Je, je, es lo que tiene el carbono, que no avisa antes de romper...
Según el website RRD 2010:

"Program: Wave Twinzer PRO
Features: A wide and thick nose shape allows to use the whole rail line to increase the potential grip during turns. A very narrow tail helps the manouverability and control at hi-speed. A full concave into double concave middle shape and a flat tail increase planing potential to create an unbeatable mix of power and control. A new sensation for the world of pro waveriders.
Technology: Exclusive custom made full sandwich with triaxial carbon deck in clear vision white pigmented Epoxy/Herex 100 stringers on bottom."
