Replacement Bar for Navigator Pro. Adjust the bar size to fine-tune the turning speed of your kite. You have the option of 45-50cm or 50-55cm bar lengths to match our full range of kites and give the desired amount of leverage. The cassettes ... on either end of the bar enable the bar length to be extended or retracted by 5cm - simply pull them out, rotate 180 degrees and snap back into place. Soft bar ends ensure nothing hard comes in touch with you or your board and contain rear line adjustment. The integrated retractable line winder bungees prevent tangled lines when packed up. (Bungee retracts when not in use.) Not compatible with Navigator Pre-2024.
