Head Graphene Speed Pro (Djokovic) Racquets Technologies
Graphene is an ultra-light and ultra-strong substance which is 200 times stronger than steel. Head places Graphene in the shaft so that weight can be redistributed to more functionally relevant areas of the handle and tip. This unique construction provides players with increased swingweight for more power with less effort.
