Berd Bring Their String Spoke Technology to New Hubs
@R-M-R: Spinergy and Berd spokes are made from very different materials, the PBO polymer used by Spinergy is actually very rigid, even more so than steel (PBO Young's Modulus is 270 MPA, 304 Stainless Steel is 200 MPA). They make the spoke as a bundle of 30,000 PBO fibers wrapped in a composite jacket, so you can bend it easily, but it still has a high tensile strength and rigidity along its long axis. Considering how Spinergy claims their spokes are 3x stronger than steel spokes, it's possible that they are also stiffer than steel as well. Kinda cool how dissimilar they are from the Berd spokes in that regard, at least on paper.
