Titleist adds TSi4 driver and TSi1 driver, fairway wood, and hybrid



Finding the right driver is all about fitting. To better help more golfers find the perfect fit, Titleist is extending the new TSi Series with the TSi4 driver and the TSi1 driver, which will also for the first time be offered with an accompanying TSi1 fairway wood and hybrid.

The additional TSi1 and TSi4 drivers should be no surprise considering the success both the original TS4 and TS1 drivers had with helping golfers outside of the main chunk of the fitting bell curve optimize launch condition and gain distance and control. But what is new is the additional TSi1 fairway wood and hybrid, which allows more golfers to get the same driver optimization further into their golf bags to help with scoring and increase shot trajectory.

Titleist TSi driver technology recap

If you would like to go in-depth on the technology packed in the TSi series, you can check out the original Titleist TSi2 and TSi3 driver launch piece here: 2021 Titleist TSi2 and TSi3 drivers continue the Titleist Speed Project, but let me give you a quick recap.

  • New ATI-425 Titanium face insert: This Titanium alloy allows engineers to make the faces thinner to reduce weight while also increasing the overall elasticity for better ball speed retainment. This leads to higher COR/CT around the entire face while still keeping within compliance of the rules. Compared to the conventional titanium alloys used in golf, offers a six-percent higher yield strength, four-percent higher tensile strength, and most importantly a 30-percent higher ductility.
    The material name comes from Allegheny Technologies Incorporated, a massive specialty materials company headquartered in Pittsburgh, PA.
  • Faster shape: The reshaping of the driver has created on average a 15-percent reduction in total drag around the head thanks to improved aerodynamics.
  • Higher MOI and tighter spin robustness: Using the new material to save weight from the face, allows the TSi Series drivers to have boosted MOI over the previous generation beyond the traditional heel and toe forgiveness. The drivers are also more stable higher and lower on the face to help boost “high-low” MOI to create smaller launch windows and greater spin robustness – which is another way of saying the head creates more consistent numbers and smaller standard deviation from optimal conditions when hit off-center.

Titleist TSi4 driver

The TSi4 driver is for, as Titleist likes to say, “The player seeking ultra-low spin performance with advanced speed.” The TSi4 is the most workable driver in the Titleist line thanks to its smaller shape (430cc) and low and forward center of gravity.

This low and forward CG helps produce on average 250 rpm less spin than the new TSi3, and if you already happen to have a TS4, it will offer a further 130 rpm lower spin on average while also providing a half degree of extra launch.

These are incremental improvements, but it’s important to note that when working with golfers on the highest end of the speed and spin spectrum, every single percentage point matters and that is what the TSi4 driver delivers.

TSi4 driver specs

The TSi4 will be available in the lofts of 8.0°, 9.0°, and 10.0°, with only the 9.0° head available in left-handed.

The featured shafts are the Mitsubishi Chemical Tensei AV White RAW 65 and ProjectX HZRDUS Smoke Yellow 60.

TSi1 driver, fairway wood, and hybrid

The TSi1 driver has been optimized for moderate swing speed players—those who swing at less than 90mph with their driver—to increase club speed, resulting in faster ball speeds, more distance, and greater control, thanks to an overall lightweight design.

When I say lightweight, I mean lightweight! The TSi1, in a standard configuration with its featured shaft, comes in at just over 40 grams lighter than most standard drivers. This lighter package makes it easier to control and also helps the target player gain just under 2 mph on average based on Titleist’s extensive testing.

This leads to an extra 1 mph of ball speed compared to the previous generation TS1 thanks to the new shape and face design and also results in a gain of 300 rpm, which for players in this speed range helps increase carry and distance.

TSi1 driver specs

The TSi1 will be available in the lofts of 9.0°, 10.0°, and 12.0°, with only the 10.0° head available in left-handed.

The featured shaft is the lightweight Aldila Ascent which only weighs 40g in the  S, R, and R2 flexes and 35g in the R3

TSi1 Fairway wood

The Tsi1 fairway woods as you have probably already concluded is designed for the same moderate speed player, and offer the same technology package as the TSi2 and TSi3: Titleist introduces new 2021 TSi2 and TSi3 fairway woods

Fairway woods are key for this golfer because they hit them more often on approaches into greens and this is where the extra height and spin can be a big benefit.

When compared to a traditional fairway wood the TSi1 is a remarkable 50g lighter, but even in this lighter package it still offers a higher MOI than the TSi2 thanks to the shallow shape and repositioned mass. According to Titleist player testing the targetted golfers gaining just under 1 mph of additional clubhead speed, which resulted in an increase of 1 mph ball speed., as well as hight and spin.

