You guys should have Bryson on the show. I bet he'd come out and talk specs with you all, he's a huge gear nerd.
That would be fantastic - and can see Bryson enjoying this as much as the TXG boys but nowhere near as much as us 😊
Very good suggestion. It'd be a treat, though we'd maybe need a nap afterwards...
That would be amazing!
This is the best idea I have ever heard of. Ian, reach out to him!
100% reach out to Bryson cause the insight you would get would have so many views
Finally a throwback video of what TXG used to provide your audience, I love the new gear but I especially love the gear talk. Cheers guys trip down memory lane with this video cheers guys
This is they type of content that made txg blow up in the first place, flexing golf technical knowledge and all us nerds eating it up.
100%
Feels like cheating getting this information for free. Never had a lesson but I’m sure these guys helped me reduce my handicap from 18 to 0 in 4 years 🎉
I would love to see a "scientific" series where Ian uses slow motion video to explain some of these things. I love to nerd out and I'm sure there's a bunch of viewers who would like to see that.
Bryson is my favourite golfer and personality. His YT is more fun and interesting than any tournament.
As someone who wasn't around during the old TXG days, I'm totally here for this type of video. It's encouraging seeing all the comments under the video talking about this is what TXG used to do. Keep putting out the technical stuff every once in a while. It's a super interesting watch.
As a golf nerd, I really appreciate this content. Keep up the good works lads!
Thank you for touching on this matter. I think it is a great time to dive into the single-length iron topic again. Thank you!!
And MOI matching. Single length sets are all the same MOI from the grip end of the club. There are huge advantages to this but you can match MOIs of standard set too.
ive always wanted to try this setup but i dont think the average fitter has the ability to accurately fit, swing weight, and loft each iron to the specs needed to have accurate gapping..
One of the most interesting things that has come out of the LIV split is what gear those guys are playing now that the sponsorships are gone. I've noticed some interesting choices, like Phil using a LAB putter and how many guys choose PING products without a sponsorship. You get some insight into what gear a pro really likes, instead of who's paying them.
Their sponsorships aren't gone. Some may have lost them but most are still affiliated to the same brands as before.
Bryson using ping until last weekand and he's not a listed sponsored player for them . I do believe there are a few Pros using gear they aren't paid too. As far as the big names go in liv. I don't know forsure
@@sandersson2813Exactly, they’re not gone, but it’s probably more likely that they now have so much guaranteed money that when their contracts end, they choose freedom over signing with an OEM.
@@Matthew-of9sp
It looks as if LIV will have paid off their clothing/hat sponsors, but clearly they still have show sponsors and club sponsors in the main.
Haven't seen many of them diverge from what they played on PGA.
Bryson is a Rockstar, get him on the show please
Would love to get together with Bryson to talk about gear.
A good friend of mine works for LIV golf and has spent a lot of time chatting with Bryson. He says Bryson is a really good guy and fun to be around. I love him!
Any chance he can get me some of those heads? Being dead serious haha
@@ForzaOwnz that’s likely way above my status in all of this :)
@@Huntgolfride
Awh so it’s a friend of a friend of a friend 😂😂😂😂
@@jpxst180s6 No, its a friend, and a good one, but Im pretty sure the ask from this far is out of reach:). I went to their website, actually not a bad price, although at my swing speed, completely useless for my game.
I used to think he was a douche bag but been watching his you tube channel last 6 months really changed my mind on him he seems a really good guy
Now this has to be The Best video on golf physics i have
Ever seen. Well done, Ian!!!
And Bryson is the only LIV player i like and will watch.
I've been watching your content for years and I'm happy to say I thoroughly understood every point being made in this video. Cheers to Fraser University
We need a golf nerd series! You guys have in-depth knowledge that very few possess. Let it shine!
Love the physics of this.
Past few years I have really started to nerd out and get real into the equipment, science, how and why certain things fit certain people. You guys have really fed my want to know more and I love it. This was awesome. Keep it up!
Great video and explanations thanks for more great content for us total golf nerds.
I’ve been watching a bit of Bryson on RUclips and he uses strike location to shape his shots. He wants to keep his swing exactly the same every time. So in order to shape the shot he adjusts his strike location. When watching his RUclips you will hear him say “I want this to draw so I’m gonna hit it on the toe”
He says this mostly with driver but I’ve noticed him also do it with irons.
So I think this has less to do with trying to hit it straight and more that Bryson wants a swing we can hit exactly the same way every shot but still get the shape out of the ball that he wants.
