Thank you for viewing. This is a 65g shaft from the TENSEI White AV Series, with an S flex and Xlink Tech technology. It's a model for hard hitters, featuring a stiff tip for a low-launch profile, and aluminum vapor-coated weave in the butt section to achieve a low ball trajectory. This is a US model, not sold in Japan, and was used by B. Koepka. - Model: TENSEI White AV SERIES - Flex: S - Shaft Length: Approximately 113cm - Torque: 3.5 - With Titleist sleeve
