Since its successful introduction two years ago, SRAM's popular single-ring 1X drivetrains featuring X-SYNC chainrings continue to gain popularity. In an effort to provide consumers more choice SRAM has licensed this precision-based technology to two industry partners.
Last month, SRAM formally signed two license agreements for the technology, one with Canadian-based Chromag, the other with the Accell Group. Both of these top-tier industry suppliers will be manufacturing their own versions of SRAM's X-SYNC rings to be distributed through their own networks. Both suppliers will continue to use and support all SRAM 1X Drivetrain components in addition to this license.
This narrow-wide design (also referred to as thick-thin) is an original SRAM technology, designed and engineered to be paired with matching SRAM components to ensure proper function. Imitation rings not manufactured to proper SRAM specifications may result in rapid wear and poor mud clearance, both of which may result in dropped chains.
SRAM has filed numerous patent applications on narrow-wide / thick-thin tooth geometry. Our German engineering teams invented narrow-wide / thick-thin chain retention for bicycles and we continue to improve on it. We strongly believe consumers deserve both choice and design integrity in the products they purchase. SRAM reserves the right to enforce its intellectual property in all matters relating to X-SYNC.
