TSI1 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.
ATI 425 AEROSPACE TITANIUM FACE
Like the TSi2, TSi3 and TSi4 drivers, the TSi1 also features the ATI 425 Aerospace Titanium Face. Faster in the air and faster at impact, all Titleist TSi drivers push the boundaries of speed through advanced engineering and material breakthroughs. This new face construction has previously never been used in golf and helps produce the longest, straightest, best-looking, and best-sounding Titleist drivers ever.
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. Titleist is the only company in golf that uses this material.
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 SHAPES
The aerodynamic designs reduce 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.
