DESCRIPTION This is a replacement part (#2 and #3 on diagrams) for the steering lines of the Core Sensor 2, 2s, and 3 control bars. The lines included in this set are intended for Sensor bars that have an overall length, from the bar to the kite, of 24 meters. TECTANIUM® POWERLINES Strong and durable. The front lines from the "Y" to the chicken loop use our exclusive, low stretch, Tectanium. And we protect it with a 5.2mm, UV-stabilized, Polyether where it passes through the bar. Techno speak for really durable, self-lubricating, no pinch, depower lines. The virtually frictionless, depower/safety lines are more aerodynamic, provide better feedback, and are more comfortable between the fingers. Just wait till you try it. You'll see. Pre-stretched top quality lines SPLICED ENDS For a better hold. We splice all our ends before sewing for a more permanent hold. It's a little more work, but this method guarantees higher strength and better aerodynamics.
