WHAT IS SWINGWEIGHT? HOW DOES IT EFFECT YOUR TENNIS SWING? 

I like how the UPS deliverer is a reoccurring character on the show. Give Elliott more camera time next time. Would love to know more about him.

Very Informative and helpful thank you Tennis spin..

thank you for your videos, I really like your philosophy, and of course all your technical advice which I find very relevant.

At 16:00 I get what you're saying about short-court. I find mini-tennis warm up (groundstrokes in the service box) difficult to do with higher swing-weight racquets, but those racquets are then great at hitting through the court from the baseline.

Weight on 9 and 3 swing - spin and trajectory height. On 12- power and rebound height reduction.

You hit the nail on the head here 17.00 ....... Rackets are the weight they are because most players are normal people looking for some fitness, activity and fun etc. Those more serious about it can customise it for their own liking etc

Swing weight is literally a measure of how difficult it is to rotate the racket around the end of the grip. That's it. The number is proportional to weight times the distance from the end of the grip square. 10 grams in the butt won't change swing weight hardly at all since distance is basically zero.

Very interesting. I have a racket with 325 SW, but it feels like it has a heavier swing weight. I think I now understand why... It has overall weight that is centered just below the throat and above the grip.

Thanks for the content, Harry! Can you also talk about the twist weight of requests? Greetings from Amsterdam!

Thanks Harry!

I moved to a higher swing weight and I noticed it right away on the court. I’m hitting much flatter than before. I love hitting with tons spin. It would be nice though to hit with topping AND have it be heavy/penetrating . So would I have to just swing faster with the head heavy racquet to do so? I don’t play too frequently we’re it would hurt me anyways. Ironically because I was hitting flat, I ended up decreasing my swing speed which made the ball even flatter 😂 I have not tried to increase my swing speed thinking that would make the ball even flatter

Hey Harry! You said that you dont take measurements till after you find what you like feelwise. Do you match them all before that?

Maybe you’ve covered the swingweight chart and machine in a previous video? Interesting topic.

Good vid. My swing weight is 469. Definitely a flatter trajectory.

Thanks

To general info in video. its more complicated than that. Rule of Thumb: Higher swingweight = better player. Though...... beginner rackets has head heavy balance as they are light weight over all and they reduce the mostly the weight where there is no ball impact to not take away to much stability and so there is still power from racket. Thsi means you can buy a racket that weighs 270 with 300 swingweight (SW) With Intermidiate players you have more even balanced at 34 cm strung/33 cm unstrung racket and the racket will weigh 285-300 gram and may also 300-310 swingweight. With very advanced players you typically have a racket weighing 320 grams. Now the balance is typically only 31 cm unstrung-32 cm strung, such the swingweight is not getting redicoulus by having headlight balance. Whether you want to hit flat or with spin then is all in the technique and level of you.

Hi, I was curious, I work with college athletes and I wanted to know what balance, swingweight, and static weight scale machines you recommend for customizing rackets? Thank you so much!

You’re awesome

GOSEN IS FANTASTIC I USE G TOUR 3 1.18 AND IS THE BEST

If you know the weight (strung) and the balance, can you calculate the swing weight (without measuring). If not, what are the additional factors that go into swing weight (besides balance and weight)?

I understand customisation, but when a racket is so heavily customise doesn't it just indicate that the racket is wrong for you? Customising a racket is normal, but when every spare space has weight added to it, it's basically a different racket. It confuses me as to why one doesn't get racket closer to the weight preferred, that also has the touch you're looking for.

almost beefed up Fed specs in the Frankenstein.

Do you think your spasmodic, chronic late-hit forehand might be (partly) down to using far too heavy a racquet than you should? It looks like you’re not able to get to contact in time in most of your forehands. You can’t even get the timing right with a stock racquet as it is. Fix your technique than fixate about lead. Ask one of your many coach buddies to help you.

I wonder why don’t you use a heavier racquet from stock weight in stead of adding that ridiculous amount of weight? To me that means that’s not the racquet for you from the get go. I understand something like that on someone that is broke and has only one racquet. In that case is cheaper to spend 10’bucks on lead tape and make it work

Harry can we go back and talk about tension. If a 90 sq better at 45-50. 97 sq better at 55-60. 100 sq better at 60-65. 107 sq better at 65-70. So on so on. I'm just calculating at the racket level. I know people can have their own preference tension. Let's just say you have the best high racket tech and the best high level string. Would those tension best prefer.

You started to notice swingweight once you have two of the same racquet

Swingweight is a dynamic parameter, which can be defined as the moment of inertia I, also known as the rotational inertia. Rotational inertia of a rigid body (racket) is used to determine how much torque is needed to achieve the desired angular acceleration about the rotational axis. Let’s take a look at the axes of the racket again. The moment of inertia of a rigid composite system is the sum of the moments of inertia of its component subsystems that are at the distance r from the same axis. Now we can write down the general equation for the moment of inertia. Ip=∭ρ(x,y,z)⋅||r||2dxdydz (1) There are 2 parts of the equation. The first is the integration of the density over the whole volume of the racket, which represents mass, and the second part is the radius or distance r of the mass particle from the rotational axis. For the purpose of racket modification, we don’t need the equation in this form, and we can write down a discretized form. Ipy=∑ni=1(mi(ri,y)2) (2) Now we get the expression for the moment of inertia I around the axis Y, as the sum of moments of inertia of all the mass components. In practice, those mass components can be strips of lead, vibration dampener, strings etc. that are at distance r from the Y-axis. But in tennis, we use swingweight, which is just a moment of inertia about the parallel axis to the Y-axis, as shown in the picture below. We can see that the parallel axis is 10 cm from the axis Y. This is just the industry standard or I should say an arrangement. The axis is set at a distance of 10 cm because of the way we hold the racket, and the pivot point of the racket is not about Y-axis. Of course, this depends on the grip style we use, how big are our hands etc., but we need some common grounds to characterize rackets. If you know the moment of inertia about any given axis, you can calculate it about any other parallel axis. The final expression for swingweight is as follows. SW=∑ni=1(mi(xB,i−10cm)2)

Harry can you reconcile the specs you like to play with (Frankenstein) with your video about the hardest racquets to play with (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Aw5S1QPxBnE.html)? I agree with you in that vid that most of us aren't Roger/Joker etc. and shouldn't be playing with heavy racquets, you seemed to include yourself in the non-Roger group. But here your Frankenstein weighs a ton and swings "like a wrecking ball". Are you back in the ATP camp?

I always thought that weight added to the grip didn't add swingweight. Especially when it's added before the pivot point of the SW machine.

Isn't swingweight simply a result of the weight and the balance?

No comments?

348g swing weight, Harry are you mad? I’m surprised that you’re shoulder or or elbow doesn’t kill after playing with that kind of swing weight. I have two VCore Pro 97D, with a 5g variance and I can feel the difference, favouring the lighter swing weighted stick. You’re right, I do get more spin but, lack a little plow compared to the heavier version.

Head also makes a 10 gram buttcap. You can order them from Tennis Warehouse

Swingweigh we know🤣🤣🤣what about twistweight ?

346g is just too heavy.

Harry, you do not customize pro player racquets. Your method is so unbelievably unscientific. Stop lying and fooling yourself as well. Roman Prokes is getting a laugh outta you right now.

Someone please teach poor Harry how to hit a proper forehand and backhand.
