Federer credits the move to a larger frame for "serving his best ever"

So I just watch the Federer USO post match interview where he said the "bigger head size has given me easy power".

He also stated that this was the best he has ever served. Powerful words from the GOAT that will most likely shatter TT's most hardheaded poster's insistence that he should have stuck with the 90. The Eagle himself said the move was a good one for him and it was all captured on HD Video for the world to see.

Actually that's not quite what he said -- but pretty close. He said he is serving maybe as good as he has and maybe even a better percentage of firsts and more consistent than in a long time. And he says now after about a year and half he is really used to the new larger frame.

Federer can think whatever he wants, but the stats show that he used to serve better with the 90.
Read up on correlation, BP.

Nadal used to win slams before they made him put that Lunarballistec PJ on his 4.3's. That has to be it. He should find his old pairs, stock, and get some more slams under his belt. Stats show it.

You're right. There's no correlation between how Federer is playing and his racquet. As we all know, it's not about the racquet.

You got the first part right. But there is most likely a correlation between his racket and his results, just as there is one between Nadals triumphs as RG and the PJ on his shoes. But correlation is not the same as causality.

Federer won 17 slams with a 90 square inch. Sampras won 14 with an 85 square inch. Bjorn Borg won 11 with a 60+ square inch.

So that means Federer will win 20 slams with the 97 square inch! :D

I think much of his recent success is due to his improved play with Edberg in the mix. However, being a RF97 user myself since it came out last year, can't hide the fact that it's a fantastic stick!

It has begun.... Another 20 page rant of bp saying Federer was better with a 90

It doesn't mean anything that his legs are not the same as they were 10 years ago, neither is his back, or any of his body really.

The switch has added life to him and he's playing to his highest level possible in his current physical state.

He can't move like novak or murray, but he can make up for a bit of it by using a racquet with a bigger sweet spot.

If he runs slower than novak and Andy and the difference in court positioning after hitting 2 shots is 2 inches, then that means by the third shot he is 2 inches further than he would be ideally. With a 90 that would make a huge difference, with a 97 it isn't as drastic.

Now this is an example, obviously he is not that out of shape compared to Andy and novak, but over the course of a long match he would start shanking a lot with the 90 which just proves his slowing. Now with the 97 he plays better than he would in his current state with the 90.

His game is very refined, he doesn't rely on flat out power but a lot of point construction. The 97 is a good balance, a 100 might be a bit odd

I think most professional athlete's brag about the new equipment because that's what there sponsors would want them to say. Weather its tennis, golfers, racing, etc. the equipment manufactures are hoping there paid athlete's help promote there new products. Weather it's true or not, or they just sugar coating the product, that's for the consumer to find out.

Are you not going to quote my post knowing full well I'm right?

Federer is 34

At 34 he would not play his best tennis with a 90 on top of already not being able to play his best tennis ever because his best was when he was 26

His prime was in 2006. And it's 9 years later, we cannot expect him to play this level 9 years later

Are you saying there's a correlation between a player's age and his racquet?

Because there isn't. Players from 8 to 80 all used to use the same wood racquet. There's no reason you can't play your best tennis with any racquet at any age. There's no correlation between age and size of racquet. Krickstein is almost 50 and he uses a PS 6.0 85. Meanwhile, little kids are using Oversize racquets.
 
He is playing better than ever. That racket does a little but with heat and the roof, indoors condition suit him. Tennis pure. His toss isnt blown away and Then he is the best.. sorry Nole.

1. Because this topic comes up so frequently, I decided to look into the available data, and looked into Fed's serving stats through out his entire career back in March 2015. Unless I've missed something very recently, he's still serving about the same as he always has, at least in terms of Average 1st serve speed, Average 2nd serve speed, and 1st serve percentage.

2. I know there's lots of things that stats don't quite cover, and "serving his best ever" is a slightly nebulous statement, but wondering did some aspect of Fed's serving, pop off the charts in last few months?

