If you are looking for something different than you have found it. This is the uni-directional carbon fiber ring. It has the carbon fibers running in one directin vs. the woven fabric pattern that we offer. It is often used in cases where stiffness and weight really matter. Using this method it is possible to design strength in a particular direction without the weight penalty that comes with the woven pattern. The fibers have been also finished in our Endurance Matte finish that will also really tone down the ring. Available in all standard ring sizes 4.5 up to a 13.5! Approx width is 9mm.
