How does the weight of your grip affect the swingweight of the club?
The weight of the grip has a direct relationship on the swingweight of the club. The swingweight of the club in very technical terms is the measurement of a golf club's weight about a fulcrum point which is established at a specified distance from the grip end of the club. In less technical terms, it is how the weight of the club feels when you swing it. The grip is important because a club is designed by the manufacturer to have a certain swingweight and a contributing factor of that is the weight of the grip that came stock on that club. If you change the weight of the grip to a lighter or heavier model from the grip that came stock on the club, the overall swingweight of the club will change. Please see the chart below for an explanation of how the swingweight changes with grip weight
Aunque no encuentro la tabla que comentan, ando buscando los pesos de unos y otros a ver qué llevo montado y qué tendría que comprar para igualar el SW.. ¿no es algo que deberíamos mirar cuando cambiamos los grips?
Edito para añadir una url con pesos de algunos grips (notese la diferencia entre ellos):