Everyone focuses on his swing speed but in this case I think this is more about his single plane swing and him applying the scientific method to get repeatable shots that don’t rely on feel.
He’s dialed in every swing the same with repeatable changes. He knows exactly how far a 60 degree wedge will go based on the clock method to 15 minute intervals. He knows exactly how far his putts go based on how far he takes back his club. He measures everything precisely on the golf course.
So unlike most equipment that is designed to hit straight with off center shots, Bryson actually wants shape with different strike locations. This is why his equipment doesn’t work for regular players and not necessarily his swing speed which has been more and more common on tour.
I think you nailed it right here.
You guys did an excellent job explaining that!
Don’t need a nap. This is the kind of stuff I love. More of the same please!! Great job.
Let’s go!! More nerdy videos!!
This is pure gold....thank you guys!
Imagine paying to be a member 😂
Excellent video guys! Appreciate the gear talk. I am definitely a golf nerd and really enjoy these technical discussion. I look forward to the review of the Avodoa irons one day. great stuff!
really interesting, thanks guys
You guys should reach out to Bryson. He LOVES sharing the technical end of what he’s doing. Get him on the channel to break it down with you!!
Great content guys again 👏🏻
Awesome. I like how Bryson is willing to push the norm.
Wish I could “Love” this video. Ian at his absolute best! Mikey appropriately impressed.
Had these guys kept the TXG name and put out more shows like this one there’s no telling how big their channel would have gotten ! Great show guys !
Great video. Im sure it won’t be your most popular video but the science you dive into is excellent!
Really good! Anyone who understands the swing numbers will get this video. Thank you for doing it.
Very good explanation at the start
I’m lovin the content guys !
Damn didn’t think I’d be back in geometry and physics class this early in the morning… I need my coffee first…
Very interesting! I honestly think that it could help a bunch of golfers.
I love the science. So interesting
Really enjoyed that. And yes, I’m a golf nerd.
Great video boyz!
Would like to see a video with you all using different iron lofts with same shaft length to see impact on distance. That is also a huge part of Bryson's irons.
Fascinating.
Love the tech talk
💙, we enjoyed this one also!!
At what swing speed should you consider a driver head to “too much” bulge and roll? Because I’m around 120 mph driver head speed which is above average but no where near Bryson’s.
At BDs swing/ball speed, his shots are doing things us normal players can't fathom. Makes sense why he would want horizontal roll to help with miss hits. Love how he never stops tinkering and searching.
I noticed the curve on my driver face as a kid and intuitively tried to figure out why it was like that. I thought hitting the toe or heel would cause opposite spin than it actually does. Based on the face to path youd think it would curve right for a toe strike for a righty, but bc of the rebound of the face opening up it emparts opposite spin and the thing i thought would make it spin right just gives it a slightly right initial start line. I honestly thought of this and thought why dont they have concave club faces? But i had the physics opposite
good stuff boys....
I like to talk about the gear effect like pitches that a baseball pitchers throws over the plate. Lots of different ways to get there when dealing with spin axis from a particular start location of the hand.
So cool. Have you done a video with the Krank driver
currently gaming a older adams DHY 21 degree hybrid with the buldge/rolled face. not a super fast swinger but can feel it helps on off centre strikes!
Thanks for going over this, always been a big nerd like Bryson, just a really poor golfer.
Need part 2 on this video after bryson took 2nd at the PGA. Get Bryson on or the guy from Avoda to talk more detail on it. Would be sick to have bryson in studio to demonstrate exactly what hes going for and why its working for him
Love my Krank Fire driver. Definitely something to the bulge and roll helping its accuracy.
I love the gear head nerd talk! The weeds are the place to be!
Damn I’m a super golf nerd eh I was loving that
Will you be doing the S159 wedges anytime?
Been using the krank fire pro 7.5 Deg and it's amazing!! Swing around 132 average and it's better than all I've tried so far. Very straight and ball speeds are incredible on monitor 🤙
Should get one in to test, I think Mr Fraser would be in heaven, colours match well with the VF 😉💣
I second that this would be a great video to see
So what would a slow swing speed produce? I assume that over corrects those bad shots off the heel and toe.
I have an old Controller 1 iron that has a curved face and it does seem to shape the ball more than my normal driving iron.
Can't wait to see the new Cobra's printed
Anyone else remember the Wilson 1200 GE (Gear Effect) irons from back in the day?
Would be awesome to deep dive on Avoda irons and why Bryson’s irons are different from production set available from avoda.
