The SuperStroke CounterCore™ Legacy putter grips are our original patented design with the addition of CounterCore™ Technology. CounterCore™ allows golfers to fine-tune the feel of their putter. They also feature No Taper Technology as well as CROSS-TRACTION surface texture to help you with a smooth, consistent, and reliable putting stroke. Putter grip includes 50g CounterCore™ weight and wrench. For those who prefer not to utilize the 50g weight, an aluminum cap is also included. Different weights of 25g and 75g are also available and sold separately.
