Berd spokes are made from an advanced polymer called ultra high molecular weight polyethylene (UHMWPE). UHMWPE has 12 times the strength-to-weight ratio of steel and floats on water. The key aspect of our technology is the connection between the polymer and the steel threads, which relies on the "Chinese Finger Trap" effect to create an 'unbreakable' bond. This technology was developed in partnership with the National Science Foundation through a Small Business Innovation Research Grant and is protected by US Patents 10,150,332 B2 and 10,661,598 B2.
