They weren't and as far as I know aren't just yet. I've worked with @Brucecris for a long time developing my wheels and we just sorta became good friends. We both thought Rotora was too expensive for what you get and wished racing brake did a rear caliper. He did some research and came up with an option and we both ordered up some sets. There are some teething issues for sure so I'm not sure if SuperForged is going to make them an official offering yet but they work perfect.
