For players with moderate swing speeds seeking an ultra-lightweight configuration to help maximize distance. Features super-lightweight components and a deep, face-centered CG for increased launch and exceptional ball speed. From clubhead to grip, TSi1 metals have been strategically engineered and weighted to deliver maximum launch and distance at moderate swing speeds. Players often equate "high MOI" with heel to toe forgiveness, but Titleist employs a more holistic approach to MOI design. Their inertia also delivers more speed and a tighter spin range up and down the face, freeing you to attack every drive. The adjustability features of TSi have been engineered to deliver maximum benefit for every player. Titleist continues to refine the ways in which a fitter can fine tune performance to ensure you get the most out of every swing. ASCENT Ultralight shafts deliver an easy, high launch angle without the typical compromises of an ultra-lightweight shaft. Featuring Focused Mass Technology, a precise weighting section that utilizes heavier, tungsten-infused prepreg in the butt end to help players turn through the ball better for stronger, straighter/drawn ball flight. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard Titleist warranty applies and satisfaction is guaranteed.
