Physicist here, and I've been surprised this hasn't been done for years so I'm glad they finally caught up. Anyway, whilst it might make the bat feel lighter the physics doesn't make the bat swing faster - it's just tricking your brain into thinking that. You've just got the same bat plus extra inboard weight; nothing there increases speed. So that part is a myth. However what it DOES do is shift the sweet spot of the bat slightly further outboard which will create more bat speed where the ball is being hit. On top of that it also reduces the energy transfer back into the bat slightly and so more energy is transferred towards the ball. There's a lot of scientific papers written on this subject in the form of swords and pommels - the physics here is identical. I'd also imagine the hits to be slightly better when not on the sweet spot and to hurt your hands slightly less though I've not read that point in any papers. It's purely an assumption from how the physics plays out. What's more, none of this will show up in testing. They test the coefficient of restitution of the bat - the speed of a ball coming in and going out of a bat locked in place being shot at with a pitching machine. This only shows up when the bat is held at the base and being swung at a ball like a batter. So it's just pure benefit, the only real disadvantage is in the mass of wood potentially getting in the way of the batter's wrist or being annoying.
@@mrob8982 It makes a lot of sense that they didn't try it again for a while then. The physics are so unbelievably clear so it was baffling that it wasn't a thing, but for sure if it failed already they're going to be very reluctant.
The evolution of wood bats is interesting, since at the beginning of the sport, the bats didn't have a lot of taper going down to the handle. The handles were very thick, so there was quite a bit of weight at the hands. Then the handles started to become thinner and thinner into the current modern era. Now, with these puck bats, it's like more weight is being placed near the hands again, but distributed below the hands rather than in the handle. Curious to see if this trend gathers any momentum.
Hard to say if the velo difference is because of the extra weight or shape, could just be a better piece of wood with tighter grain where it matters. Would need to test a larger sample size to really figure it out, but what you're seeing does make sense.
The puck knob is always gonna result in a lower MOI/swing weight and a slightly less-dense wood. So it makes sense that velos would be down a little bit.
I have a Goods that I received from a teammate of mine. He wrapped the bat somewhat similar to how you would see a puck knob and it’s got a massive flare/knob at the end so you don’t really Grip it at the end, rather you just choke up about an inch on it or whatever you feel comfortable having your bottom hand at and it acts something similar to the puck knob. There’s so much material towards the handle that it moves the weights from the “D” to about an inch or two above the connector piece. Ultimately making it a balanced goods.
Former Pro golfer here. Just noticing that Will is gripping the bat pretty far into the knob. It might feel better (guessing that’s why you’re doing it) but the more you grip into the knob the less effect of the counterbalance. Probably why you’re only feeling a slight effect difference compared to JT. If you look at the MLB guys and where they are gripping it, you’ll notice there is almost space between their lowest hand and the knob. So moral of this story is if you want the counterbalance to work then you have to use it correctly. Cheers. By the way if you ever come back out to Kansas let me know. I’d be curious if a Pro golfer that hasn’t played baseball since the 90’s could hit one out. No practice before of course.
i wonder if it makes a difference where you hold it with the puck knob. I feel like some of the guys swinging it almost choke up a tad with the puck knob as opposed to holding it further down similar to having your pinky slightly off the end of a regular taper.
Been waiting for this. I've got a weird spinal problem, front shoulder is literally higher than the other. Makes barrel dip an annoying problem for me since my shoulders are literally not level to start with.
I just bought the AP5 puck knob today. I wanted to try it out and see if it makes a difference in my swing. From a person who hasn't swung a bat in 5 plus years, I did notice a difference from the puck knob vs standard knob. I felt the puck knob does help with your swing. Also, going back to the regular AP5 standard knob i really noticed my bat speed. I'm going to keep swinging both and see how I feel about. Would love for you guys to do a follow-up video to see how you really feel about it.
Interesting, I’ve been following you guys from the UK for years and this idea of a counterweight on the end of the handle has been around in cricket for a while. Personally I like it on a bat, especially when using a heavier bat for shorter forms of the game..
Would love to see you add a Blast Motion sensor to your videos to see some of those data points. JT's hand speed looks impressive to me. Would have been cool to have that when you started this channel and compare it to present day.
I am no physicist or bat engineer but i am a tennis pro and have been customizing racquets for quite some time. We have been adding weight to the handles for years to make the racquet more whippy but with over all the same if not a little more static weight. There is a unit of measurement in tennis racquets called swingweight though and its kind of the big tell on how heavy a racquet is actually gonna be while swinging. It also can indicate how much power a racquet will have sometimes. More weight normally means more boom. We calculate manually via a a math problem or with a machine. I would imagine bats and the development of them could use a unit of measurement like this. I have always wondered why bat development never went that direction.
