LOCK BOOSTER SYSTEM: Crush the ball. An enhanced grommet design that promotes string contact for efficient energy transfer and ball crushing power. Three ribs inserted in-between the grommet decrease string slippage and reduce energy loss when crushing the ball.
Crush Zone is an innovative grommet system that compresses at impact and increases ball dwell time on the strings. The benefit of this technology is better feel and more potential energy that drives explosive power.
