WRX Spotted: LA Golf Shafts “Rebar” wedge shaft



la golf shafts rebar wedge shaft

Regarding a golf shaft: “It feels like a piece of rebar” is one of those phrases in the golf vernacular. In the case of LA Golf Shafts and its newest prototype being tested on tour, “being as stiff as a piece of rebar” is exactly what the company is going for.

To get the inside information on the new Rebar prototype, we reached out LA Golf Shafts Chief Product Officer John Oldenberg to find the out about the origin and development of the shaft

“The word “rebar” says it all. Our team did some testing with Bryson about a month back in San Diego with the Cobra folks on iron and wedges. At the time Bryson asked if we could make him a graphite shaft that was stiffer than the Dynamic Gold X7 that has been gaming. The answer to him was absolutely!”

This is the biggest misconception that many consumers still have about graphite—it’s not as strong or as stiff as steel, since when it was originally introduced the shafts were targeted as a softer, lighter alternative to steel.

Back to John

“I told Bryson that with graphite, I could make the shaft as stiff as rebar. He was intrigued and ask that we make him shafts to test that were as stiff as we possibly could. So that’s what we did, hence the working name ‘Rebar’.  He tested a ‘Rebar’ 7 iron shaft at Cobra about 2 weeks ago and really liked it, and asked for some wedges to test. 

“The shafts that he is testing now  (that we spotted at the Safeway) are the ‘Rebar’ wedge shafts.  They are at least a full flex stiffer than his X7’s and are a whole lot stiffer in the tip, while also being a bit lower in torque.  So far the response from him has been very positive.  Last I heard he had re-shafted his three wedges with the “Rebar” and was taking them out on the course for a practice round.

“If these shafts work, the plan is to work him into a full set of graphite by the end of the year.”

This is certainly an interesting development since currently there isn’t a single player in the top 20 in the Official World Golf Rankings who plays graphite iron shafts—and the only one in the top 50 right now (based on current bags) is Matt Kuchar. Designers have said for years graphite can be made stiffer and even more reliable than steel, and now we are slowly seeing these product developments make their way to the PGA Tour.

    Bryson is a brilliant idiot who will soon think himself out of golf.

      Really Fred? He got to be a top 10 player on earth with multiple wins on the PGA tour, doing and thinking exactly how he does. But please, enlighten us what he should do differently with his equipment.

    About 25 yrs ago, when graphite shaft innovations were finally yielding some good breakthroughs, one of my students, an engineer (of course) brought me an 8 page print out of all the computations he did and ‘proved’ rebar would be better than any steel or graphite shaft…(as long as you’re Iron Byron)

    Kinda been done with wedges – see ‘Lobster Shaft’…

    I’m in favor of really stiff wedge shafts, but very little tech is required for that 🙂

How defending John Deere Classic champ Dylan Frittelli gained nearly 20 yards



Editor’s Note: We filed this piece for’s Equipment Report.

Let’s begin with some trivia: Looking at the past 10 years, which PGA TOUR golfer has made the biggest distance gain year over year? “That’s an easy one,” you say. “Bryson DeChambeau.” Correct. But who’s right behind Bryson and his 19.8-yard increase in distance from 2019 to 2020?

Who picked up 18 yards off the tee from 2020 to 2021, increasing his average drive from 291 yards to 309?

Here’s a clue: He’s the defending at this week’s John Deere Classic.

While the riddle would have been much more difficult without a headline and image atop this story, it takes nothing away from Frittelli, whose driver clubhead speed is now an impressive 118.7 mph.

“If you hit it 10 yards longer, you increase your prize money by $1 million,” Frittelli said earlier this year, citing statistics. “Things like that are non-negotiable in my mind. It’s fun for me. It’s re-invigorated my game. I’m excited to hit tee shots and see how I can play holes on golf courses differently. Not going full bore, just adding a little speed training in certain situations.”

After doubling down on his fitness — “two solid years of lifting,” according to Frittelli — he wasn’t seeing his increased strength translate to a boost in distance.

“Basically July last year, I looked at my trainer and I said why am I not hitting it any longer? I’ve been doing all these power workouts, strength workouts in the gym, and I’m getting stronger for sure because I can see my PRs moving up in each exercise. I then figured out that he said to me you actually want to hit it further? I didn’t realize that. Yeah, so we switched that up had a little more speed in the workout, so instead of just power and strength, trying to lift heavy and lots of reps, went down to fewer reps and lighter weight.”

In addition, the South African has made some interesting adjustments to his driver setup. And as this is the Equipment Report, we wanted to get more information on the artillery the bomber-come-lately is employing.

We spoke with Callaway’s PGA TOUR manager, Jacob Davidson, to learn more.

GolfWRX: When did the discussion about switching to a longer driver shaft begin, and what was that process like to get him into his current setup?

JD: It started last year. His driver cracked and he put the same model with a new shaft in play at THE CJ CUP @ SHADOW CREEK. We did some more work the next week at the ZOZO CHAMPIONSHIP @ SHERWOOD, and we moved him into a Callaway Mavrik Sub Zero D head that was a little bit wider. We did a bunch of testing at that point with different shafts, tipping. He played the Mavrik Sub Zero D through the fall. Around the Farmers Insurance Open, he did some new testing with the Epic Speed and did some more testing at the Waste Management Phoenix Open and ended up putting the Callaway Epic Speed Triple Diamond LS in play for the PGA Championship with a 46-inch Mitsubishi Tensei AV White AV 65 X tipped 1.5 inches.

The head was a natural fit. His misses had been a little right. With this head, he got lower spin with a more neutral start line. It has a little weight back so it’s more forgiving. 7.6 degrees of actual loft. N-1 hosel setting.
