MainFrame XL Face MainFrame XL Face Technology uses a variable thickness pattern that maximizes flex at impact to boost distance. It also repositions weight low and deep in the clubhead for added forgiveness and consistency. XL Head Design With an improved XL Head Design packing even more MOI than last generation, plus a low-and-deep weighting profile, players can enjoy long, high-launching ball flight with plenty of forgiveness. With alternating flex zones acting in-sync, Rebound Frame directs more energy into the ball for speed and distance on every shot. Action Mass CB An 8g weight tucked into the end of the shaft counterbalances the club for more control without extra effort. This counterweight helps the club feel lighter on takeaway and stay stable through impact. Adjustable Hosel With an adjustable hosel, you can fine-tune your launch angle, distance, and shot shape. Adjust your loft, face angle, and lie angle with 12 different positions. The wrench is sold separately.
