New Product Launch: Callaway XR OS Iron
Last year, Callaway launched the XR series of irons with the promise of game-changing distance with new club face technologies that had never been previously incorporated in an iron head. It wasn’t long before the irons ascended to the top of the class and became the number one iron in golf. With a new year, brings the latest chapter of Callaway XR irons with the promise of not only more distance but more forgiveness and easier launch. So how did they do it?
Face Cup Technology
Callaway’s lead research and development team took what they learned from feedback and results of the XR iron through the course of a year to develop the Callaway XR OS Iron. What they wanted to figure out was where the majority of the speed came from in the 360 Face Cup technology. By pinpointing the location, engineers were able to apply a new heat treatment process that enabled the face cup to expand on the zone where high ball speed can be delivered across the length of the blade.
The result is an iron head with the highest COR (a measure of the energy loss or retention when the face and ball collide) of any Callaway iron created. A higher COR means more energy is transferred from the club head to the ball. What this means to you is more forgiveness and even more carry distance regardless of age or handicap level.
Additionally, the XR OS iron features a redesigned sole width and shape with an emphasis on more weight in the lower rear side of the club head. The beveled back edge of the sole and incremental variations of blade length through the set help lower the club’s center of gravity for easy launch and improve turf interaction from each iron head.
Lengths & Lofts
Finally, the loft and length progressions have been adjusted slightly so as to improve the consistently of launch and carry distance. For example, the XR OS 6 iron is 28 degrees and measures 37.875” in length compared to 26 degrees and 37.625” of the XR. Despite the OS Iron utilizing many characteristics of a “super game improvement” club, Callaway was able to keep the body size and top line from appearing too broad or clunky while looking down, which will make it extremely approachable and playable for a wide range of golfers.
The Callaway XR OS irons will feature the same TT Speed Step 80 steel shafts, available in regular or stiff, that were used in XR. The graphite shaft will be the Mitsubishi Fubuki AT 50/55/60, which will be available in senior (61 grams), regular (63 grams), and stiff (68 grams).
