EQUIPMENT: Titleist Debuts TSi2 and TSi3 Drivers with ATI 425 Aerospace Titanium

It appears that Tour Validation Process—which started a few weeks ago at the PGA TOUR’s Safeway Open and European Tour’s Portugal Masters—has gone very well over the past few weeks, as Titleist is officially debuting it’s next generation TSi drivers with fittings starting November 12th.

“TSi is simply better when it comes to all four fundamentals of driver design – distance, accuracy, looks and sound,” said Josh Talge, Vice President, Titleist Golf Club Marketing. “We continue to make every investment necessary to help players achieve the speed and distance gains they are asking for, without having to make any sacrifices when it comes to performance. ATI 425 is an incredible breakthrough for driver performance, but it’s just one piece of the puzzle. Every aspect of TSi has been optimized to benefit the total package, and it’s the integration of all those parts that drives greater ball speed and an experience at impact that tour players can’t stop talking about.”

As mentioned above, the hallmark feature with the Titleist TSi2 and TSi3 drivers is the face, which is constructed with new ATI 425 Aerospace Titanium, a unique material that delivers superior strength, elasticity and durability versus the conventional titanium alloys used in golf.

“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 applications and has since been used in many aerospace and commercial aircraft solutions, including jet engines and NASA’s Phoenix Mars Lander. Notably, Titleist is the only company in golf that uses this material.

And to help maximize the performance benefits provided by the new ATI 425 Aerospace Titanium face, Titleist has also redesigned the aerodynamics of the TSi2 and TSi3 to have up to 15% less drag (versus prior generation TS models), resulting in increased club head speed for greater ball speed and distance.

Additionally, the TSi newfound speed is complemented by meticulous sound engineering that manages vibrations within the club head to deliver a Tour-quality sound.

That said, speed and aerodynamics weren’t the only things improved on from the prior gen TSi. Indeed, Titleist R&D employed a more holistic approach to MOI design and optimized sole to crown performance, producing up to 13% higher inertia values (versus prior generation TS models) that deliver more speed and a tighter launch and spin range up and down the face.

With respect to the differences between the new TSi2 and TSi3, TSi2 is designed to deliver incredible speed and accuracy across the entire surface of the face, with a deeper, lower CG to maximize distance. Alternatively, the TSi3 is for players capable of creating more consistent contact or requiring more precise control over CG placement, featuring a new SureFit CG Track Design for advanced speed-tuned performance.

Expanding on the new SureFit CG Track Design, the TSi3 can be adjusted in five unique positions to adjust club head CG and fine-tune ball flight. The SureFit CG Track offers more precise incremental adjustments—ranging between H2 (most heel biased), H1, Neutral, T1 and, finally, T2 (most toe biased)—that allow a player to dial-in their launch conditions.

That said, both the 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 allow for adjustability that will facilitate a more consistent and optimized ball flight through precision fitting.

For anyone questioning the sum of the new parts incorporated into the TSi2 and TSi3, Justin Thomas hinted at how potent the new lineup is:

“TSi just looks fast and it sounds like a missile coming off the face,” said Justin Thomas. “When I first tested it I hit one drive off the toe and it carried almost 20 yards further than I would have thought. That’s what we want is the bad ones to perform better. Those weeks where I’m not hitting it consistently in the middle of the face, I feel like this [TSi driver] is going to have the opportunity for me to narrow my window and dispersion… The fact that it is faster without giving anything up – I can’t believe how much it’s improved when it already seemed to be the best that it can get.”

Starting November 12th, the TSi2 will be available in 9.0°, 10.0° and 11.0° while the TSi3 will be available in 8.0°, 9.0° and 10.0°. Titleist shaft options will feature four new aftermarket models—the Mitsubishi KURO KAGE Black Dual-Core 5G (High launch and spin), Mitsubishi TENSEI AV RAW Blue (Mid launch and spin), HZRDUS Smoke Black RDX (Low-mid launch and spin) and Mitsubishi TENSEI AV RAW White (Low launch and spin)—along with the 3 upgrade shaft options available from Graphite Design—the Graphite Design Tour AD DI, Graphite Design Tour AD IZ and Graphite Design Tour AD XC (Xtra Carry).

And if you can’t wait until November 12th, Titleist Fitting Day or Trial events (including Titleist Thursdays) will have the TSi2 and TSi3 drivers available for testing starting today!
