Moderate swing speed, meet maximum performance. Titleist TSR1 Driver’s incredible lightweight configuration and enhanced aerodynamics make it easier to generate more speed. The new Multi-Plateau Variable Face Thickness design optimizes ball speed across the entire face. Every unnecessary gram, from head to grip, has been eliminated from the design of TSR1. It is strategically engineered to be as light as possible while still providing maximum launch and distance dynamics. This new Variable Face Thickness construction approach builds the face inward, layer by layer, to create a large sweet spot across the entire hitting surface. In other words, it produces amazing forgiveness and ball speed from every strike. The deep center of gravity in TSR1 is almost perfectly centered to the face, an improved position that promotes a higher launch and exceptional ball speed.
