Thats the Redster G9 FIS Revo S. It features Atomics World Cup-winning Revoshock – a series of spring steel plates embedded in an integrated elastomer compound that eat up bumps on the racecourse to create a stable ride that accelerates hard out of the turns. Full-length sidewalls and Atomics Ultra Titanium Powered laminate create powerful edge grip and torsional rigidity. The Ultra Power Woodcore works together with the Active Race Interface binding platform to transmit all your input directly into a ski that responds at the speed of thought
