A set containing 6 clubs (5-PW). New Callaway MB -21 now with weight in the center of the clubhead for precise swingweight. A tour inspired muscleback blade club, perfect weapon for the really good golfers. Classic look in chrome and thin top line with optimized CG placement for excellent control.
Tour Shaping and Design The world’s best players provided extensive feedback to help make this a true muscleback iron. This is a classic shape and style, with a traditional, slightly thinner topline, and a beautiful bright chrome finish in our smallest blade head shape.
High Performance 20V Grooves Precision grooves are built in to promote the high level of control and consistent spin that muscleback players expect out of any playing conditions. The 20V grooves also stand out for reducing fliers from the rough to deliver even more control.
New CG Weighting We’ve engineered a new weight in the center of the clubhead. This allows us to precisely dial in swingweights without sacrificing CG location.
