Carbon Reflex Sandwich
THE FLAGSHIP CONSTRUCTION
The iSonic Carbon Reflex is our flagship range. The light weight allows you to get going easier, plane through wind holes and get the best top speed. Carbon Reflex is our stiffest construction, giving you the best control when hitting chop and waves. Decks are built with the lightest grade of biaxial and uni-directional carbon fibre orientated between 45, 30 and 0 degrees for optimized flex and reflex characteristics. The bottom of the boards use an even lighter grade of uni-directional carbon fibre from nose to tail, with an extra 45 degree biaxial carbon layer in the tail area for added torsional stiffness.
