The ArcSaber 11 Pro is crafted using the new Neo CS CARBON NANOTUBE to provide added bite to the shuttlecock and the new SONIC METAL to increase the ability to deliver a high repulsion, rapid-fire return. The Yonex ArcSaber 11 Pro is designed to deliver pinpoint accuracy in the heat of lightening fast rallies. Neo CS CARBON NANOTUBE, refined by YONEX engineers, allows the racquet to achieve new levels of frame flexibility holding the shuttle on the string bed for even longer, for greater control at the point of impact, to allow you hit counter receive shots with the accuracy and speed you need to kill the point.