Really appreciate your comment! I am a huge golf fanatic and I'm actually researching things for fitting myself with equipment. The same concept absolutely applies in golf clubs. Most manufacturers make the clubs loaded on the end which doesn't fit a lot of people that's the standard. I believe that most people can't handle the weight of the club especially when they first start playing and I believe a lot of their swing flaws come from the equipment they're using. Would you think that's fair. So for example if a child started with a racket that the swing weight was too heavy the child's going to make a lot of compensations in their swing because of that? So then when an instructor looked at them they would notice all these flaws in their technique when in reality the flaws are because of their equipment? I'm starting to believe that most amateurs should basically get fitted first to figure out a balance point in their clubs and their own body preferences the way they would want to swing the club. The way I'm singing now is you could swing it like a sledgehammer with the weight on the end like normal, or if you took the weight off completely and just swung the stick, or if you turned it upside down and had the weight below your hands. You have those options and everything in between for the balance point of that piece of equipment. I would feel like a racket would probably be about the same thing right
If you want a pick knob and don’t care to much about how it looks then go to American bat smith they have a really large selection of models with almost any knob you want
Would love to see you guys give Cash Cow bats a swing. They make puck, no knob, flare knob etc. and are priced super well. One guy makes them and he does some cool stuff with the cupping on the ends of the bats to get weight off them.
wish they made puck knobs when I was playing. if you add some metal washers to the knob it works even better, the wood is too light still. It allows the bat's balance point to get closer to the handle node. you must choke up a little so your bottom hand doesn't touch the knob.
I think id really depends on that kind of swing you put on it. it will definitely help with hitters that have more twist in the wrist. Will uses his rear elbow to turn the barrel and snaps forward with the wrist. There is a lot less twist. So it I think it comes down to the approach, angles, and weather you are twisting the wrist to contact.
I need you to test out a Liquid Metal Plasma it was an underrated juiced to the gills bat from the BESR era but i feel like you are the guy who could find one
Definitely need an overly balanced drop 0 vs overly endloaded drop 3 wood bat comparison. American Batsmith S44 -0 vs American Batsmith TS28 -3, for example
The Dovetiail 243 PUCK Knob is one of my go to’s for my left handed side (Switch Hitter here) got most of my teammates on it and they absolutely rake with it along with a Mizuno VKong we have. I’m curious as to how the PUCK ProXR knob could be from Dovetail Bats as well
@@Guzberry- not necessarily. As a skinny 5’5 dude I can swing most BBCOR’s with ease. Some wood bats with larger barrels and weight usually merits a puck knob
@baseballbatbros I just got the select pwr and im launching the ball but it makes a high pitched sound, how do i make it sound cool like a gun shot just like in your videos?
If anyone paid attention to Barry Bonds' bat you'd know this isn't such a new concept. Massive knob that he gripped above for better barrel control and bat speed.
How u grip a bat could also affect how well the puck knob works for u. If ur a guy who holds it really low on the handle or even slightly over the knob like Will it won’t work as well for u as someone who holds it normally or even choked up. To sum up what I’m saying: the higher up on the handle u hold, the stronger the effect, the lower, the less the effect
video idea: best bats for high schoolers, so like your usssa composite matchups but with bbcor bats for high schooler, also would love to see select pwr vs icon!
So if I’m custom ordering one and I want a 33.5” do I need to order a 34.5” or do they take that into consideration and a 33.5” doesn’t include the puck?
If you were to choose any usssa bat that cost a maximum of $300 which would you choose I am a 12 year old and weigh 175 I’m leaning towards getting a cat x one piece, Zoa, and the Easton hype comp all drop 5 32 inches
You guys misunderstood the sizing. You should have tested the same size to get a comparison on everything. But yes I'm a way it's to help you swing a bigger bat with the same swing speed. But if you were to test both 33/30 then you'll see a massive difference
I got a question.... has anyone else ever got a Demarini 2 piece bat delivered, and when you received it, the bat is crooked? The handle and the barrel are definitely off a little on my son's The Goods 2 piece bat. Driving me crazy.

Just so you know that this isn’t a new trend. It’s an old trend made new. The majority of bats from the 1880’s and early 1900’s had this design.
I’ve seen every team has a guy or 2 using puck knob
I could listen to that all day!! Just might be the best sound ever
Finally swinging wood bats again, praise the baseball gods
Thank you for explaining the puck knob. So much information when it comes to picking a baseball bat.

If the puck knob is more of a contact hitter's knob, is it better for contact hitter's than an axe handle?
@baseballbatbros would getting a -2 help with the density issue? And would it kind of offset the benefits of the puck?
I think so, yes
Yes and yes! 😂

See how much better your velo got after switching back to the regular bat even being tired and stuff? I think that means the luck bat did its job.
