The React Core is a midsize/oversized grip with rounded sides and minimal taper top to bottom and provides a wide flat section for both thumbs to sit comfortably whilst maintaining the patented off-centre shaft design.

The off-centre shaft design increases ulnar deviation and creates a more arched wrist position throughout the stroke by lifting the hands slightly higher at address. This position is biomechanically proven to limit the amount of wrist movement by effectively locking them in place.

The off-centre shaft design and its effect on the wrists places the shaft of the putter in a flush line with both forearms, making it a much simpler task for the putter, hands, wrist and arms to work together as one unit. This connectivity will significantly improve your accuracy and pace putting from distance.

The rounded sides form a V-shape and encourages the elbows to turn inwards and sit tighter and closer to the body which helps to set the shoulders back and allows the bigger muscles of the body to control the stroke.

As the shaft sits on the underside of the grip you still have the sensation of gripping in the fingers as you would for full shots. However, the top edges on each side of the grip sit higher in the palm now running through the lifeline which further reduces the  ability of the wrists to influence the stroke.

The React Core is 80g heavier than the Tour version so has more of a counterbalance effect on the putter.