3. Regarding the whole "Fed is getting older" thing:
I agree. Roger's fastest recorded serve speeds were 132 and 143 MPH, both recorded back in 2010, with the 90 inch frame. From 2011 on, his top serving speed has consistently been in a narrow range of 126-129 mph. However, there is a way to argumentatively rule in or out the age factor. Just shrink the time frame of examination. Roger first dabbled with the larger head in July of 2013. Then declared he'd stick with the larger head full time in Dec 2013. If you compare serving stats from mid 2013 to early 2014 (Fed is just a few months older and with a new stick) all the widely available serving statistics (Average 1st serve speed, Average 2nd serve speed, and 1st serve percentage) you will see these numbers are very similar.

4. Just to re-iterate: There are many aspects to effective serving that are difficult to quantify and measure. Not quibbling with Fed's opinion of his "best ever" serving game. But when you see that average 1st serve speed, average second serve speed, and 1st serve percentage are pretty consistent from 2011 on, makes me wonder what he thinks has improved. Maybe it is placement, accuracy, confidence under pressure, spin etc ... but as to the "easy power" thing, I don't see any evidence of that.

Well a switch from a 90 to 97 isn't as big as to a 100.

It's almost a 10% increase

it would be slightly less maneuverable

The 97 stays closer to what he likes, a 100 would just be strange

Little kid junior racquets are actually sub 93 inch heads so that they are proportionate

So oversize... False

The easy power might be fed using less effort

I think we should look at his data when he switched and look at the consistency of his serve over a match.

Maybe there we will see something that makes his statement more true.

Find his stats months apart and look at them more closely rather than a summary, because maybe he's able to serve out matches easier than before

Maneuverability has everything to do with twistweight and weight distribution. As twistweight is determined not just by the weight on the sides of the frame, but the frame width it's self.

I'm willing to bet they picked 97 because it's more marketable. It's basically a bigger version of a prestige with box beam and high static weight, and pws bumps.


People on here make far too much out of the headsize. Headsize is important when speaking about the string pattern and consequent string density/how open the bed is. Especially when it comes to power. Stiffness and layup simply determines feel, while weight distribution and stringbed determine power, and weight dist determines manuverability and stability

Awesome sauce. I don't have the time to investigate any further, but I'm happy to give you a head start and share what I found when I looked into Fed's serving stats back in march of 2015. You'll notice the digits which are collected (at matchstat.com) will vary from tournament to tournament, with the majors being the most comprehensive.

Just to re-iterate: There are many aspects to effective serving that are difficult to quantify and measure. Not quibbling with Fed's opinion of his "best ever" serving game, I'll assume he's got a good grasp on the subject. But when you see that his fastest serve, average 1st serve speed, average second serve speed, and 1st serve percentage are pretty consistent from 2011 on, makes me wonder what he thinks has improved, or what has improved since March 2015.

Racquet Switch, July - Dec 2013

2013 - December " On the same day he announced he’d be taking it old school by hiring Stefan Edberg to join his coaching team, Roger Federer revealed he’ll also be starting 2014 with a bit of the new. As noted by Christopher Clarey of The New York Times, Federer recently confirmed he’ll play with a larger, 98-inch racket head in Australia. The 17-time Grand Slam champion used a 90-inch racket to win each of his majors. Last summer, he briefly dabbled with a 98-inch model before going back to his regular racket prior to the North American hard court season. He explained his decision to the Swiss-German daily Basler Zeitung. (Note: The quotes have been translated.) I’m going to play in Australia with a similar model as in my first attempt. Actually, I wanted to switch back after the U.S. Open again, but then I had so much to do with myself and my game, that I kept it on hold. Now, I had more time to make more small changes and together with my supplier company Wilson worked on the fine details of the racket. […] But now I have the feeling that this is the right time for a change in the racket. I’ve played through two and a half weeks with the new model and am confident. The racket is very good in the hand. But the truth will come out on the court. We’ll see how it affects me in the tournaments in Australia."
--USA Today
http://ftw.usatoday.com/2013/12/roger-federer-racket-98-inch

2013 - July 23 "Roger Federer will continue to test out a new racket at the Swiss Open in Gstaad this week before deciding whether or not to stick with it for the build-up to the US Open. Federer debuted the blacked-out Wilson racket - which has a larger, 98-square-inch head - in Hamburg last week, his first tournament since his shock second-round exit at Wimbledon."

