Players Distance Driver

Mizuno's ST-X 240 occupies an interesting spot in the 2024 driver market. It's aimed at players good enough to notice when a driver isn't honest with them, but practical enough to want some help with launch. At 460cc, it uses every cubic centimeter the rulebook permits, and it pairs that volume with a high-launch design that gets the ball up faster than Mizuno's lower-spinning ST-Z option. This isn't a beginner club wearing premium branding. The Players Distance category means Mizuno is building for someone who already has a swing worth rewarding.

The adjustable hosel deserves more attention than most golfers give it. Plenty of players buy an adjustable driver and leave it at the factory setting indefinitely, which wastes the feature entirely. The ST-X 240 offers real loft flexibility, and finding the right number for your angle of attack is often what separates a driver that works from one that just looks good in the bag. If you tend to come into the ball steeply, you probably need more loft than you think, not less.

Feel matters to Mizuno in a way it doesn't to every driver brand. That reputation comes largely from their irons, but the ST-X 240 carries some of it to the tee box. The forged titanium face produces a sound and sensation that a lot of cast competitors don't match. Whether that registers as meaningful to you or whether you focus on ball speed numbers is personal, but for some players it's exactly why they're standing in front of a Mizuno rack.

• A mid-handicapper with moderate swing speed who consistently loses carry by launching too low and wants a head built to correct that without switching to a game-improvement club.
• A better player coming from a tour-style low-spin driver who has decided the occasional workability gains aren't worth the distance they're giving up.
• Someone who wants Mizuno's build quality and feel at the tee box without the ST-Z's less forgiving spin characteristics.

Frequently Asked Questions

What's the difference between the Mizuno ST-X 240 and the ST-Z 240?

The ST-Z is built for players who want low spin and a penetrating ball flight. It punishes mishits more and rewards precision. The ST-X uses deeper CG placement to boost launch and spread performance across more of the face. Same premium construction and materials, different philosophy about what the average shot in your round actually looks like.

What loft should I play in the Mizuno ST-X 240?

Start at 10.5 degrees unless you have a fast swing speed and a positive angle of attack, in which case 9.5 might be the right base to adjust from. Most players under 100 mph launch their drives lower than optimal and gain distance by adding loft, not removing it. The adjustable hosel lets you fine-tune from there rather than committing to a fixed number.

Is the ST-X 240 forgiving enough for a high handicapper?

It's more forgiving than the ST-Z, but the Players Distance positioning tells you something. Mizuno built this for players who already make reasonable contact and want to optimize from there. If you're a high handicapper looking for maximum forgiveness across the whole face, there are purpose-built options that would serve you better.

How much loft adjustment does the ST-X 240 hosel offer?

The adjustment range covers roughly four degrees total, with some face angle variation built into certain settings. That's enough to make a real difference in your launch and spin numbers. It's designed for dialing in your optimal setup, not compensating for a swing issue, so pair any adjustments with honest data from a launch monitor.

Does the ST-X 240 have a draw bias?

No. It's a neutral head. Mizuno built it to go straight when you swing straight. If a consistent slice is your problem and you want built-in correction, this isn't the answer. It rewards players who have their path and face angle under reasonable control and want to stop leaving distance on the table.
