This furler is set apart by the engineering of the cable in the system. While there’s a variety of systems on this market, this cable stands out as the height of technology. Think of a figure skater, when they start spinning fast, they pull their arms in to keep everything tight, with the GX furler by Selden, the same thing happens. It’s very stiff, and resists twist due to a special heat treatment during the construction process and the way the cable is constructed. Starting with the plastic rod core, the furling cable is non-compressible, and it’s dynema surrounding allows for exceptional strength in tension which allows for speedy rotation on a tight axis.