TSi1 fairway wood specs

The TSi1 fairway woods will be available in the lofts of 15.0°, 18.0°, 20°, and a completely new 23° 9 wood through custom order.  The lofts available in left-handed include the 15° and 18°.

The featured shaft is the lightweight Aldila Ascent which only weighs 40g in the  S, R, and R2 flexes and 35g in the R3

TSi1 hybrid

If the TSi1 fairway was a surprise then the TSi1 hybrid should be a shock – I know it was for us when we were first introduced to the club. Titleist has never put a large focus of their R&D into hybrids designed for moderate speed players, instead, most of the work has been used to focus on hybrids designed for higher speed golfers – that is until now.

Like the rest of the TSi1 metal woods, the hybrids are about greater MOI and launch, and the new TSi1’s are the highest MOI hybrid Titleist has ever built. They are on average 20g lighter than a standard hybrid and feature a larger profile “wood-style” design to generate more green holding spin.

In Titleist player testing, which is a crucial element of the development process, the target players gained just over .5 mph in clubhead speed and ball speed, according to Titleist, and for golfers looking for maximum performance, these are measurable gains that lead to better results.

TSi1 hybrid specs

The TSi1 hybrids will be available in the lofts of 20°, 23°, 26°, and a 29° 7H. The lofts available in left-handed are 23° and 26°.

The featured shaft is the lightweight Aldila Ascent Hy in 55g S and R, 50g R2, and 40G R3 flex.

TSi4 and TSi1 series, price, and availability

Both drivers are priced at $550 with featured shafts, while the featured Graphite Design shafts are an additional $200, totaling $750.

The Tsi1 fairway woods will be $299, and the TSi1 hybrids will be priced at $279

The new 2021 Titleist TSi4 driver and TSi1 driver, fairway woods, and hybrids will be available for custom fitting beginning February 16 2021, through Titleist authorized dealers, fitting centers, and at Titleist Thursday events being held nationwide. They will be at retail on shelves starting February 26th.

2021 TaylorMade Spider X, EX, S, and SR putters offer improved roll, feel, and forgiveness



Building putters is about creating options and incorporating technology. For TaylorMade’s all-new Spider putters for 2021—including the Spider X Hydro Blast, EX, Spider S, and SR—it’s the little details that make big differences.

“With this new class of Spider putters, we focused on removing two of those variables: aim and alignment … While each putter brings something unique to the table, they are bonded by a foundation of forgiveness, stability, and True Path alignment that makes it easier to aim.” – Bill Price, Product Creation, Putters & Wedge

The idea of a “classic” golf club or putter shape won’t generally have people reminiscing about a TaylorMade Spider, but the design has been around for well over a decade—and although it has gone through some design tweaks over the years, the modern Spider is here to stay

Spider X Hydro Blast

This putter is all about small changes to an already great design with the most notable being the Hydro Blast finishing process. The new Spider X also features

  • The classic Spider X head shape, available in both a face-balanced double-bend and a smaller slant neck with 21 degrees of toe hang.
  • Multimaterial construction to offer maximum stability and increased MOI.
  • White True Path for a high-contrast look that is easy to align

Availability and Price

Preorder for the Spider X Hydro Blast starts today, March 2, with putters arriving at retail starting March 12 with a price of $279.99.

The new Spider X will be available in stock lengths of 33″, 34″, and 35″ be completed with a KBS Chrome C-Taper Stepless shaft and Super Stroke Pistol GTR 1.0 grip.

Spider EX

With the Spider EX, TaylorMade is flexing its putter design capabilities when it comes to face technology to improve roll and feel. The Spider EX features a new co-molded insert made of white TPU urethane and small aluminum beams angled at 45°. This combination of materials gets the ball up and rolling quicker and also creates a soft yet solid feel to improve player feedback.

Speaking of feedback and feel the Spider EX has a newly designed “Fluted feel” shaft with a more flexible portion starting 5″ below the tip to add stability while also maintaining a softer feel through the stroke,  and is slightly larger than the Spider X to increase MOI.

Availability and price

Preorder for the Spider EX starts today, March 2, with putters arriving at retail starting March 12 with a price of $349.99 – See chart for full color availability.

The stock options will include lengths of  33″, 34″, and 35″, the TaylorMade Fluted Feel shaft and to top it off a Super Stroke Pistol GTR 1.0 grip.

