TSI2 DRIVER

 

PURE DISTANCE

For players seeking incredible speed and accuracy across the entire surface of the face, the TSi2 driver features a deeper, lower CG to maximize distance through Speed Optimized MOI design.

ATI 425 AEROSPACE TITANIUM FACE

Accurately tuned for speed at every point of contact, TSi driver faces are constructed from ATI 425 Aerospace Titanium, a unique material that delivers superior strength, elasticity and durability versus the conventional titanium alloys used in golf. The exceptional ductility of ATI 425 (30 percent higher than 6-4 Titanium) allowed engineers to produce Titleist’s fastest driver face, while maintaining the durability properties required for consistent maximum performance.

“ATI 425 is an amazing alloy that leads to a lot of performance benefits,” said Dan Stone, Senior Vice President, Titleist Golf Club R&D. “It’s incredibly strong and maintains elongation under high stress. It let us optimize the thickness of the entire face to a degree that was never possible before and generate our highest ball speeds ever at points all over the face – not just heel and toe but also high and low. This is not an easy material to obtain, but the benefits to the golfer are beyond anything we’ve ever seen.”

Made by a single foundry in Pittsburgh, ATI 425 was initially developed for ballistic armor and has since been used in many aerospace and industrial applications, including NASA’s Phoenix Mars Lander. Titleist is the only company in golf that uses this material.

The TSi face also features a new high-contrast graphic design that accentuates face center for easy alignment at address.

PLAYER-TUNED AERODYNAMICS & SOUND

The improved shaping of TSi allows the clubhead to move faster through the air and deliver a more powerful impact. Both TSi2 and TSi3 have been aerodynamically engineered to reduce drag up to 15 percent (versus prior generation TS models), increasing clubhead speed for greater ball speed and distance. The new head shapes feature a tour-requested softer toe profile that looks square at address.

TSi feels fast in a golfer’s hands and is complemented by meticulous sound engineering that manages vibrations within the clubhead to deliver a Tour-quality sound.

MULTI-DIMENSIONAL STABILITY

While golfers often equate “high MOI” with heel to toe forgiveness, Titleist R&D employs a more holistic approach to MOI design. TSi also optimizes sole to crown performance, producing up to 13 percent higher inertia values (versus prior generation TS models) that deliver more speed and a tighter launch and spin range up and down the face.

TSi’s speed-optimized MOI works in concert with a low and deep CG position to drive faster ball speed with a high launch, low spin trajectory and exceptional stability for greater distance consistency.

PERFORMANCE-TUNED ADJUSTABILITY

Both TSi2 and TSi3 feature Titleist’s patented SureFit hosel with 16 independent loft and lie settings, plus headweight adjustability (in two-gram increments, ranging from -4g to 4g) to create a more consistent and optimized ball flight through precision fitting.

CT TESTED AND MAXIMIZED

Every TSi driver is precision manufactured to the tightest tolerances and measured multiple times to ensure performance is at the maximum allowable limit.
