The newest addition to the XR family, The Callaway Steelhead XR Irons, combine the beautiful shaping and playability that made the Steelhead X-14 one of the most popular irons of all time. Paying special attention to some of the design aspects on the original Steelhead Iron, Callaway included a slightly longer blade length, and a slightly more rounded toe and the signature hosel-to-face transition. The speed and distance of Steelhead XR Irons is based on next-generation 360 Face Cup technology, which allows the edges of the ultra-thin face to freely flex and release at impact with greater efficiency, adding ball speed that promotes more distance, especially on off-center hits. The boost in face-speed is so significant that it’s hiked the COR up to almost .830 -- the USGA limit. More speed and distance on mis-hits is made possible by the modern Hollow Bore-Thru hosel design, which allowed Callaway engineers to remove useless weight from the hosel and reposition it in strategic areas within the head to: 1) Increase MOI for more forgiveness on mis-hits. 2) Precisely position the CG strategically in the long, middle and short irons. Steelhead XR long-irons feature an exceptionally low and far-back CG to make them easier to launch high and long. Middle-irons have an exceptionally low and mid-back CG to promote easy launch and keen control. Short-irons have a low and mid CG to make them easier to promote lower, high-spinning shots ideal for attacking the pin. Great feel and sound come from the new steel-infused polyurethane layer positioned low in the head, behind the lower portion of the face. In addition to absorbing unwanted impact vibration to promote a remarkably satisfying sound and feel at impact, it also helps lower the CG to promote faster ball speed and higher launch characteristics for more distance. Put it all together and you have an iron that delivers the finest combination of speed, forgiveness, distance and control to ever emerge from the Callaway R&D department. For a brand with Callaway’s history of innovation and performance, that’s saying a lot.
