This ring is constructed entirely of Carbon Fiber. It is woven on a machine I designed and built, and the exterior weave is a small one-over, one-under type of weave, known as a "plain weave". The woven features of this ring are appropriately sized to the ring, not large weaving like is found on commercially available carbon fiber fabrics, etc.
This is a very strong, lightweight ring. Made to order in the size and width of your choosing.
