About this item These are Callaway’s fastest irons ever. They’re built with wide soles, enhanced offset, and a thicker topline vs. Rogue ST Max. The Lite version features more loft, lighter shafts and lighter swingweights to make these our easiest-to-swing Rogue model. They’ve applied new A.I. Face Optimization to Rogue ST MAX OS LITE. It’s unique for each model and loft to create spin rate consistency across the face. It delivers high launch and COR plus a more controlled landing angle to help hold greens. Callaway’s new precision tungsten weighting features up to 46g of high-density tungsten, a 188% increase over MAVRIK. This provides improved launch conditions and maximizes speed across the face. Their patented urethane microspheres are now pushed further up the face in Rogue ST irons (up to the 6th groove) to enhance sound and deliver pure feel while maintaining fast ball speeds.
