If you've kept abreast of golf equipment news on Golfalot over the last few months, you'll know that Titleist have been pretty busy with the release of their TSi2 and TSi3 drivers, fairways and hybrids.

The fun doesn't stop there, however, as 2021 sees the introduction the TSi1 metals and TSi4 driver to the family, proving the brand's commitment to producing products which cater for every golfer on the market.

Titleist TSi1 and TSi4

In the past, Titleist may have been seen as clubs for the 'better player' but the new TSi range is just as suited to a beginner or older golfer with slower swing speeds than it is to the likes of Jordan Spieth and Justin Thomas on the PGA Tour.

Titleist TSi1 Driver

The TSi1 range as a whole comes with an ultra-lightweight construction which is designed for golfers with a moderate swing speed - less than 90 mph - who seek a little more club and ball speed.

Titleist TSi1 and TSi4

The TSi1 driver has a 460cc head but weights almost 40g lighter than other Titleist drivers, delivering a high launch with mid spin and the most draw-bias in the range thanks to CG positioning.

Altering the head shape allowed Titleist to move the CG closer to the centre of the face, producing more ball speed compared to the original TS1.

Like the rest of the drivers, the TSi1 features the new ATI 425 face, which they claim has resulted in the 'longest, straightest, best-looking and best-sounding' drivers they have ever made.

Priced at £519, the TSi1 Driver is available on pre-sale now and in retailers from March 15th, complete with an ultra-lightweight Aldila Ascent shaft.

It comes in 9, 10 and 12 degrees for right-handed golfers and 10 degrees only for left-handed golfers.

Titleist TSi1 Fairways

The TSi1 fairways continue with the same lightweight setup and come in at almost 50g lighter than standard fairways. This is done by taking 10 grams of weight out of the head, while keeping the MOI at the same level as the TSi2 fairways.

To accomplish that, the CG depth is moved further back in the head which leads to a higher launch. Making the club lighter also helps golfers to generate a little more club head speed, which should generate more ball speed and lead to more consistency with the fairways - something which a lot of golfers struggle with.

The TSi1 features an Aldila Ascent shaft which weighs just 40g, along with a Golf Pride grip. Titleist say that it is the perfect fairway metal option for slow to moderate swing speed golfers.

It is priced at £279 and is available in 15, 18, 20, and 23 degrees in right-handed, and 15 and 18 degrees in left handed.

Titleist TSi1 Hybrid

The TSi1 hybrid has a larger 'wood-like' profile and is engineered to deliver a high launch with mid spin, and features a 455 Carpenter Steel Forged Face.

It has a deeper CG for high MOI and extra stability, along with consistent ball speed across the face.

The hybrid is £245 and ranges in lofts from 20 to 29 degrees. Titleist say that their testing has seen it preferred by moderate swing speed players, as they were the golfers who saw the most increase in club speed and distance.

Titleist TSi4 Driver

At the other end of the spectrum, the new TSi4 driver is designed for golfers looking for ultra-low spin combined with the same ball speed and distance gains provided by the TSi2 and TSi3, which have been the PGA Tour's most popular models this season.

Titleist TSi1 and TSi4

The TSi4 is the driver of choice for the likes of Adam Scott and Russell Henley already, as it is said to provide the necessary spin reduction without golfers having to compromise on ball speed.

It features the lowest CG of any of the TSi drivers, and it is also the furthest forward. This gives the driver less dynamic loft and therefore less spin at impact. A higher MOI gives a higher launch and overall trajectory for more spin.

The TSi4 is also the most workable of the TSi drivers thanks to a small, pear-shaped 430cc head with an improved sound and feel.

It features the same ATI 425 face as the rest of the range, launching the ball with added speed at impact for more consistent results and longer, straighter drives.

The TSi4 has been engineered to reduce drag by up to 6 percent compared to the TS4, encouraging faster club head speed which in turn produces more ball speed and distance.

Titleist TSi1 and TSi4

The driver features Titleist's SureFit hosel with 16 different loft/lie settings, along with headweight adjustability to create a more consistent and optimised ball flight.

The TSi4 is priced at £519 and comes with a choice of two featured shafts - Hzrdus Smoke yellow and Tensei AV White - with other custom options available.

It is available in lofts of 8, 9 and 10 degrees in right-handed, and 9 degrees only in left-handed.
