The Mainframe technology and Rebound Frame take your long game to new heights, and the club not only excels from the fairway but is also perfect for long shots from the rough and fairway bunkers. With two flex zones in the face and head, the Rebound Frame increases ball speed and distance in your shots. The Mainframe technology gives a higher COR area over the face for consistently powerful and precise shots outside the sweet spot. The Action Mass CB, with an 8 gram weight at the end of the shaft, provides increased stability and control without strain. The Gliderail technology with three rails on the sole improves gliding through the grass and stabilises the club at impact, resulting in a significantly improved contact from the fairway.
