CFT // RCS Stringer
CFT (Composite Fibre Tube) or RCS (Responsive Composite Stringer) stringer's are a hollow composite fibre rod that are added to the core to provide more structural strength. Bodyboard core's are drilled out, usually through the middle & centre of the board. The stringer is then inserted before the core is laminated. Bigger boards or boards that require more strength can have 2 or 3 stringer's to add stiffness. These stringer's are strong yet lightweight & are usually added to premium polypro core models.
