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.

What’s the perfect mini-driver/shaft combo? – GolfWRXers discuss
In our forums, our members have been discussing Mini-Drivers and accompanying shafts. WRXer ‘JamesFisher1990’ is about to purchase a BRNR Mini and is torn on what shaft weight to use, and our members have been sharing their thoughts and set ups 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.
- PARETO: “New BRNR at 13.5. Took it over to TXG (Club Champ but TXG will always rule) in Calgary for a fit. Took the head down to 12, stuck in a Graphite Design AD at 3 wood length and 60g. Presto- numbers that rivaled my G430Max but with waaaaay tighter dispersion. Win.”
- driveandputtmachine: “Still playing a MIni 300. The head was only 208, so I ordered a heavier weight and play it at 3 wood length. I am playing a Ventus Red 70. I play 70 grams in my fairways. I use it mainly to hit draws off the tee. When I combine me, a driver, and trying to hit a draw it does not work out well most of the time. So the MIni is for that. As an aside, I have not hit the newest BRNR, but the previous model wasn’t great off the deck. The 300 Mini is very good off the deck.”
- JAM01: “Ok, just put the BRNR in the bag along side a QI10 max and a QI10 3 wood. A load of top end redundancy. But, I have several holes at my two home courses where the flight and accuracy of the mini driver helps immensely. Mine is stock Proforce 65 at 13.5, I could see a heavier shaft, but to normal flex, as a nice alternative.”

How much does the TSi1 weigh? It says 40 grams less, is that head weight?
