Inverted Cone Technology
The Inverted Cone Technology inside the R11 Irons promotes faster ball speed and distance on off-center hits.
Precision Weighting Port
A weight port permanently positioned in the center of the back of an iron head during assembly, the Precision Weighting Port assures that each R11 irons in the set is of uniform swingweight while also ensuring that the CG location is precisely and optimally positioned in the center of the face between the toe and heel.
In the past, clubmakers have installed cartridges of varying weight in the hosel to adjust swingweight, and by doing so have pulled the CG closer to the heel to varying degrees, resulting in a set of irons consistent in swingweight but inconsistent in CG location.
Ultra-thin face thickness promotes faster ball speed and distance in the R11 long- and middle-irons.
Tour Inspired Sole Design
The R11 irons Multi-Functional Sole is beveled at the back to make it perform like a much thinner sole, which increases playability from a variety of lies. Yet it also features a low and deeper center of gravity that makes it easy to launch the ball on a powerful and penetrating flight.
