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. A driver that fits better performs better. The SureFit system gives a fitter the flexibility to perfectly match the performance of TSR1 to the needs of each individual player, helping you make purer and more consistent contact. Playing at under 45g in all flexes, MMT SPEEDMESH offers amazing ultra-lightweight speed, with a focused SPEEDMESH application in the tip for incredible stability and energy transfer at impact. A perfect pairing of minimal weight and high launch to pair with TSR1. TSR1 Driver's ultra-lightweight configuration and aerodynamics provide maximum distance and exceptional ball speed from every strike.
