Titleist T100-S irons: Calibrated for distance



The best way to describe the new T100-S irons from Titleist is: More speed, stronger flight, same package.

In the late summer of 2019, Titleist released the completely re-engineered T-Series irons that included the T100, T200, and T300. The T200 and T300 both offer new Max Impact face technology to increase ball speed and launch, while the T100’s greatest performance feature is extremely high MOI in shrunken down player-preferred look—it quickly made the T100’s the number one iron model on the PGA Tour.

Every bit of technology is the same, from the thinner, more responsive face, co-forged dual-density tungsten, to the shape and sole design. The goal was not to reinvent the wheel—just refine it. Similar to the way a Porsche offers a turbo S, but in the case of T100, everything is exactly the same under the hood.

This popularity caused the Titleist iron design team to take a second look at fitting requests, and consult with their large network of TPI fitters to find out if they could do even more to help in fitting players’ wants and needs.

One of the biggest requests was to make the lofts slightly stronger on the T100’s to put them closer inline with the specs of the T200 & T300 for a number of reasons:

  • For players that have grown up with strong lofted irons and lower spinning multi-layer balls, they wanted to see a stronger flight. The issue with just bending them strong is reducing the bounce and increasing offset.

With the popularity and performance of the entire T-Series, it lead to a spike in combo sets being built along with some needed loft tweaking to dial in ball speed numbers between the three models. Rather than increasing loft on the longer irons and producing higher spin, the new T100-S allows the shorter irons to maintain stronger lofts without excess bending.

“As we were launching the new T-Series, we met a lot of golfers who were really excited about T100 but had become accustomed to playing stronger-lofted iron sets. It would have been really easy to just take T100’s and bend them stronger for those players. But by doing that you start to sacrifice the incredible feel and turf interaction … So our engineers went back and redesigned each individual iron to give these players the stronger lofts and distance they’re looking for, while preserving the performance of that pure forged shape and sole.” – Josh Talge, Vice President, Titleist Golf Club Marketing.

New T100-S Specs Vs Standard T100

Stock Shafts and Availability, and Price

T100-S stock shaft is the True Temper Projext X LZ, but just like all Titleist products they offer an expansive number of custom shaft choices, many at no up-charge. The price is $1,399 for an eight-piece set which works out to $175 per club.

They will be available in golf shops worldwide beginning March 27, with fittings beginning March 12.

    How about this, let’s shaft the original t100 one club different, So we can put the 9 iron head in a PW shaft. We’ll just call it a PW and That will net 4 degrees stronger.

    Bam…..we’ve got the new t100SS model

    Can’t wait to bend these 2 degrees strong.

    I hate when companies offer more options.
    I hate when new products come out on a regular basis.
    I hate marketing and believe it to be all lies and money-grabbing.
    I do not believe in technology or improvements over time, unless they are “completely new”.

    I am a rabid defender of capitalism and believe corporations should be free to do whatever they want.
    Words like “socialism” and “regulation” make me so scared they give me bowel disorders.

    I am not in the least bit a hypocrite.

    So is the bounce still decreased? The article touched on this but it never said bounce and turf interaction are the same as the regular T100.

      Dude, no. They made new molds (how they justified this expense is beyond me) for all the irons to keep the standard bounce at the jacked lofts.

      I did notice this when I was looking at the specs to dream up a combo set with T100s in the short irons and noticed the T200 has jacked lofts.

    They didn’t sell enough of the 100 so they went stronger. Laughable.

      I know, right? OEMs just jack up the lofts and claim that the new clubs are “the longest ever.” Of course they are- you just turned a wedge into what was an 8 iron in 1995. Where does it end? When you have to be single digit to get a 5 iron off the ground?

    Every swing is different. I think more options during the fitting process is a good thing and it’ll make it easier to blend with the t200’s. Don’t see an issue here.

    Or, you can save bank and buy a solid set of 2017 AP3’s which have the exact same specs as the 2020 Turbo generating Double S T1 hunnerd’s!

    Will the nonsense marketing ever end?!! I want the Twin Turbo Super Duper Red SS models due out in 3.5 months! I want a 15 degree 3 iron!! Come on guys, REALLY!!

    I like it cause it blends to the T200 irons better. I’ll take the T200 6(27), T100S 7(32) and 8 (bent to 37), T100 9(42). Throw in my TM PW(47), GW(52), and SW(58).

    Most people carry a 58/60 wedge, a putter, driver and 3w. That gives you 10 clubs to fill on the gap between the 3w and the wedge. Does it really matter what each club says, or that is fits the gaps????

      Equipment is trending toward very individualized customization. Types and number of clubs will vary from player to player.

      It’s a fun experiment to see which clubs are essential & work best for you.

    Why not crank them down as low as humanly possible so I can hit my 7 iron 300 yards?

    This is so dumb. Why do people pay attention to numbers on the head. I can hit my MP-14s just as far and well as this. Who cares if my old 6 iron is a 7 iron today?

      I agree, but golfers have these “things” called ego’s……..and well ya know. And I’ll bet my nut bag that the cat who drives the porche S…..has the biggest ego of them all…..his PW is 41*

    SPIN IS YOUR FRIEND. I don’t understand the search for low spin and strange flight.

    • Alex

      Jan 16, 2020 at 1:25 pm

      Exactly. Its only not your friend hitting driver longer and into wind. I for one like holding greens on par 3s and 4s.

      Spin helps you stop the ball. But there’s a level of over spin that’s unnecessary and actually hurts distance consistency on the green. I don’t want to spin back 9 irons 10 yards, it makes a gap in yardages I can hit to on the green.

      Most players do not want 9000+ rpms on a 9 iron, especially at high launch and decent angles.. 8000 will stop dead at over 45% decent, and give you extra carry yards. That’s why people want to optimize spin.
