Dynamic Recoil Calibration

Dynamic Recoil Calibration™ uses structural flex simulation technology to create specific shaft weave patterns that optimise the performance characteristics of each ISS® stringer flex. By incorporating DRC into our design process, we are able to reduce shaft weights while greatly improving the strength and recoil properties of ISS stringers. 


Polymer Sleeve Insulation

The Interchangeable Stringer System® incorporates a lightweight, high strength polymer tube, ultrasonically welded to form a flexible sleeve that insulates the stringer cavity from the core. 


Load & Lock™

Imagine changing the flex of your board with the turn of a key. With ISS® Load & Lock™ technology, fine tuned board flex is now a reality. To load, select your desired ISS stringer flex and insert into the empty chamber. To lock the stringer in place, insert the ISS key into the keyhole located at the end of the ISS Stringer and turn clockwise until full lock is achieved. To reload, just reverse the process. It's that easy.
