The Airush Progression Bar gives riders the opportunity to have industry standard safety and strength without the added features and adjustability of the Airush Core Bar. The Progression Bar includes the 45-52cm adjustable bar ends, which allows it to be used on any Airush 4 line kite from 4-14 meters. Together with 24m flying lines (with 10m and 14m extensions), the Progression Bar complies with IKO and BKSA teaching standards with quick and easy line changes, as well as single-line flag out safety. Airush Bars have safety as the first priority. Industry standard Brain Quick Release and color-coding on all parts makes the Airush system perfect and hassle free for all riders. Continuing from 2016, the Low Y on the center–lines allows for a quick, single line flag out for those situations where you need it the most.
