One of the PGA Tour’s hottest new mini drivers is coming to retail.
On Thursday, Callaway officially announced the Quantum Mini driver, along with the Quantum Ti fairway, bringing the third generation of the company’s mini driver to market, which has proven to be their most versatile based on PGA Tour usage.
The new mini driver borrows from Callaway’s recent fairway wood offerings with a step-sole design, allowing it to be more easily hit off the deck.
“The one thing that you constantly get feedback on is, ‘I can’t hit it off the ground,'” Callaway VP of product strategy Jacob Davidson told GOLF. “And so that was something that we felt like — if we could find a way to help the best players in the world or the average consumer at least be able to hit it off the ground in some capacity, it would just make the product better.”
Meanwhile, the Ti fairway adds left-to-right CG adjustability for the first time in a Callaway fairway wood.
“The benefit of Ti is the amount of discretionary weight that you have to move around,” Davidson said. “And the engineering challenge is like, where do you put it? You have all this tungsten in there, so a lot of time was spent on how do we strategically set this up in a place that delivers a spec package that performs.”
Both clubs launched on the PGA Tour at the AT&T Pebble Beach Pro-Am and have seen a host of player conversions, including Callaway staffers Min Woo Lee and Max Greyserman, and non-staffers like Justin Rose. With several Quantum Minis in bags, Callaway had 10 mini drivers in play at the Masters, the most in the field.

What’s actually new with Quantum Mini and Quantum Ti — and why you should care
A step in the right direction
At 340 cc, the Quantum Mini, like its predecessors, is the largest mini driver in the marketplace. With that comes superior forgiveness off the tee but sacrifices performance from the deck.
Knowing that being able to hit a mini driver off the floor is crucial to players like Si Woo Kim, Callaway borrowed technology from its fairway woods in the step-sole design to help raise strike points on shots hit from the turf.
“Typically, when you try to get these drivers off the ground, you’re so low on the face that you can’t get any launch or spin,” Davidson said. “But the way the step sole works with the turf interaction, you’re able to move that impact location significantly higher on the face.”
High strike points mean lower spin rates off the turf, easier launch and longer distances.
Like the rest of the Quantum driver family, the Quantum Mini has the new multi-material Tri-Force face to boost speeds and aid in spin retention.
Optimizing ball flight
Both the new mini and the Ti fairway wood feature ball flight adjustability through Callaway’s Optifit 4 hosel adapter.
The new hosel was added to all fairway woods this year after just being used on hybrids in the last generation and allows for loft and lie to be adjusted independently. Not only does this allow the mini driver to continue using Callaway 3-wood shafts, but it also helps optimize turf interaction.
“You have more adjustability in lie, right? You can go up and down, flatten, upright,” Davidson said. “And when you get into the mini driver — it’s a shorter build length — so you want to have that adjustability. Especially for the people that are hitting it off the ground, anytime you’re interacting with the ground, lie angle is very important.”
Designers have also gone back to the configuration on the Paradym Ai-Smoke Mini driver of having front-to-back CG adjustability as opposed to having left-to-right CG adjustability on the Elyte Mini. They found most people will benefit more from being able to adjust launch and spin to maximize distance with a mini rather than shot shape.
Meanwhile, with the discretionary weight saved by the titanium construction of the Ti fairway, Callaway chose to give that club left-to-right CG adjustability.
The default position is the heavy weight in the heel to help players create a draw ball flight that most players prefer for a fairway wood.
The Quantum mini and Quantum Ti fairway
Quantum Mini
What is it: A larger 340 cc mini driver featuring Callaway’s Tri-Force face for increased speed and speed retention, step-sole design for turf interaction and forward and aft CG adjustability.
Available lofts: 11.5˚(RH/LH), 13.5˚ (RH/LH)
Who it’s for: Players looking for a forgiving mini driver that can still be hit off the deck to replace a 3-wood or a secondary tee option to their driver.
Quantum Ti fairway wood
What is it: A mid-sized all-titanium construction fairway wood with the footprint of the Quantum Max fairway, but the shape of the Quantum Triple Diamond. Heel-toe weighting allows left-to-right ball flight optimization.
Available lofts [only for woods]: 15˚ (RH/LH), 18˚ (RH only)
Who it’s for: Players who want as long a 3-wood as possible to potentially be used as a secondary tee option or a club to reach longer par-5s in two.
My take: Keep making tee clubs more versatile
I’ve been skeptical of the road Callaway has taken over its initial mini driver releases, but I can say with confidence that the Quantum Mini is leaps and bounds ahead of the others for one simple reason: the sole.
The sole of a mini driver is so important if you’re going to be able to hit it off the turf, so to see technology aimed at helping you get the meat of the club on the ball is a great addition.
I previously thought Callaway mini drivers were too large, thus making them strictly tee clubs, but now they can have their cake and eat it too with the extra forgiveness of the size and the versatility of the sole.
With the Ti fairway wood, this is a club that could rival the Quantum Mini for many players’ bags. It’s basically a question of which look do you want, a more traditional fairway wood that will have a slight edge off the deck, or a mini driver that holds an edge off the tee.
The Ti fairway wood was super easy to launch for me, but it had a very pleasing flat trajectory without me having to do much adjusting of the cog. As someone who lives out on the toe, being able to put weight out there and straighten my ball flight was a huge advantage that just isn’t offered by many other fairway woods with this shape.
Either way you go, Quantum Mini and the Ti fairway wood are going to get you in the short stuff and are easy to hit from there too.
