Working with something as tough as ATI 425 Aerospace Titanium isn’t easy, which is why no one else does it. But this unique alloy, made by a single foundry in Pittsburgh, is the key to creating a driver face that delivers increased ball speed at every point of contact.
Improved aerodynamics lead to added speed that you can turn loose on the course with confidence. TSi is tuned to feel fast in your hands and look square at address, with a shape as satisfying as the sound.
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.
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.
