Product details



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.


Ultra-Lightweight Design


From clubhead to grip, TSi1 metals have been strategically engineered and weighted to deliver maximum launch and distance at moderate swing speeds.


Multi-Dimensional Stability


Players often equate “high MOI” with heel to toe forgiveness, but we employ a more holistic approach to MOI design. Our inertia also delivers more speed and a tighter spin range up and down the face, freeing you to attack every drive.


Performance-Tuned Adjustability


The adjustability features of TSi have been engineered to deliver maximum benefit for every player. We continue to refine the ways in which a fitter can fine tune performance to ensure you get the most out of every swing.


Aldila Ascent Featured Shaft


ASCENT™ Ultralight shafts deliver an easy, high launch angle without the typical compromises of an ultra-lightweight shaft. Featuring Focused Mass Technology (FMT™), 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.
