Stringing information for Donnay Pro One OS Ext Racquet: None available

With its extended length (27.5 inches) and meaty swingweight (334 RDC), the Pro One OS Ext will provide intermediates with easy power and spin. Players with medium strokes will have no problem getting sufficient depth. The 105 square inch head and even balance provide a stable platform against pace, especially on block volleys. The extra length translates nicely into big serves. Our testers found this frame to play lighter than its swingweight, offering excellent maneuverability on reaction volleys and service returns. The open pattern provides a forgiving feel and plenty of bite. A great option for intermediates looking for controllable power in a comfortable package.

Dual Core

The Dual-Core racquets have a second layer of Xenecore tubing on the inside of the hoop that futher fortifies the frame and eliminates the loss of energy on ball contact.


XeneCore is a new fiber technology that uses high-pressure solids to form and reinforce the graphite fiber composite to incredible levels of strength that has allowed Donnay designers to reduce the thickness of the racquet beam width to a dramatic 15 millimeters, the thinnest in tennis. The thin beams greatly reduce air resistance (the same reason that sleek sports cars outperform bulky SUVs in wind-tunnel tests) providing unparalleled levels of maneuverability. The high-tensile strength of XeneCore also dampens vibration and provides unexpected power, while reducing the "shadow effect" from the beam blocking a portion of the string bed on off-center hits resulting in "frame shots." The net result of XeneCore technology is a previously unachievable level of all-around performance.
