Cadence TR models advance putter fitting by utilizing different-weight face inserts to fit you for your 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. True-Roll face technology provides unmatched ball-speed consistency, the key to holing more putts and reducing three-putts.
