PING's ALTA J CB, S flex shaft. It's a genuine shaft for the G400. - Model Name: ALTA J CB - Flex: S flex - Brand: PING Length: 44.75 inches after attaching the driver head (1 inch butt cut from the original length) Weight: 111g (including grip) (Measured by an amateur) The grip is a Tour Velvet Plus4 Standard. The right hand portion is as thick as 4 layers of underwrap, making it difficult to hook left and easier to control. It has little wear and tear and can still be used as is. Thank you for viewing.
