Hey jemsiter- have you had a chance to spec these frames out yet?
I've been busy with projects and stuff. I will try to get the specs this week.
Maybe I will bring it to Racket Doctor and have them measure the specs and setup a stock frame with the exact same specs.
Anybody else thing, judging by yoke, just above the handle it could be a Wilson?
i didnt know he uses tourna grip i thought he was using the babolat grips
I might sound a bit dumb for asking this, but the swing weight that you put there, I have no idea how to read it. I see on tennis warehouse, for an example, that the Pure Drive Roddick GT has a swing weight of what they simply put just 334 grams. Now is the 322 kgxcm2 basically just say that its 322 grams swingweight or does it say something else? And also, if you added the strings, would the swing weight be added too proportionately like as in a unstrung weight of a racquet increases by 20 when adding a string so would the swing weight of that racquet would increase by 20 as well? Also, would the balance have any difference as well?
This is just a hunch, but I think the reason he's not featured is because you can't get his tournagrip from the stores and, unlike a paintjob, it's obvious. This might also be the reason he uses black finishing tape and not red, like most all the other tourna users have (same with Sharapova, maybe). Again, just an educated guess, maybe completely wrong, just throwing my (not so) regarded opinion around.
The kgxcm2 is the correct full term for SW so the numbers are comparable.
Roddick's unstrung SW is 322, the rule of thumb is to add 30 units to account for string so that takes you up to 352.
The balance would change as well to account for the strings.
Regarding the tourna, maybe he just likes Tourna and is not under contract. I would imagine that it's fairly expensive to sponsor A rod and it might be beyond the marketing budget of Tourna. The Bryan Brothers and Ryan Sweeting that are featured in the ads would likely be much less expensive to sponsor.
kgxcm2=Kilograms per Square Centimeter. It's a measurement of force.
As was later confirmed to be the case, it would be expected that he actually would have lead, even with a custom handle. Even with customized gear, lead is used to adjust for the differences between frames when they come off the line. If you make custom grips, etc. exactly to weight spec, it leaves no room for adjustment to the frame once assembled, and no two frames come of the line exactly matched. Instead, the equipment is made lighter than spec, and then weight, balance, SW, etc. are adjusted with lead so that all the frames match. (This is also why the pro stock frames discussed on these boards...e.g. Head PT57s...aren't particularly heavy to start with.)
As stated by another poster above, he's a bit out of their price range. Also, he has a full kit deal with Babolat, meaning that he, if only in name, endorses Babolat frames, strings, grips, bags, shoes, etc., even if he isn't always using them. That is also why he often uses generic black finishing tape rather than the distinctive red TournaGrip tape.
So I finally got time to measure the specs
Both sticks are 346 grams and 4 points headlight
I will post pics soon
I actually got to hold the racket today. It felt pretty light in my hand even though it was 346 on the RD gram scale. The OP also took pictures of the frame on the balance board/gram scale. Anyway, at least you didn't get the chance to talk nonsense in this thread.
So approx 20 gr of lead after overgrip rubber band and strings
I thought it said 346g on the post above?
That would be inline with the 320g unstrung specs.
Keep in mind that Roddick's actual frame is the old PD+, NOT the PDR+, so the unstrung weight is actually more like 300g.
Agreed, but I was going off the weighs posted on here by racquetcraft:
Roddicks unstrung specs
Weight: 320 g weight overall
Balance: 32.3 cm
Swing Weight: 322 kgxcm2
Thanks for the follow up. What do you plan to do with them? Any interest in selling one :?
I asked about the price, but he said he couldn't tell us!
Thats what I was saying you maybe misunderstood me:
~6-7g approx. overgrip
~20g lead give or take to correct for babolats qc
Weight: 346 grams
Balance: 4 points headlight
Both sticks are perfectly matched
The following are some pics of the Roddick frame and a retail pure drive roddick plus GT
There are some differences on the paint if you look closely
There is no specs printed on Roddicks, and the head guard is different
Roddick on the left, retail on the right
Did you adjust the balance board to compensate for the frame being longer than standard? I forgot to mention that while you were measuring the sticks.
