Over the course of our development of the Dynocore™ project the boards have been put through many stressfull situations. Initial variations showed some weakness that constant refinement and adaptations of materials overcame. Good reasons for application of fibres like Innegra™ and Carbon. Innegra™ has 3 times the elongation (ability to stretch) than regular 4 oz fibreglass cloth. The variable desity EPS foam has a built in memory that in unison with the fibre/resin combination magically minimises the deck denting your feet put in the board overnight!
