The Penta 99 Gold & Silver, have super thin beams (the leanest in tennis at 15/18/17 millimeters). Fortified by five solid-cores for super performance, comfort, durability & control, they are a boon for advanced players who supply their own power with long fast swings, & hard-swinging intermediates who need help tempering their rocket-launched shots to keep them in the court. The specs for the Penta 99 Gold & Silver are practically the same, except for the slight variations in their stationary & swing weights. The X-Dual Gold is for bigger & stronger hitters while the X-Dual Silver is tailored for smaller players  as well as seniors. The advantage of the thin beam is greater maneuverability & racquet-head speed that helps create severe spin because there is less aerodynamic drag during the swing than with wider frames. Thin beams also reduce shots that inadvertently bounce off the frame instead of the string bed, especially when the racquet face is closed & forms a “shadow effect” over the string bed. see full review below.




Amongst all the recent frames Donnay has made, the X series is absolutely the most characteristic of the brand. Not only because of the uniqueness of the frame, clearly inspired by the Pro One of the past, but also because the design and implementation of Donnay X is an experience that is not shared with any other company, especially the type of molds and type of racquet production. These frames at 15/18/17mm are the most slender of all racquets curently on the market. One is almost instantly reminded of the original Pro Staff 85, but in 99" inches. The names "Gold & Silver" have corresponding colors of their grommets & headguards. At the handle there is the usual Donnay Interchangeable Palltets System, the grip, the Donnay Cushion, is a well-made product, but really thin and sensitive, so that the handle feels & measures slightly smaller than the size indicated, however, with an overgrip we were dead on. One could also replace the original grip, thin at 1.4mm with a 1.90 / 2.0 mm, to solve the problem.The butt-cap has a transparent inset, which reveals the Xenecore material that fills the whole frame, in it's orange / red color. The appearance of the racket is very rich, brilliantly elegant, in fact distinguished.

From the baseline, we appreciated the vigor of the frame, robust in general & ready to give players a boost, without being a real gun. The improvement over the previous version is clearly noticeable.

The backspin is smooth, Soft and sensitive. It is guides the ball to the end and modulates at will, both in height & in intensity. The ball is literally bitten by the pattern, it remains there until the arm decides where to place the ball. With this feature, in addition to the side-spin available, tricks are always within arm's reach.

 At net it is easy and solid, strong at impact and you feel the ball very well. Service is complete and effective. Slice can be deadly, even on the serve. Excellent kicks, leaping high and deep, with interesting trajectories, even effective in defense.

Ultimately , Donnay made us wait a bit 'to get a suitable replacement for the X-Dual's , but it was worth it because X-Penta 99 is undoubtedly an improvement.
The new Penta 99's are classic frames, overflowing with spin potential. Fexible frames, communicative, full of feeling and control, which does generate a disarming amount of power when needed while being easy on the arm. Like we said, true "Classics"

Hexacore (6 Cores)

Hexacore-filled Xenecore racquets provide "feels soft/hits hard" results because of the addition of a fifth or sixth core over the previous quad, tri, dual and single core frames.With more cores on each side of the shaft, they provide even more comfort, power, stability, precision, accuracy and control.

Even though these racquets are flexible for control, they provide power without torquing at high velocities. The coefficient of restitution is extremely high which provides this unprecedented power. So the 200 pounds of force transmitted to your arm from hollow racquets is reduced by 70 percent with Hexacore.

The new Donnay-Xenecore Formula Hexacore and their lighter cousins, the Xenecore Formula Pentacore & Hexacore Lites, are a virtual extension of the arm with its astonishing paradoxical combination of big-league power and sublime comfort.The Formula Hexacore translates into pure power, but unlike conventional stiff frames such as the best-selling Babolats Pure Drive and AeroPro, it is easy on the arm.Play test results show it has the inherit big-league power and specifications of the best-selling Babolats but with a smooth, buttery feel, a larger sweet spot andbest-in-industry stability.

Herxacore Pro One 97 with its flex-rating of 59 provides pinpoint control and feel for 4.0 -and-up players. For the Head Prestige or Wilson Blade players with high-velocity full swings, it means no torquing and the ability to direct the ball where you want it to go.

How are Donnay Xenecore racquests made?

The conventional racket is made by inflating the carbon fiber frame under pressure by putting air into the end of the racket handler like a balloon.Donnay racquets are not made by air pressure, but by heating multiple microcapsules inside the carbon fiber frame and the microcapsules are inflated to fill the inside of the frame with pressure.

Xenecore is patented in 50 countries.


Xenecore provides Superior Shock & Vibration Absorption, results inNO MORE chronic Tennis Elbow, Shoulder or Wrist Injuries.No other brands are making such a claim, or offereing a satifaction warranty, for if they did, they would be taking racquets back as fast as they could sell them.

OVER 50%

of recreational & club members, who have been playing tennis for more than a year suffer from some kind of arm injuries in their playing career. The cause of the arm injuries can be due to improper tennis form, but the fundamental causes are mostly attributed to SHOCK & VIBRATION caused by hollow racquet frames made by other brands.


caused from the impact is transmitted through the hollow cavity to your hand resulting in unwanted injuries.  Countless professional players are quitting tennis due to wrist, elbow, and shoulder injuries!  Also, If the racquet frame is hollow, it is less stable, causing racquets to twist from the impact resulting in less ball control.

70% LESS

When the inside of the frame is filled with our multicore technology, the vibration is reduced up to 70% compared to other racquets.  This prevents elbow injuries, and the stability of the frame is increased for more power and control on your shots.

Back when tennis racquets were made from trees, a company called "Donnay" owned and operated by a Belgium furniture company, was by far the most popular tennis brand of racquets in the world.

It seems like every major champion and tennis great before the 90’s used a Donnay racquet, from Rod Laver to Margaret Court and, of course, Bjorn Borg, who became as synonymous with Donnay as his "ice man" image for his calm-court demeanor..In 1981, Donnay produced the most racquets in the world, but the company was slow to transfer to graphite frames and pretty much sat out the decade until it remerged with its own graphite model that Andre Agassi famously used to capture his first Grand Slam title -- Wimbledon in 1992.