Are they 27.5" long?
paintjob at 12 is slightly different
I've modified the retail pure drive roddick plus GT to match the specs of the Roddick frames. I'll see how it plays this weekend
I would guess Unique can't afford Roddick...how about this...maybe Arod is doing the BB a favor. Maybe BB get a royalty based on number of grips sold. I try to figure out why certain guys do certain things. I mean Roddick has huge deals already and maybe he is just doing a favor here. Blake is sponsored by tg too right?
I plan to keep them. I might considering selling one if someone offer me a good price
Good question... If the OP didn't adjust the board...
This would make them about 6 pts. HL rather than 4 pts.
How did you come to own them?
I did not adjust the board. I asked the guy at racket doctor to measure the retail pure drive roddick plus for me before I measured the Roddick frames. Not sure if he adjusted it...
I might have to go back later and measure them again.
jemister, could you please say around how much lead and where you put it to much the Roddick spec. Thanks
Retail Pure Drive Roddick Plus GT (picked from a few to get the lightest one)
Strung with PHT 17 main and NXT cross @ 60 lbs.
Tourna II grip and rubber band.
One layer of 1/4 inch lead tape at 3 and 9 on each side (total of 4)
It is not exact but very close to Roddick's specs. Weight about the same (within a few grams) and same balance.
thanks and did you have to add any to the handle?
no I did not add any lead to the handle
Thanks for the specs!
But also, do you know the swing weight of the racquet?
Ahhh, so. My misunderstanding. I thought your were referring to the stock weights. I can't speak for RacquetCraft without talking to him first, but I assume that the unstrung spec he posted was post-customization, as he would have been referring to a ready to use frame. Those numbers make complete sense in that context, so it sounds like we're all saying the same thing. A base PD+ with about 20g of lead added would weight in at 320g or so naked. Add the strings, overgrip, rubber band, etc. and 346 sounds just about right.
is it just me or is the pjed pd looking lighter blue at the throat than the retail version?
Let us know how the rackets feel differs after hitting with them, i want to noe the difference in the how stiff it feels with or without the cortex
You could also just find a Pure Drive team + racquet on the auction site and throw some lead on it and you've have the excact same racquet Roddick uses.
it just seems like they have 1/2 length lead tape and how long is a strip of the 1/4?
yes the roddick frames are lighter blue than the retail
Turns out the balance board was not adjusted last time I measured the sticks. so...
Correction for Roddick's specs:
6 points headlight
One more thing... the retail stick I got is 344 grams and 7 points headlight after the lead tapes, overgrip, and rubber band. The rubber band I use is slightly shorter than Roddick's. So that might be the difference? I am thinking I should add 2 grams of lead to the head and that should nail the specs. But I think anyone could get a retail stick, add the lead tapes, overgrip, rubber band, and that should be close enough.
You have to hit with both frames strung with identical strings to get the most out of play-testing them.
Would love to hear more re the feel of Andy's frame/s...
Is he another pro who actually has a far lower stiffness RA and softer feel (like Djoker and Del Po are rumoured to have) than ppl would imagine?
Why is everyone so interested in matching Roddick's specs for the GT+? It is common knowledge that Andy does not use this stick, but an earlier PD (I belive the one with the swirly PJ).
In other words, a retail GT+ matched to these specs will NOT play anything like Andy's actual stick...
I do not plan to hit with those frames. I want to keep them the way they are. The last person to hit with them was Andy
To me, weight and balance makes more different than other factors. The retail matched to the specs will not play identical to Andy's sticks, but close enough for most of us.
Andy's stick is very stiff. When I hit it against my hand it feels stiff. Also it has slightly more vibration than the retail. The cortex dampens it a little
thanks for this jemsiter. nice to know the balance for his stick. i was reading through the rafa and fed threads and i dont think we ever found out the balance of those sticks...
