The POWER X by Momentus Golf is the simplest and fastest way to add yards to any of your clubs. Plug the POWER X into the back of any grip and experience more yards and improved accuracy. Before the POWER X, counter-balance weighting for your golf clubs could only be done by professional club fitters. Momentus Golf’s POWER X gives the same results as the more expensive (and permanent) results. The POWER X simply plugs into the back off any club quickly and easily, no drilling, no adhesive, and no damaging your grips or shafts. The best part about the POWER X is the ability to attach and detach without permanently altering your clubs and the POWER X is also interchangeable between clubs. The POWER X conforms to the USGA rules of golf!