Questions:
What iron ball speed is gear effect on irons effective?
What loft does h-convexity make sense? Does it make sense of wedges short game?
Does trampoline effect (smash) of players or cavity iron contribute to need for roll and bulge or does a more springy face take care of some gear effect rendering roll unuseful?
Ian, do you know what the iron lie and loft settings for the single length club design you talked about would be? I really can not figure out, via the science, if the loft or lie would need to be stronger or softer. Thanks
I'd love to know too.
His Ping irons before the Avoda's had a 5i at 17* (my 2 iron). He wanted it stronger but the heads would break in the neck. 9i was 37*
Hope they follow up on this.
Can't find anything on lies. I'm guessing 69-70*.
@@paulcarrigan691 I think Avoda's current offerings for one-length irons are pretty awesome for us mortals, even with higher swing speeds. There's literally zero reason for a 17* 5 iron for the rest of us
@@BigDawgCAM That's fine. No idea what relevance your comment has to mine.
I really don't understand gear effect. When my club face is open the ball slices. So how does having the face more open on the toe make toe strikes go left? I don't get it.
I love my one lengths, I play a Radspeed set in the winter and Forged Tec set in the spring+. Golf never completely stops here in Tennessee, at least for me raised out west, these Southern dandies hang it up when it gets below 60. Shit, it's still shorts weather anywhere above 40. Would love to see a review of the Avoda "Same Length".
so interesting. Again, these guys are playing a completely different game than the rest of us.
Could this help explain the BRNR Mini’s insane fairway finding abilities? A 3w with bulge on a larger face 👼
Woods and hybrids have bulge and roll as well. It would be more pronounced in the mini driver because it is a larger head and would impart more gear effect though.
T-shirt slogan - FRAZZLED by Fraser.
😂😂😂, sorry about that!! 🤯
What's key to any of the things Bryson is working on it involves his swing speed, which very few if any of us actually have
The best part of Bryson's contribution to golf is the CLEAR separation between us mortals and a dedicated professional athlete. (There's a few players on the tour that make me think; "hey, maybe I can do that ...")
The physics in play for that level of golf are nothing but theoretical for the rest of us.
um no, it didn't take "Bryson" to realize the level of dedication of top athletes
@@BuffaloNickel9 Nobody said anything about realizing anything.
Players like "Bryson", Tiger, and Jack are a danger to the gentle game of golf. Moving the goal post of golf physicality at the elite level, often destroying their bodies in the process, is very different from those that focus on long careers of walking in the park.
I don’t play golf but I like any one that want to change the norm and seems Bryson is willing to try something new.
Makes me think of the ts2 driver and its minimal use of bulge in a forgiving driver🤷♂️
Class is in session!
I wonder if that actually makes the golf club harder to work the ball left to right right to left?
bulge and roll was on infomercial irons years ago.
The good old Controller driving iron.
My friend help Bryson build his iron set, cool story behind those irons.
I would love to hear that story.
According to TPI research, a 1/2” off-center strike horizontally will cause a +/- 2.6 degree effect on start direction, which may result in Gear Effect depending on the 3:1 Face-to-Path relationship determining curvature. For ball speed lesser than 150mph (ie. club golfers), unless the off-center strike point is more than 1/2”, and the Face-to-Path delta is larger than 3 degree, the compensation from Gear Effect may not be noticeable even for a Driver with Bulge and Roll. For any iron, given that off-center strikes are usually lesser than 1/2” toe or heel, coupled with CG being close to the Face, Gear Effect is probably non-existent even for lower lofted clubs with lofts >15 degree.
In the future you guys could have a 3D printer in the studio and print out golf clubs 😂
So, increased energy delivered to the ball due to faster swing speed results in a more pronounced gear effect, because there's more deflection on off-center strikes? The added roll works to move the start line further from center to compensate for the increased gear effect?
👏🏼👏🏼, you aced the test!!
Bryson has invented a new type of club…
Something between Irons and Hybrids…
Hyrons!
Thirty years ago, when golf transitioned away from persimmon, the trade off was diminished gear effect. It used to be a common part of golf.
Can you do a test on same length irons
There isn't much to say that others haven't already
You lose some distance at the top end of the bag due to shorter leavers which can be offset by slightly stronger lofts. You are more likely to hit the centre of the face due to the slightly shorter shaft
You can gain distance in the higher lofts due to the same thing, such is a reason why Bryson has so many wedges. Inverse to the longer irons, you may find that you can't find the centre as much due to the added shaft length but that is offset by you not swinging the short irons as hard every time.
