Cadence TR models advance putter fitting by utilizing different-weight face inserts to fit golfers for their stroke tempo and feel preference. Traditional-weight inserts (blue in color) typically fit mid-to-faster tempos and can improve lag putting. Heavy inserts (black) match slower strokes and can lead to better results on shorter putts. Next-generation True-Roll Technology grooves vary in width and depth to provide unmatched ball-speed consistency and accuracy on putts of any length.
