Nike’s new golf balls have larger, softer resin cores



In 2012, Nike released a new line of golf balls called 20XI that featured a new lightweight core material called RZN (resin). According to Nike, the lightweight resin cores moved more weight to the perimeter of the ball, increasing MOI to make the balls more stable in the wind. The problem was, the golf balls spun too much on iron shots, causing control problems that negated the ball’s higher MOI.

Rock Ishii, director of product development for Nike Golf, said that the company has solved that problem with its 2013 20XI golf balls. Like last year’s models, the new balls have four layers and a urethane cover. But the new models feature a construction with a larger, lower-compression RZN cores that decreases iron spin and allows for even more weight to be moved to the outside of the ball for an even higher MOI.

According to Ishii, one of the main advantages of the 20XI ball is that its high-MOI construction causes less spin decay after it reaches its apex. This means that the 20XI will to spin more consistently than lower MOI golf balls, which will help stabilize their flight during the critical period between apex and landing.

The new 20XI golf balls are available in two models — the 20XI and 20XI X. The difference between two is that the 20XI X has a cover that is six compression points firmer than the 20XI. This will make the 20XI X spin less than the 20XI from driver to wedge, making it a better option for certain golfers with high swing speeds. The street price of both balls is around $46.

Along with the 2013 models of the 20XI, Nike has also released its One RZN golf balls, which offer a lower price point that the 20XI golf balls.

The One RZN balls feature a RZN core and have a compression of about 60 — 20 points softer than the 20XI golf balls. That makes them a good choice for golfers with slow swing speed. The One RZN balls are available in two models — One RZN  and One RZN X — and will retail for around $30.

Like most non-premium golf balls, the One RZN balls have surlyn covers that producs less spin around the greens than balls with urethane covers. Watch the video interview below with Rock Ishii and Zak Kozuchowski for more information on the One RZN balls.

    Less side spin is good for a 12 handicapper. But the amount of total spin they need is dependent on their launch conditions and preferences.

    Players with slow swing speeds can benefit from more spin because it keeps the ball in the air longer for more carry. Players who slice and hook the ball like low spinning balls because the don’t slice and hook as much.

    So Zak, RE: “This will make the 20XI X spin less than the 20XI from driver to wedge, making it a better option for certain golfers with high swing speeds. ” The 20xi ball would be better for a player with a driver swing speed of 92? But isn’t spinning less a good thing for a 12 handicapper?

SPOTTED: New Callaway Forged irons… Apex or Legacy?



Photos of a new Callaway Forged iron popped up in our GolfWRX Forums, and our members are trying to figure out whether they’re going to be replacements for Apex Pro irons, or whether they’re an update on the Legacy series. They could also be X-Forged irons, but since Callaway recently came out with new X-Forged irons, that would be unlikely.

Here’s what GolfWRX Members are saying:

  • elwhippy: A new Legacy iron? Looks a bit Japanese shaped. 
  • mattTHEkatt: Like an X-Forged/Legacy Black mashup. They look powerful. 
  • DTown3011: …gotta be the next Apex!
  • J13: Pics look like a newer legacy black.
  • mgholda: Pics look like a newer legacy black.
  • TheMoneyShot: I thought Cally was going to phase out the Apex name after they released the MBs?
  • john443: A larger cavity in these then the X- Forged… competitor to the 750 and AP3 maybe? …or Legacy Black finally brought to retail…hallelujah. CF16 replacement???!
  • Equipto: These look very sharp, and like thumpers. I don’t care if they are a Legacy Black or Apex replacement, call them whatever… i’ll try them 
  • mrmikeac: Next gen Callaway Apex Legacy? Hmmmm…..
  • Brizam: The Legacy Black might be the best players cavity back ever made.  If they were to become available they’d move straight to the top of the list of clubs to buy for me. 
  • Jourdan M: This is the Apex Pro 

Here are photos of the new Callaway irons we spotted

Wilson’s new FG Tour V6 RAW irons (yes, they will rust)



Wilson came out with its FG Tour V6 irons in 2016, but these new Raw versions have a different look… and with time, they’ll have a VERY different look.

The new FG Tour V6 Raw irons have an unplated finish, and they’re designed to “develop a unique patina based on age, exposure and use over time,” according to Wilson. This gives each iron a unique look, and one that’s far from the clean cut original FG Tour release that had a chrome finish (which won’t rust).

In addition to the rusting effect, the irons are different because they have a copper badge in the cavity that will eventually match the color of the golf club over time. Here’s a graphic mock-up of how the Raw irons may look overtime.

Like the original releases, the irons have tungsten weights and mass behind the impact area for a “forged feel” and “improved feedback,” according to the company.

The FG Tour V6 Raw irons are a custom option on, and are available through Wilson’s premium partner accounts as of today, Tuesday, June 19. According to Wilson, the Raw irons “are a very limited production run,” so only a certain amount of sets will even be built.
