What we know about Bryson DeChambeau’s 3D-printed Avoda irons

Published

on

Bryson DeChambeau fired an opening-round 7-under 65 at Augusta National, hitting an impressive 15 of 18 greens in regulation in the process. Golf’s mad scientist’s play grabbed headlines and so too did his equipment. In place of the Ping i230 irons he had in the bag last week for LIV Golf’s Miami event, DeChambeau is gaming a prototype 5-PW set of irons from little-known direct-to-consumer manufacturer Avoda.

What is Avoda Golf?

Founded by Tom Bailey, also a Mike Schy student like Bryson DeChambeau, Avoda Golf is a direct-to-consumer golf equipment company that currently manufactures both single and variable-length irons in one model that are available for pre-order.

What irons is Bryson DeChambeau playing?

Per multiple reports, DeChambeau is playing a custom-designed set of single-length irons that incorporate bulge and roll into the face design. The two-piece 3D-printed irons were reportedly only approved for play by the USGA this week, according to Golfweek’s Adam Schupak.

Regarding the irons, DeChambeau told Golf Channel the irons’ performance on mishits was the determining factor in putting them in play this week. “When I mishit on the toe or the heel,” DeChambeau said. “It seems to fly a lot straighter for me and that’s what has allowed me to be more comfortable over the ball.”

What can we tell about the design of the clubs?

These days, it is a little hard to speculate on what is under the hood with so many hollow body irons. DeChambeau’s irons look to be hollow on the lower section as they do flare back a decent amount. That “muscle” on the back also looks to be fairly low on the iron head, but we can assume that is progressive through the set, moving up higher in the short irons.

A screw out on the toe is probably used to seal up the hollow cavity and used as a weight to dial in the swing weight of the club. From pictures, it is hard to tell but the sole looks to have a little curve from heel to toe while also having some sharper angles on them. A more boxy and sharper toe section looks to be the design that suits Bryson’s eye based on the irons he has gravitated toward recently.

What are bulge and roll, again?

Two types of curvature in a club face, traditionally incorporated only in wood design. Bulge is heel-toe curvature. Roll is crown-sole curvature. Both design elements are designed to mitigate gear effect on off-center strikes and produce shots that finish closer to the intended target line. (GolfTec has an excellent overview of bulge and roll with some handy GIFs for the visual learner)

What else is in DeChambeau’s bag?

Accompanying his traditional Sik putter, Bryson builds his set with a Ping Glide 4.0 wedges, a Krank Formula Fire driver and 5-wood, and a TaylorMade BRNR Mini Driver, all with LA Golf graphite shafts.

    Got to hit these irons (Bryson’s 8 iron) on the range Monday and made a video with them. The bulge effect is legit and I loved how they felt!

    Replace SIK with a P&SI-EGOS and it’s guaranteed Bryson wins a Masters. All provable on any practice green.

    Would love to see him play forged blades and wedges.

Found my unicorn fairway wood – GolfWRXers discuss

Published

on

In our forums, one user has triumphantly declared that at long last, they’ve found their “unicorn fairway wood.” User @Mp14forlife shared the great news in a post outlining their journey.

They wrote:

“This has been a years long struggle. I play 3-pw and carry a 56, 60 and 64 degree. So I only have room for 1 fairway wood. I had been using a 5 wood which was good to about 250ish. My dream club was finding a bigger headed fairway wood that could get out to 270ish but also easy to elevate off the deck and not be too hot but also not balloon either. It’s been a struggle trying to find that. Well I found the right combo after several attempts. I’m hitting the AI smoke max 3hl with a 75 gram tensei blue. This thing feels great, I’ve been able to smooth shots into greens with this thing from 260 and have it stop no problem, even on downhill lies it’s been easy to elevate. I’m able to smash it off the tee as well and not worry about it being too hot, just a great flight and right amount of spin. And that face feels great. Finally nice to have this part of the bag figured out.”

Some members in the forum have offered up support and excitement, while others poke fun at MP14forlife’s “problem.” 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.

  • azgreg: “I’m having a hard time imagining that a 250 yard fairway club wasn’t sufficient. It’s evident that not all of us play the same game here.”
  • alittleoverpar: “Fairways are the hardest to get comfortable with. I’ve tried many over the years but have landed on the 5 Deep as my tool of choice.”
  • BowMain42: “I don’t think there’s anything better than having a comfy fairway wood. Just something about it feels… right. As evidenced by the many pros that rock old, worn ones.”

The Memorial Tournament Lead Tape Report: Get some weight on that putter!

Published

on

The PGA Tour is at the Memorial Tournament this week in Dublin, Ohio.

A few tournament facts: This is the 50th playing of the Memorial Tournament. Jack Nicklaus began hosting in 1976. The most victories of this event is Tiger Woods with wins in 1999, 2000, 2001, 2009, 2012. The lowest score in tournament history came in the second round in 1996 where John Huston fired a 61. This year Scottie Scheffler is eyeing his third win in a row at the Memorial Tournament.

I have been eyeing the bags of the players thanks to GolfWRX photographer Greg Moore. Here was caught my eye from the world of lead tape, plus a couple other notables, in this week’s Lead Tape Report.

Chris Gotterup

The 11th ranked player in the world makes his third trip to the Memorial Tournament. After previously missing two cuts here he is looking for a strong event. When it comes to the bag, we can see some very cool custom KBS Shaft labels with his collegiate past with Rutgers University and University of Oklahoma.

Moving on to the putter, the familiar Spider X1 model for Gotterup. This has been in the bag for his four PGA Tour victories. Full coverage on the bottom and a SuperStroke grip with plenty of wear. This has been in the bag through the ups and downs.

Bud Cauley

Taking a look Bud Cauley’s bag we have a mix of choices at the top end of the bag with lofted fairway woods and a driving iron, blade irons and then arriving at the putter, something tried and true. It is a Scotty Cameron Newport 2 putter in a custom finish with some nice wear on the sole. Also, on the sole is a strip of lead tape spanning the bottom on the putter. The putter is stamped with 340 on the bottom but not without a touch of custom weight to bump it up a few more grams. 

Wyndham Clark

Riding the wave from a scorching putter at the CJ Cup Byron Nelson, Wyndham Clark arrives this week on the prowl for another win. The display at the Byron Nelson totaled in 30 under par for the win. This Ping Scottsdale Tec Ally Blue was in hand for the week including a final round 60. There is full coverage of tape on the sole of the putter, but it appears after some practice, Clark added a few more strips to be safe.

We have seen Clark this year use a few different this season and he struck a hot streak with this Ping. When it comes to the Memorial Tournament, Clark will be attempting his 6th try for the Jack Nicklaus Trophy with his best finish in 2023 with a tie for 12th.

Tommy Fleetwood

An old friend returns with a new look. This week Tommy Fleetwood reunites with his TaylorMade Spider but in a refreshed capacity. This is a new Spider model from the 2026 lineup with the markings from the putter Tommy used during this 2025 season which was capped off by winning the Tour Championship for his first PGA Tour victory.

Our GolfWRX photographer said that Fleetwood thought the lines were too perfect on the traditional style setup therefore asking for the laser rendition of the hand drawn lines from his big finish in fall 2025. With a cherry on top, there is a matching head cover for the design starting to show the beginning of a cult following for this alignment design. 

When it comes to tinkering, I can see the psychology here, you want a new putter, which is the new TaylorMade Spider. But you want the familiar look of the putter you had the success with. With bag wear and use in the conditions, permanent marker is only taking you so far when it comes to longevity on a club being used week in and week out. The best of both worlds here with a fresh take on the putter with the original design lasered on the putter.
