Titleist TSi1 Driver

Maximum Launch and Distance

Faster in the air and faster at impact, the new Titleist TSi drivers push the boundaries of speed through advanced engineering and material breakthroughs – including a new ATI 425 Aerospace Titanium face construction never before used in golf – that combine to produce the longest, straightest, best-looking, and best-sounding Titleist drivers ever.

An Ultra-Lightweight 460cc driver, the TSi1 is almost 40g lighter than standard drivers. It is high launching with mid spin and is the most draw biased Titleist driver through CG positioning. By reshaping the head, engineers were able to move the CG closer to face center, which results in more ball speed versus the original TS1.

ATI 425 Aerospace Titanium

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.

Ultra-Lightweight Configuration

From clubhead to grip, TSi1 metals have been strategically engineered and weighted to deliver maximum launch and distance at moderate swing speeds. By bringing TSi technology into this extremely lightweight configuration and adding a slight draw bias, Titleist been able to produce dramatic benefits for this group of players.

Ultra-Thin Titanium Crown

The thinnest cast titanium crown in the game allows weight to be redistributed for optimal driver performance at moderate swing speeds.

Streamlined Shape

The aerodynamic design reduces drag, allowing golfers to swing even faster for increased clubhead speed and more distance.

Optimized Weight Distribution

TSi1’s deep CG locations have been optimized to generate the launch and spin needed by moderate speed players to carry the ball farther, while maximizing off-center ball speed through high MOI properties.

Industry-Leading Adjustability

Titleist’s patented SureFit Hosel, featuring 16 independent loft and lie settings, provides additional ball flight optimization through precision fitting.
