Note that folks who are seeing the cable fray after normal usage within the warranty period, you should reach out to Framework Support for a replacement cable. We’ve root caused this with our cable supplier and believe that there was a limited number of cables where molding of the sleeve wasn’t done at the optimal temperature. They’ve since adjusted the manufacturing process to resolve this.
It is still normal TPE-jacketed cable though, so over heavy use over time, there is risk of the jacket wearing at stress points. This is part of the reason we designed the USB-C cable to be detachable and replaceable. Much cheaper and less wasteful to replace a cable than a whole power adapter!
