Callaway VENTUS shaft, 45.5 inches, Flex SR, Callaway sleeve - Model Name: VENTUS - Brand: Callaway - Length: 45.5 inches - Flex: SR Thank you for viewing. This is the shaft that came with a Callaway Rogue ST. I am selling it because I changed drivers from Callaway. I think it's an easy-to-use shaft with a mid-kick point. * The grip is a MID size.
