The lightest SteelFiber shaft in our lineup is a great shaft for those slower swing speed players looking to gain as much yardage as possible. This shaft is offered in a wide range of flexes and can hold up to even the most demanding swings. You won’t find a more stable 75 gram iron shaft anywhere. If a player is looking for all of the swing speed they can get or they’re looking to play the golf club substantially over length and want to maintain a reasonable swing weight the i70 is the right choice.
