    Talking about the R-7, not the RD-7.


    Going on the advertising material (found at the website, '80's tennis') it has a 95sq head size and weighs less than 12oz (between 325-340grams,depending on grip size). Does anyone know the other specs - swingweight, balance and flex ?

    Thanks.

    Hey Andrew

    Thinking of trying one? My r10 was the very first grahite frame I had, but I agonised over the R7 at the time.

    Can't help you with the weight, pretty sure it depended on grip size with this era of Yonex. Flex would have been mid 50's at a guess. The R7 felt a touch stiffer to me than the r22.

    I can just tell you a few things about the R-7 - they were definitely larger than 95 - (97 or 98 sq. inches), 18.5 mm box beam, 16x19 pattern. Not sure about the weight (most likely varied by grip size. I played with the R-7 from '85 - '89 as a scrawny kid and played 1/2 (nice square shape unlike current models). I remember my 1/2 being slightly headlight near even balance (my R-10s were definitely more headlight). I prefer the R-10.

    Thanks guys,

    As I mentioned, the advertising copy for the R-7 states that it is between 325 and 340 grams (so, under 12oz). Obviously that will depend on grip size.

    stevewcosta,

    I remember asking about this a while back and people were very sure that the R-7 was only 95sq. TW have the R-22 and R-23 at 90sq.

    galain,

    I'm hoping to pick one up cheaply. Have found that I play my best tennis with Yonex (a combination of the grip shape - seems to naturally push my forehand grip to semi western instead of a weak continental- and the head shape - seems to allow me to hit flat but retain excellent control and the slice is very biting) but they don't have much currently available that has good feel. Have been playing the RDS-001 MP and winning more than I lose (for a change) but really not enjoying the stiffness. Tried the RDX 500 MP but didn't enjoy that either (just felt like a 'nothing' kind of racquet - comfortable but doesn't really lend itself to any one style of game). Thought I'd give the R-7 a try until I can find something newer.

    I just measured mine unstrung:

    length: 26.75 in
    mass: 346g
    balance: 314mm from end of buttcap.

    This is a "Light" version. They also made "SL" version. I remember my R-10's used to be SL, and they felt lighter. Headsize is much bigger than 98. I would guess to be around 104 sq in.

    I have a couple and with overgrips, head tape and a rubber band dampeners, they weigh in around 12 ounces. Head light, bumperless frames.

    Head size in 90/95, has the oblong head so hard to say for sure. Not noticeably bigger than a R22 though and plays very similarly IMHO. I think the 22 is a little stiffer but not by much.

    Good frames for the money as they usually go pretty cheap.

    I have the R-7 somewhere, and I do recall that it was bigger than the R-22. I also have the R-18 (blue) which was smaller and more like the R-22.

    Was the R-7 the chocolate brown one? If so, I once taught at a tennis resort alongside a guy who used them. (Interestingly, he was a kleptomaniac and pathological liar, the first and by far worst that I ever met. Though a mediocre player as teaching pros go, he told a convincingly detailed story of getting a wild card into a minor tour event and getting exactly one game off Lendl. He was fired when a sizeable portion of the pro shop's inventory was found in locked suitcases in his room. I assume the R-7 had nothing to do with it – except perhaps being itself stolen – but racquets have made so many of us crazy that you never know, so I'm including this tale in the post.)

    If I'm remembering correctly that they were all contemporaries, I recall the R-7 and R-10 as being definitely longer than the R-22 and R-27 and at least as wide, roughly as rectangles are to squares. I believe the higher numbered of each pair was quite a bit stiffer, too.

    That was one of Yonex' sales slogans for the R7 : The Yonex R7, The Number One Choice of Kleptomaniac Pathogical Liars.

    Was the guy engaged to Morgan Fairchild? :) Yeah, that's the ticket.

    I have known a few pathological liars in my time. They lie about everything, even about things where there is no apparent motive for them to lie. Very strange and very sad.

    The 22 is relatively flexible and plays a lot like the 7 IMHO. Never hit with a 27. I would say the RD7 is bit stiffer than both the 7 and the 22 but that is a subjective judgment.

    I compared the 22 to the 7 last night.

    The R22 has a little smaller head size and has a longer throat opening. I would guess the R7 is about a 95 and the 22 is about a 90.

    Both are around 12 ounces strung. My 4 1/4 grip size R7's are around 12.8 ounces with two overgrips over the original grip, head tape and a rubber band damper. The 22 was 12.7 ounces with a single overgrip over the original grip, rubber band dampener and head tape. An overgrip adds about 6 grams as does head tape. (I have added roughly 1/2 to 3/4 ounce to the racket weight with the added stuff.)

    sorry to resurrect!

    As a frequent user of the R7, R22, R27, I can very firmly state that the R7 is from a different mold. Meaning it really is a slight bit bigger than the other frames mentioned above, all of which I believe to be 90sq inches. I personally love the R7, and after comparing to known frame sizes, it is slightly bigger than my SRD tour 95, but not by much. I'm truly saying this is a 97-98 in frame.

    If you get a chance to measure it, could you post the max length and max width of the inside of the frame? It wouldn't let us easily calculate the head size of an isometric Yonex the way we could an oval string bed, but it would give us at least an idea of how it compares to other rackets of known head size.

    R-7 vs a 95. R-7's string bed is much bigger.