Spider S and SR

It’s about options and alignment. The Spider S uses geometry and topline sights to help golfers who prefer to use the width of the ball for accurate sighting.

The Spider S also offers the same Fluted Feel shaft and white TPU Pure roll insert to create a soft feel.

The Spider SR is the “Stability Monster” of the 2021 TaylorMade putter lineup and utilizes multiple weights around the head to raise MOI.

While the Spider S’s alignment system is for players who use the front of the putter, the SR places the True path alignment away from the face and between the wings. This allows golfers to use the clean topline and parallel wings to line up to the intended path while still offering a visual aid to behind the ball.

Availability and Price

The Spider S and SR putters will be available for preorder March 2 and will land at retail beginning April 9, with a price of $279.99. The stock configurations will include lengths of 33″, 34″, and 35 and they will be completed with a TaylorMade Fluted Feel shaft and to topped with a Super Stroke Pistol GTR 1.0 grip.

‘Can’t seem to chip with forged wedges’ – GolfWRXers discuss



In our forums, our members have been trying to help out WRXer ‘RkoDavey’, who is struggling to chip with forged wedges. ‘RkoDavey’ kicks off the thread saying:

“For most of my golfing life, I’ve struggled to chip with my sand wedge but usually have no trouble when I use my gap wedge, and I’m starting to wonder if this is related to my equipment. My gap wedge is part of my P790 iron set, but no sand wedge is available, so I play an Adams Tom Watson forged 56-degree wedge (bounce is 13 degrees).

 I can’t tell you how many times I chunk little greenside chips with my Adams wedge, but if I chip with my gap wedge, the club seems to glide right through the turf, and I have much better results. My problems arise when I have little green to work with and need the ball to stop quick–my gap wedge simply isn’t the right tool for that type of shot.”

And he poses two questions for fellow members to help him out:

“First, is there something about forged wedges that makes them radically different from your typical gap wedge that comes with a set of irons? I had this same issue with the previous irons I owned, and I wonder if it’s my equipment or if it’s all in my head.

Second, what recommendations can you give for a 55 or 56-degree sand wedge that will perform similar to my gap wedge?”

Our members have been sharing their thoughts in our forum.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • IPA4me: “Check the bounce. Also, consider cavity back wedges for the added forgiveness.”
  • mootrail: “You’re comparing your super hot face hollow body set wedge to an ancient stamping with zero modern wedge design parameters. They might be perfectly fine for some, but the first thing to do is to toss them out. There are a few hollow body wedges out there, but it’s your swing and conditions first. You need to get to the shop and test them out.”
  • jomatty: “I’d check the leading edge between the two clubs.”

GtiClay WITB

“I used to do the WITB more often here. It’s been a REALLY long time. Maybe more than 10 years, and I, unfortunately have only 1 year where I played more than 20 rounds in a year since then. I’m gonna play more… a lot more in the coming years as I’m turning 48 this year and want to have a damn good birthday week at Bandon when I turn 50.

My goal is sub 5 handicap by then. I have still been mostly playing i3 blades and TM 300s. But I want to convert to ‘legal grooves’, so I just picked up my first new set of irons in maybe 15 years. The i210’s… so here’s my current WITB.”

Driver: TaylorMade M4 (10.5 degrees turned a bit to “lower” as I like a slightly open face at address)
Shaft: Ozik Matrix 80M Black Tie X @ 44.5″

3-wood: TaylorMade R9 paintbreak TI (15 degrees)
Shaft: Tipped Ozik Matrix 80M Black Tie X

5-wood: Tour Edge Exotics “ladies edition” (18 degrees)
Shaft: Tipped OG Aerotech SS85 X

Irons: Ping i210 (3-9i)
Shafts: KBS Tour 130X

Wedges: Ping Glide 3.0 46 @ 47*, 54 @ 53*
Shafts: KBS Tour 130X

Callaway PM grind 60*, shaft TBD

(note – this is cold weather setup.  I plan to drop the 3 wood and add my 2019 PM grind 58* and 64* with S400 when it warms up and I need it.)

Putter: Scotty Cameron JAT, TaylorMade Ghost Marenello 355g, both at 34″.

The JAT is somewhere else and due to Covid I haven’t been able to get it, but as soon as I can, I’ll put it into play.

Grip: Stock Pistol

Golf Ball: I love the Callaway HX balls in the wind, but will play most any premium urethane ball that is on sale.

Grips: Golf Pride Tour Velvet Cord BCT midsize with 2x extra tape.

Get submitting your WITB in our forum as we’ll be publishing more and more of them on our front page over the coming days and weeks.
