To activate this bar feature, you need the Micro Hook upgrade kit. The Micro Hook system allows a way of riding, with the North bar permanently hooked in. This setup transfers a larger percentage of the load to the harness and reduces arm fatigue. To connect or disconnect, pull the bar towards you and twist it. The Fix Loop is placed at an angle that makes accidental hooking impossible. The construction with Dyneema line inside the loop is more resistant and durable. In case of emergency simply pull the quick release mechanism at the iron heart and the kite will depower.
