One of Callaway’s most successful advancements in recent years has been its “Jailbreak” technology that connects the crown and sole with vertical bars to stiffen the frame so that the face flexes more. Although the design has been tweaked since its introduction four years ago, this year’s Jailbreak has undergone an overhaul with help from Callaway’s artificial-intelligence design platform. For starters, the bars are more like beams now and have been positioned farther apart to work better with the wraparound cupface. The bars also vary in size and width for each loft and head. The result is increased ball speed over a larger area of the face (with an emphasis on shots below the center). The forged, high-strength steel cupface also received the full A.I. treatment to help it deflect at impact like it does on Callaway’s drivers. Furthermore, a carbon-fiber crown helps lower the center of gravity so that shots launch higher with less spin. Making the approach even more effective are the two distinct models. The compact Speed is built for lower spin. The larger Max has more forgiveness than last year’s Mavrik Max and features adjustable weights in the front and back for tweaking trajectory and spin.