Wait, where does it say federer has hit 143mph? EDIT: Above post. Wow that's a freak number lol. He reaches up to the uper 120's as I thought, but very rarely above that.

He rarely reaches into the 130's. His average 1st serve must be around 117-121 for most of his career. The occasional 127 and every once in a while 131.

The new racquet gives more margin for error by having a bigger contact area..


I think saying bigger frame=more power is misleading. He has a more open stringbed now and longer strings, both of which require a higher tension, where as his last frame had a very low tension. It's hard to make a direct comparison when we really don't know what his 97 specs out for twist weight, swing weight, balance or even static officially. Compared to his 90 we found out more and more over the years.

But ESPN or some broadcaster did a speed comparison between 2014 and previous years for fed's backhand (not just 2013). And his mph went up by like 3-5 on average. That's a pretty serious bump for someone of his caliber.

A more accurate comparison would be to evaluate his stats for a period of time before adoting the new frame equal to the period he has been using it.

That way you'd be more accurately comparing "Fed's Current Body with 90" Frame" vs "Fed's Current Body with 97" Frame".

By looking at his entire career for comparison one is comparing his body at the height of its power to its inevitable decline with age and, more importantly, the wear and tear those many years place on the body.

In other words by comparing his entire pre-switch career to post-switch career you're changing THREE variables: effect of age on body, effect of wear and tear on tour on body, and effect of racquet. That's useless if you're trying to isolate the effects of the frame.

It's also why it's safe to ignore BP on this topic. Federer is naturally doing what I suggest: he's judging his performance for a smaller period of time pre-switch to post-switch. And from there he's judging his POTENTIAL performance using the two frames.

Acheiving given stat is one thing. The level of comfort and confidence while achieving the stat is something else and can be known only by the player (i.e. a player might be able to hit the same serve quality using two different frames but one feels difficult and the other feels easier).

1. Because this topic comes up so frequently, I decided to look into the available data, and looked into Fed's serving stats through out his entire career back in March 2015.

4. Just to re-iterate: There are many aspects to effective serving that are difficult to quantify and measure. Not quibbling with Fed's opinion of his "best ever" serving game. But when you see that average 1st serve speed, average second serve speed, and 1st serve percentage are pretty consistent from 2011 on, makes me wonder what he thinks has improved. Maybe it is placement, accuracy, confidence under pressure, spin etc ... but as to the "easy power" thing, I don't see any evidence of that.

Don't have a dog in this fight. Just telling you what I see. If you see something I've missed, feel free to point out. Source provided below.

It's also why it's safe to ignore BP on this topic. Federer is naturally doing what I suggest: he's judging his performance for a smaller period of time pre-switch to post-switch. And from there he's judging his POTENTIAL performance using the two frames.
I mentioned nothing about his age nor anything else. I only mentioned the stats, which are the only facts that we have to go on. In fact, I don't believe Federer qualified his statement by saying - "I'm serving better with the new racquet for my age." BTW, age certainly hasn't hurt Karlovic's serve. He's serving better than ever. And he's older than Federer at age 36.

Karlovic hasn't played 1000+ matches

He's also nearly 7 foot

So you think Karlovic just sits on his couch watching TV and eating ice cream when he's not playing matches? No, he's out on the practice court playing tennis and practicing his serve. And he has a to carry around a lot more weight than Federer does. And does height affect how you age? So your serve speed drops as you age, except if you're tall?

Are you mentally ill, karlovic can't move, but he can bomb 145 mph serves

He's played half the matches fed has and has not played as high quality matches

Federer isn't gifted with karlovics serve, he has to actually play points rather than coming to net after every serve
