This is the genuine shaft (5W) for the Titleist TSi series. The TSP322 provides a satisfying weight, controls head movement for optimal spin, and achieves high launch angles for distance. There are two types of genuine shafts, and this is the heavier one. Recommended for those who want to differentiate the weight from their driver's genuine shaft. The grip is still usable, but it's been a while since purchase, so replacement is recommended. Titleist TSP322 shaft, Flex S, offering precise performance. - Model Name: TSP322 - Flex: S - Brand Name: Titleist Thank you for viewing.
