ATI 425 Aerospace Titanium
The driver has advanced aerodynamics to provide increased speed, with ATI 425 Aerospace Titanium in the face which is accurately tuned for speed at every point of contact.
Multi-Dimensional Stability
Attack every drive with better control. The TSi1`s inertia delivers speed and tighter spin across the full-length of the face to give you more confidence to hit every drive.
Ultra-Lightweight Distance
The driver has been developed with super-lightweight components and has a deep face centre of gravity position which launches the ball higher. It provides increased ball speed performance too, for long towering distance performance straight off the tee.
SureFit Hosel
The driver comes with a Ascent 40 shaft option that features 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 and SureFit adjustability. This hosel allows you to fine-tune performance according to personal preference or conditions to benefit you as a player.
Titleist Speed Project
"It began with a challenge from the game’s greatest players. A mission to solicit speed from every detail of the driver, embarked on by a collection of uniquely-gifted R&D minds. The “TS” project is a peerless pursuit of speed where every micron and milligram matter. Two letters that mark the way to the future of Titleist speed."
