Titleist has added to its impressive line-up for 2021 with two new drivers in the tour-preferred TSi4 model and the TSi1, designed for players with a moderate swing speed.
The introduction of the new Titleist TSi4 driver provides golfers seeking ultra-low spin performance with the advanced speed and distance gains that have made Titleist TSi2 and TSi3 the most played driver models this season on the PGA Tour.
The TSi1 driver, which is part of the all-new TSi1 family of metalwoods, has been engineered for the moderate (less than 90 mph) swing speed player seeking increased club and ball speed with control off the tee and from the fairway. The moderate swing speed player represents approximately 30 percent of all golfers, making the TSi1 metals an important offering to maximise their performance potential.
TITLEIST TSI4 DRIVER - THE DETAILS
The new TSi4, the driver choice of Adam Scott, Russell Henley and Richy Werenski, among others on the PGA Tour, is engineered to be a high-speed, ultra-low spin design – challenging the notion that a driver designed for extreme spin reduction cannot produce that level of ball speed.
The Centre of Gravity (CG) is the lowest in the TSi family of drivers and it is also the most forward. That allows the driver to deliver less dynamic loft and less spin at impact, providing that low spin promise. A higher Moment of Inertia (MOI) in the TSi4 also contributes to a higher launch, overall trajectory, and produces more distance for that target player. At 430cc, with a very classic, small pear-shaped profile and improved sound and feel, the TSi4 is also the most workable of all TSi drivers.
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 – 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.
ATI 425 Aerospace Titanium is 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.
PLAYER-TUNED AERODYNAMICS & SOUND: The improved shaping of the TSi4 allows the club head to move faster through the air and deliver more power at impact. The TSi4 has been aerodynamically engineered to reduce drag up to 6 percent (versus prior generation TS4 model), increasing club head speed for greater ball speed and distance.
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 optimises sole to crown performance by producing higher inertia values versus the prior generation TS models and delivers more speed and a tighter launch and spin range up and down the face. TSi’s speed-optimised 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: The TSi4 features Titleist’s patented SureFit hosel with 16 independent loft/lie settings, plus headweight adjustability (in two-gram increments, ranging from -4g to 4g) to create a more consistent and optimised ball flight through precision fitting.
ULTRA-THIN TITANIUM CROWN: The thinnest cast titanium crown in the game allows weight to be redistributed low and forward for reduced spin.
STREAMLINED SHAPE: The aerodynamic design of TSi4 – featuring a 430cc classic, pear shape – reduces drag, allowing golfers to swing faster for increased club head speed and more distance.
AVAILABILITY AND PRICE: Titleist TSi4 drivers will be available for pre-sale beginning February 17 and in Titleist authorised retailers on March 15, with an RRP of £519.
TITLEIST TSI1 METALS LINE - THE DETAILS
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 centre, which results in more ball speed versus the original TS1.
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.
The TSi1 fairway metals are a true lightweight setup – almost 50 grams lighter than standard fairway metals. This was accomplished by taking 10 grams of weight out of the head while maintaining the MOI at the same level as the TSi2 fairways. To accomplish that, the CG depth is positioned further back which contributes to higher launch. Like the driver, lightening up the overall weight for fairway metals delivers the club speed, brings more ball speed, and gives that player a lot more playability and consistency.
The TSi1 features an Aldila Ascent 40g lightweight shaft offering, a lightweight Golf Pride grip, and the head is 10g lighter. By taking 40 to 50 grams out of the overall club weight, the TSi1 is a perfect fairway metal option for slow to moderate swing speed golfers.
The larger profile, ‘wood-type’ TSi1 hybrids are engineered to deliver high launch and mid-spin, and feature a 455 Carpenter Steel Forged Face. It also has a deeper CG for high MOI and exceptional stability and speed across the face. The Titleist TSi1 hybrids range in lofts from 20º to 29º. In testing, moderate swing speed players preferred it, especially when they were able to generate more club speed and more distance.
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.
TSi1 TECHNOLOGY & PERFORMANCE
- Ultra-Thin Titanium Crown on TSi1 Driver. 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.
- Optimised Weight Distribution. TSi1’s deep CG locations have been optimised to generate the launch and spin needed by moderate speed players to carry the ball farther, while maximising off-centre 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 optimisation through precision fitting.
AVAILABILITY: The new Titleist TSi1 drivers, fairway metals and hybrids will be available for pre-sale on February 17 and in Titleist authorised retailers on March 15.
