head structure provides higher ball speeds due to reduced energy loss at impact. An ultra-thin face design with Inverted Cone Technology (ICT) delivers incredible ball speeds over the entire face areaThe Speed Bridge supports the topline to reduce low-frequency vibrations for a more satisfying sound at impact. Advanced HYBRAR compression damper effectively filters unwanted face vibrations for more solid feel on all shots. Fluted Hosel and 360* undercut effectively lowers CG to increase launch angle and ball speed to generate a strong, penetrating ball flight even on low-face impacts. Multi-material construction uses high density tungsten for maximum forgiveness in a compact game improvement iron design. Patented off-center Inverted Cone Technology promotes straighter shots for golfers at all levels. Please contact us if you would like to customize set makeup, lofts, lies, grips, or shafts.
