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 🙂

Forum Thread of the Day: “Courses that are now obsolete on Tour due to power in the game?”



Today’s Forum Thread of the Day comes from Titleist99 who asks WRXers if they feel some golf courses are now obsolete on Tour due to the ever-growing power element in the game. Some of our members list tracks which they think will struggle to host majors again, while others explain why they feel every famous course still has its place on the calendar.

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.

  • oikos1: “The courses aren’t obsolete because most fans enjoy seeing a course overpowered. Golf traditionalists may not like it but just look at other sports today. Sure, a no-no, once it gets to the 7th becomes interesting, but most fans want to see homers and runs scored. Same in basketball, no one wants a pro game ending at 60-54 and football clearly is shooting for high scoring passing affairs. The majority of golf fans just don’t want to watch pro’s grind it out every week. They want to cheer for birdies and eagles. They want to see if the impossible is possible, the potential for crazy good. Bring on the 54 in golf! So no, golf courses aren’t becoming obsolete. PGA Tour attendance has been on the rise the last three years. If anything, they are looking at ways to make the events bigger and will seek venues that allow for just that.”
  • LICC: “Some former Majors courses that are now too short for the majors: St. Louis, Canterbury, Northwood, Prestwick, Myopia, Five Farms, Wannamoisett, Chicago Golf Club.”
  • Obee: “The problem with the shorter courses is that the Tour players don’t like having driver taken out of their hands. And that’s really all it is. They get ‘bored.’I get it; it does take away a large part of the game. But I would love to see them play more short courses were drivers taken out of their hands on a good number of holes. But as far as ‘obsolete’ goes. None of the courses are obsolete. They are just different.”
  • NJpatbee: “Course design and not just length add to the difficulty of a course. Pine Valley will never host a pro tournament because of their inability to handle the crowds; I would speculate that even the regular tees would be a challenge for the PGA Tour pros. The Championship Tees would be a bear. Now, I have never played there, but I am available if any member wishes to invite me!”
  • Titleist99: “PGA TOUR might want to add a little rough to protect our classic courses..”

GolfWRX Spotted: Prototype Callaway Apex MB



Callaway Prototype blade 2020 MB

“Its the most wonderful time fo the year” I’m talking testing and prototype season on the PGA Tour as we head into the winter break. At the RSM Classic, we spotted what looks to be some early Callaway prototype irons in the bag of Aaron Wise.

We’ve seen a few different Callaway Prototype MBs in players’ bags this year including a “special Japanese forged” version made for a few players, including Open Championship winner Francesco Molinari, and more recently, Maverick McNealy.

The new Prototype MB/Blade has all the telltale signs of a traditional Callaway-shaped blade including the thinner hosel-to-top transition—also known as the crotch of the iron—rounded lines, high toe, and short heel-to-toe length. What makes it a unique Callaway iron, of course, is the noticeable screw in the back of the head behind the center of gravity.

This design feature is not new, and for many gear junkies probably brings back memories of the original Adams Pro Black MB irons or the 2011 TaylorMade MBs.


By using a weight screw instead of traditional tip weights to get the club to spec, there is zero chance of moving the center of gravity horizontally towards the heel of the club. It helps add mass to improve feel. In most cases, a blade/MB iron from any OEM is built as a showpiece in a classic design. If we are looking at the new Apex MB from Callaway as a potential release in 2020, sticking to a classic style can be a great thing.
