Swix Triac 4.0 Aero is the most winning pole in the World Championship and Olympics over the last few years. Skiers like Frida Karlsson, Therese Johaug, Hans Christer Holund, and Jessie Diggins all compete with this pole. This model follows the new measuring system for poles. Triac 4.0 Aero is the result of continuous research, testing, analysis, experiments and process improvements. Performance and nothing else has been in focus. The new shaft has a completely new cross-section for optimal stiffness and reduced air resistance. Stiffness has been improved by more than 15% in comparison with its predecessor Triac 3.0. Testing in the wind tunnel confirms up to 20% reduction of the drag coefficient in critical areas of the shaft compared to a shaft with a cylindrical cross-section. Swix Triac Aero is 100% compatible with the Swix TBS and TCS systems and provides top performance under all possible conditions. Triac 4.0 Aero is made of high-modulus carbon fibre which means the material is extremely light, resilient and strong. This is to provide maximum performance. In order for the product to have the longest possible service life, we do not recommend to use theses for roller skiing as they may then be exposed to stone chips, asphalt, road verges, etc. Specific roller ski poles are designed to withstand these kinds of impacts, while these are not. Avoid knocks or impacts during transport and under normal use. We strongly recommend the use of our pole bags for the best protection for your poles.