I have a set, been playing them since covid and absolutely love them
@@ForzaOwnz what length are you using for all your irons
@@hypent500 37.5"
My understanding is that the gear spin is created due to the horizontal difference from the CG of the club. It is not to do with the head moving in one way and the ball moving another. I know the PGA teach it this way but I believe this is incorrect.
On impact the ball wants to move towards the CG. When you strike the ball out on the toe, the ball wants to move towards the centered CG. Thats what creates the spin axis tilt. On a center strike, the ball is horizontally aligned so no spin axis tilt is imparted. By the same token, the CG position relative to the face impacts the back spin. Think low spin drivers like the SLDR. The CG was very farforward and low. The ball gets struck and is pulled towards the low CG, countering a little the loft creating backspin. (note CG of the head also impact the shaft so there is more at play interms of backswpin) The distance the CG is from the face also makes a difference. The bigger the distance the more the effect.
The reason irons don't need to counter this is that the CG is always very close to the face and that the ball can never get that far away for the center. In both cases the effect is so minimal.
I totally agree that as speed increases the effect on the spin axis tilt, and that for the majority of people there is absolutely no point in having bulge and roll.
Its not deflection that causes the gear effect its CG placement and reaction forces caused by the moment arm. This is why you want the CG lower than the strike point to create backspin and not topspin ... its just the same thing in the left/right axis vs top/bottom
The bulge/roll compensates for the gear effect spin, by starting the ball off to the right or left, bringing the ball back to center line with a draw or fade.
What amount of roll & bulge (inch radius) does Bryson have on this set of Irons?
Yeeesss! Go deeper, you have the audience for this. Even if you make more in depth videos a side channel. Love nitty gritty details.
would yall ever do this same review but with toe and heel strikes that are more dramatic and lower swing speed like the average golfer? I see your impacts and most of those are all places id be ok with hitting.
in theory, i think this test is absolutely right. However, at least for me personally, if i were to hit the heel with an iron my face tend to be more open, vice versa with toe strike. Reason being that i want solid contact. My ball tends to fade when i miss it out of the heel, and it doesnt have a leftward starting line due to the face that there isnt curvature on iron's clubface. I'd love to test out irons that does have face curvature to test the theory myself.
great review of the clubs. Love the mad scientist and all his ideas about how to make clubs better. Cant wait to see his clubs get released eventually and fingers crossed as always that they come out for lefties
8:19 I love the weeds! Do an episode where the weeds are over your head!
Did Wilson explore this concept in the 1980's with their model 1200 ge irons? They had an entire line of gear effect clubs introduced at the time. Those irons were the first set I ever played. However, as a new golfer then I couldn't feel any potential difference in those irons versus other conventional brand models.
All tech aside, they are a nice looking set of clubs.
Maybe have Bryson in and hire a iron Byron to mimic his swing to test his assertion
As D. P. Gumby would say 'my brain hurts' 😂
Bryson us single handedly why I hit as well as I do. I'll hit 330, 340 easy on the course 2, maybe 3 times, in the fairway. I have been playing 4 years. Golf needs his approach, and his tenacious propensity towards innovation.
There are lots of things you can learn and use from Bryson’s game. But, his clubs are unlikely what you want to replicate unless you have a ton of speed like him.
Sort of agree however, till a set of irons with either a positive or negative bulge is available, you never know. Interesting to learn more.
@@MussbacherIndustries they did exist back in the day. They were called Controller irons. That said, I'm all for experimentation.
So why has my 5-hybrid got a wee bulge but my 4-blade is flat? As a gentle low-80s dobber, would I be better off with a flat-faced driver?? Maybe some brave manufacturer (Adams??) might start to tune clubs more for Mr Average!
it would be interesting to see what different iron tech brings to this discussion. For example, I'd expect most (all) classic blades to act as you've demonstrated. Cavity backs are likely to have more variance, but not enough to warrant the complication. What about the foam-filled game improvement irons played by a person with poor head control and decent swing speed? Food for thought...
Would a better example have been hybrids? Do they have roll and bulge? Has Bryson gone full bag of hybrids that look like irons?
I'm sure @brysondechambeau would be happy to be on the show to explain his theory, considering you have filmed with Piage.
Are you gonna have a golf physics 400 course at UoT soon? This is way past math 100 LOL
Seems like the same idea behind the eleven golf hybrid irons set.
