Taking O3 technology to a whole new level with rectangular O-ports, the Speedport Red is built for speed and power.  Rectangular ports allows the Speedport Red to swing 24% faster through the air and when combined with the DPR string pattern this frame tops out as one of Ektelon’s most powerful racquets. The Speedport Red can be customized with Ektelon Power Plugs  around the entire frame. It’s like having 7  different racquets in one!
