Max Game Improvement Driver

The TSi1 is the lightweight member of Titleist's 2021 TSi driver family, and it exists for one reason: to help golfers who don't swing fast get more out of every drive. Titleist trimmed weight everywhere, in the head, the shaft, and the grip, so the whole club comes in noticeably lighter than the TSi2 or TSi3. That ease of swinging turns into more clubhead speed for players who can't muscle a standard driver.

It shares the ATI 425 titanium face with the rest of the TSi line, so you aren't getting a watered-down version of Titleist's speed tech just because the club is light. The 460cc head sits squarely in the max game improvement bucket, with a high-launch profile that gets the ball airborne without a fight. Forgiveness on mishits is built in, which matters when your contact isn't dead center every time.

This is a driver for seniors, slower swingers, and anyone whose tempo has settled down but still wants a Titleist in the bag. It won't turn a 90 mph swing into a bomber. For players in the 70s and low 80s, though, the lighter package can add real yards you've been missing.

• Slower swingers, roughly in the 70s to low 80s in mph, who need help generating clubhead speed
• Senior golfers who have lost distance and want a lighter club that's easier to swing fast
• Players who want a genuine Titleist driver without the heavier build of the TSi2 or TSi3
• Anyone fighting a low ball flight who needs more launch and carry off the tee

Frequently Asked Questions

How is the TSi1 different from the TSi2?

The biggest difference is weight. The TSi1 uses a lighter head, shaft, and grip so the whole club is easier and faster to swing. The TSi2 is a standard-weight game improvement driver aimed at moderate to faster swings. Both share the same ATI 425 face and 460cc head, but the TSi1 is built specifically for players who need help creating speed.

Is the TSi1 a good driver for seniors?

Yes. It's one of the better picks for senior golfers whose swing speed has dropped. The lightweight build helps you swing faster with the same effort, and the high-launch design gets the ball up and carrying, which is usually where slower swings lose their distance.

What swing speed is the TSi1 designed for?

It's aimed at slower swingers, generally under about 85 mph with the driver. If you swing faster than that, you'll probably get more from the TSi2 or TSi3, which are built to handle higher speeds without ballooning the ball flight.

Is the TSi1 adjustable?

Yes. It has Titleist's SureFit hosel with 16 independent loft and lie settings, so you can fine-tune launch angle and face angle. There's no movable sole weight like you'll find on some drivers, but the hosel gives you plenty of room to shape ball flight.

Can I put a heavier shaft in the TSi1?

You can, but it works against the point of the club. The TSi1 is engineered around a light overall weight to boost swing speed. If you want a heavier shaft, the TSi2 is the better platform since it's designed for that kind of build.
