Nike RZN Tour and RZN Speed golf balls

Published

Since the birth of the modern golf ball, there have been hundreds of thousands of different arrangements, styles, numbers, patterns and geometries of dimples. They’re a golf ball’s fingerprint, and that fingerprint plays a role in exactly how a golf ball will fly toward its intended target.

Figure 1

One look at Nike’s new RZN Tour golf balls and you’ll notice something odd; each of its dimples has dimples — 344 standard-sized dimples, and 13,558 smaller “micro-dimples.” Nike claims that the microdimples, which look like shallow pin pokes, reduce drag to improve aerodynamics. According to Nike, the micro-dimples are placed strategically around the ball, and improve lift and drag properties, especially at the end of the ball’s flight.

With the new line, Nike has also re-engineered its familiar RZN cores and the inner layers of its golf balls.

Nike’s two new RZN Tour golf balls (RZN Black, RZN Platinum) have four-piece constructions and urethane covers, and their new RZN 4.0 cores have been made 10 percent larger than previous models. Using more of the lightweight, RZN material in the design helped the company redistributed weight to the outer layers of the golf balls, increasing moment of inertia (MOI). With more MOI, the balls will fly straighter for the duration of their flight, reducing the effect of wind, according to Nike.

Figure 2

A graphic from Nike shows the microdimples (left) and how the RZN 4.0 core behaves at impact.

The new RZN 4.0 core is also said to make the ball softer, without sacrificing distance.

“The ball feels much softer, yet I’ve maintained my ball speed and even picked up a few yards overall,” Rory McIlroy said. “It’s easily the best combination of distance and feel I’ve ever played.”

The inner cores (pictured in blue in Figure 2) uses deep grooves and X’s on its surface to provide 26 percent more surface area contact than its predecessors for more efficient energy transfer from club to ball. The Speedlock Mantle (the yellow layer in Figure 1) also has similar “Speedlock” technology, which reduces slippage with outer layer of the golf ball and adds approximately 150 rpm of spin on approach shots, according to Rock Ishii, Nike Golf’s Senior Director of Innovation for Golf Balls.

The RZN Tour golf balls are for golfers looking for the ultimate in distance, feel and control. The RZN Black, which new Nike athlete Tony Finau will play, offers lower spin with a golfer’s longer clubs for more distance, according to Nike. The RZN Platinum offers slightly more spin and is “designed to Rory McIlroy’s exact specifications,” according to Nike.

For the golfer looking for a softer feel at a reduced price, Nike also has new RZN Speed golf balls.

RZN Speed (Red and White)

Nike’s RZN Speed golf balls have a three-piece construction, and are for golfers who desire a soft golf ball, or a lower price-point model. The balls have an even softer RZN core, according to Nike, and the same Speedlock X technology used in the RZN Tour balls to maximize energy transfer.

The RZN Red ball offers more distance, while the RZN White ball concentrates on a softer feel. Both the RZN Tour and RZN Speed golf balls will be available at NikeGolf.com on January 22, and at select retailers on January 29.

Slab city on the Korn Ferry Tour — Lead Tape Report

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.

Joel Thelen

Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.

First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.

Mitchell Meissner

Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.

@Lamosteve began:

Can you name every set of irons you’ve owned? Here’s mine

Spalding Dots
Spalding Eclipse
Ram Lazer FX
Lynx Parallax
Mizuno EZ Comp
Ben Hogans
Cleveland CG Red
Taylor Made R9s
PING i20
PING iE1
Taylor Made M6

Our members in the forum have been offering up their own collections. 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.

macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”
JimmyC59: “MacGregor Jack Nicklaus Triple Crown. Palmer The Standard. Still play these.”
jgrzask: “Tommy Armour 845u
